    AbstractThe visualization of computer simulations is currently undergoing a transition from post-hoc to in-situ visualization in which visualization processes are applied, while the simulation is running. The selection of an appropriate method or tool is essential to efficiently perform in-situ visualization in parallelized large-scale computer simulations that run on supercomputers. Although some generic in-situ visualization libraries are available, they are overengineered for certain geophysical simulations. In this study, we focus on spherical simulations using the Yin-Yang grid. Computer simulations that use the Yin-Yang grid are gaining popularity in geophysics. We propose an in-situ visualization method dedicated to the Yin-Yang grid simulations and demonstrate its effectiveness through sample simulations.

    We propose a new visualization method for massive supercomputer simulations. The key idea is to scatter multiple omnidirectional cameras to record the simulation via in situ visualization. After the simulations are complete, researchers can interactively explore the data collection of the recorded videos by navigating along a path in four-dimensional spacetime. We demonstrate the feasibility of this method by applying it to three different fluid and magnetohydrodynamics simulations using up to 1,000 omnidirectional cameras.

    Recent advances in head mounted display (HMD) systems, specifically those demonstrated by the Oculus Rift, provide a new platform for three-dimensional scientific visualization. Taking advantage of this opportunity, we have constructed a cost-effective video see-through visualization system by combining a stereoscopic camera system and an Oculus Rift device. The see-through HMD system enables a researcher to analyze numerical data in a virtual reality space, with keeping visual communication with nearby collaborators in real space. We have ported our visualization software for CAVE systems, VFIVE, to the HMD system. The ported software enables its user to analyze three-dimensional scalar/vector fields in a virtual reality space while simultaneously being able to view the natural surroundings.

    A high-speed rendering method for three-dimensional animated volume rendering in a CAVE visualization environment is developed. The proposed method accelerates the standard three-dimensional texture-slicing approach to volume rendering by making use of asynchronous data transfer with the pixel buffer object of graphics processors. The method enables stereoscopic animation of volume rendering at five frames per second for scalar data of 5123 grid points in a four-screen CAVE system.

    To analyze large scale 3-dimensional data, the modern virtual reality (VR) technology will play important roles in future simulation studies. Various VR visualization programs have been developed to date, including our original VR visualization software VFIVE. However, almost all of the previous VR software are based on CAVElib, which is a de facto standard commercial library for VR environments. To replace the basic API from CAVElib, we are developing a new visualization software based on VR Juggler which is an open source free software library. Our program design and implemented visualization methods are reported in this paper.

    We performed MHD geodynamo simulations with low Ekman number Ek=O(10E-7), which is the lowest value yet achieved. We found that the convection, magnetic fields and current fields structure are different compared with higher Ekman number cases. The convection is made of thin sheet plumes. By dynamo action under this convection motion, magnetic flux tubes are formed. Also helical current coils and some current tori are formed. Purely zonal flow is formed around the end of the plume.

    For interactive data analysis of large scale simulations, we are developping a virtual reality (VR) visualization software called VFIVE. VFIVE uses OpenGL and CAVE library to generate and interact with virtual objects in a CAVE VR system "BRAVE" installed in the Earth Simulator Center. The development of VFIVE and its application to geoscientific data obtained by computer simulation on the Earth Simulator is described.

    One of the most practical objectives to use the virtual reality system in science is to make it easy to intuitively percept complex physical phenomena. We developed a virtual reality system, called CompleXcope, which can represent "real" 3D visual environment. Since attractive physical phenomena are often so complex and tangled, the virtual reality system with 3D-sound functions is really useful for the quick comprehension of phenomena. We have recently added a sound function to the CompleXcope. In this paper we present examples produced by this aural-visual virtual reality system "CompleXcope".

    地球内部の大部分を占めるマントル層の下には外核と呼ばれる液体鉄の領域がある.液体鉄は電気伝導性の流体なので,外核の流れと磁場は磁気流体力学(MHD)方程式に従う.この液体鉄を媒質としたMHDダイナモ過程により,地球磁場(地磁気)が作られている.長い歴史をもつ地磁気の研究は,計算機シミュレーションの手法が導入された1990年代半ば,飛躍的に発展し,その後もスーパーコンピュータの進歩に伴って着実に進歩してきた.MHDシステムとしての地球外核の特徴の一つは,地球の回転(自転)が流れに及ぼす影響の強さである.その強さはEkman数とよばれる無次元量で示される.本章では,地球ダイナモの特徴を概観し,シミュレーションで実現されたEkman数の漸進という視点からまとめた地球ダイナモシミュレーション研究の成果を紹介する.

    スーパーコンピュータで実行される計算機シミュレーションの複雑化と大規模化は今後ますます進むであろう。従ってデータ可視化にも新しい技術の積極的な導入が必要とされる.3次元シミュレーションのデータは3次元のまま可視化し,解析することが望ましい.シミュレーション研究者にとって理想的な可視化環境とは,自分の計算機シミュレーションの世界に自分の体ごと没入し,そのデータを自分の手で直接操作することを可能にするような環境であろう.最新の没入型バーチャルリアリティ装置を使えば,そのような理想的なデータ可視化環境を程度実現することが可能である.本講演では,神戸大学統合研究拠点に導入された没入型バーチャルリアリティ装置『π-CAVE』と,そこに実装した様々な可視化ソフトウェアについて紹介する.

  • Geodynamo Simulation and its Visualization by Virtual Reality Technology

    地球は巨大な発電機である。地球内部のコアと呼ばれる領域にある液体金属が対流運動し、その流れが電磁誘導を通じて自発的に10億アンペアの西向きリング状電流(即ち双極子磁場)を作り出している。コンパスが北を指すのはこのためである。さらにこのリング状電流は数十万年に一度、突然向きを反転させることが知られている。双極子磁場の自発的な生成と逆転というこのような地磁気の興味深い性質は、磁気流体力学(MHD,Magnetohydrodynamics)方程式の時間発展を数値的に解く、地球ダイナモシミュレーションと呼ばれる手法により計算機の中で再現されている。地球ダイナモシミュレーションの概要と、これまでに得られた成果、並列スーパーコンピュータを駆使した大規模計算を実現するためのシミュレーション技術的な工夫について述べ、さらに、その計算結果を3次元的に解析するために導入したバーチャルリアリティ技術、及びそれを応用した3次元的・対話的・没入的な可視化手法の開発についても紹介する。

    The operation of the Earth Simulator started in March, 2002, and 7 years have passed. For these years, the Earth Simulator has been used by not only researchers of JAMSTEC but also many researchers of the domestic and international institutions, and many remarkable results have been made. The Earth Simulator Center was established at the same time as the birth of the Earth Simulator. The researchers of the Earth Simulator Center have also developed new simulation technologies.The simulation is the only one method by which we can predict the future scientifically. Therefore, it has the important role in the science as well as the technology which can contribute to the life of the people, and has the important meaning in modeling the future of the human beings.

    The physics of quiet auroral arcs formation has been studied with Macro-Micro Interlocked (MMI) simulations. In the macro part of our simulation code, the macroscopic instability between the magnetosphere and ionosphere is described by the magneto-hydro-dynamics (MHD) model. On the other hand, in the micro part, the microscopic instability is calculated by the particle-in-cell (PIC) model. In the MHD simulation, it is shown that longitudinally striated structures of the field-aligned current are formed by an ionospheric feedback instability[1]. Further, the emission of aurora arc is obtained from the energy spectrum of accelerated electrons with the PIC simulation. [1] T. Sato, J. Geophys. Res., 83, 1042, 1978.

  • Numerical Simulation on Laboratory Experiment of Magnetorotational Instability : Circulation in a Taylor-Couette Flow
    Kageyama Akira, Ji Hantao, Goodman Jeremy
    Aiming the first laboratory demonstration of magnetorotational instability (MRI), a liquid metal MHD experiment is undertaken at Princeton Plasma Physics Laboratory (PPPL). In order to produce a flow stable to hydronamic modes but unstable to MRI, a prototype water experiment in the same geometry has been performed. The initially proposed experimental setup consists of two concentric sbort cylinders rotating at constant angular velocities. However, preliminary data indicate that the toroidal flow profile in this cylindrical, or rather a disk-like, vessel is strongly affected by the vessel's horizontal boundaries (the lid and the bottom). Since the profile control of the toroidal flow is essential for the MRI experiment, we performed 2-D numerical simulations of this Navier-Stokes system to understand the flow structure and the boundary effect in detail. The simulation model, results, and comparison with experimental data will be presented in this talk. A poloidal circulation flow is driven at the boundaries by an Ekman-like effect. We found, in our numerical simulations, that a jet structure is formed as a part of the poloidal circulation. This poloidal circulation significantly modifies the toroidal flow from its preferred profile for the MRI experiment. A remedy to remove or minimize the effects of the poloidal circulation will be also presented.

    本研究では、大規模数値シミュレーションによって計算される数値データに対して、時間・空間・変数に関する3つの指標を設定することによって可視化すべき 時空間領域を効率よく推定し、In-situ可視化における画像化時間の短縮だけでなく、数値データからの科学的知見を獲得するまでの時間を短縮することができる スマートIn-situ可視化を実現することである。 本年度は、昨年度までに開発していた適応的時間サンプリング手法と最適視点推定手法の実装上の最適化を進めると同時に、それらを構成する処理要素の抽象化を行い、スマートIn-situ可視化を実現するためのフレームワーク化に成功した。本フレームワークについては、スーパーコンピュータ富岳環境での動作を確認しており、今後本格的な評価実験を実施する予定である。 また、本年度は、最適視点推定法について、新たな手法の開発に着手した。昨年度開発した手法では、空間内に配置した多数のカメラ画像から、それらの画像の差に注目することで重点領域の推定を行なっていた。結果として、撮影画像の枚数を効果的に削減することに成功したものの、注目する物理量の時間変化を動画像として再生する際に困難が生じていた。今年度は、この問題に対して、一定の時間間隔で画像エントロピーを計算することで最適視点を推定し、その視点を接続する移動経路を計算する最適視点経路推定法を開発した。本手法を歯茎摩擦音発生シミュレーションに適用し、その有効性を検証した。 さらに、本年度は、新たな計算指標となる因果探索手法の開発に着手した。現在、因果探索手法の一つである移動エントロピー法を実装し、予備的実験として気象アンサンブルシミュレーション結果に適用し、その効果を部分的に確認しているが、改善すべきいくつかのポイントも明確化された。今後、提案するIn-situ可視化フレームワークへ組み込み、効率的に改善手法の開発を進める予定である。

    In order to construct a collaborative visualization environment, which based on the virtual reality technology, between different VR devices, a C++ library that is able to built a HMD executable binary file without modification to the source code written using CAVELib that is a C ++ library to develop application software for CAVE devices was developed. I succeeded in commonizing the source code between CAVE and the currently major HMDs through this development, and were able to establish an infrastructure for the collaborative visualization environment.

    In this study, we analyzed the distribution of neuropeptides in the Ciona brain using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) imaging mass spectrometry (MS) based on our previous peptidomics data. Major Ciona neuropeptides were detected on a single brain section, and the images of their distributions were acquired with a spatial resolution of 20 micro meters. We further developed a method for high-resolution imaging MS by a combination of fluorescent microscope and imaging MS in the brain sections of transgenic Ciona that expresses fluorescent protein in neurons. The high-resolution imaging MS for the first time showed the distribution of four peptides in a single brain section at single-cell resolution. Both the high-resolution imaging MS and immunohistochemistry using specific antiserum against the neuropeptide Ci-TK-I yielded similar results, suggesting that the high-resolution imaging MS has a potential to serve as a new platform for histology.

    We explored magnetoconvection and rotating convection by means of laboratory experiments and numerical simulations, to elucidate the mechanism that induces geomagnetic polarity reversals. We established a regime diagram of convection in a liquid metal under the influence of imposed horizontal magnetic field. The searched space is summarized by the relation between buoyancy and magnetic force, in which a regime exists that reversals of flow direction repeat intermittently. We found that the key mechanism for flow reversals is an occurrence of large-scale circulation in a horizontal plane. We also performed numerical simulations of dynamos in a rotating spherical shell, and clarified the relation between polarity reversals and transitions of convection flow.

    Laboratory experiments on the turbulent thermal convection of a liquid metal under ambient magnetic fields with various intensities were carried out. Consulting with the observed variations of the geomagnetic field and the results of geodynamo simulations, we tried to infer the turbulent state and the energy dissipation in the Earth's core. In the experiments, we found spontaneous reversals of the flow patterns of thermal convections within a certain range of the intensity of the magnetic fields and the Rayleigh numbers, which might be important to understand the origin of the geomagnetic field reversals.

    The interface between plasma core transport code TASK/TOPICS and edge divertor code SONIC has been developed, which enables the self-consistent integrated transport simulation for whole plasma. Using this code, the heat flux into diverter plate has been evaluated in the self-consistent manner. The results were reported in 23rd IAEA Fusion Energy Conference 2010. In addition, the multi-scale, multi-physics simulation study on fusion plasma has been performed. It is found that non-local effect due to the nonlinear interaction plays a role on non-local transport and transient phenomena in fusion plasmas. Near future, these findings will be cooperated into the transport model for ITER plasma analysis.

    The macro-micro interlocked (MMI) simulation is a new framework of numerical simulation, which is capable to deal with the interaction of multi-scale and multi-physics phenomena. In this study, we have developed the basic algorithm of the MMI simulation, and applied it to solar and space plasmas including solar flare and coronal mass ejection, as well as to the formation of cloud, in order to advance the capability of numerical simulations. In addition, we have developed the study for space weather forecasting with the MMI simulation.

    The Earth's magnetic field has two intriguing features ; one is its dipole nature ; and the other is its reversal of the north-south polarity. The purpose of this study is to simulate these features of the geomagnetic field and to understand the physical mechanism behind it by means of large scale computer simulation. The simulation model is as follows : We consider a spherical shell region between two concentric spheres. The temperatures of the spherical boundaries are kept constant and uniform ; the inner sphere is hot and outer sphere is cold. An electrically conducting fluid is confined in this spherical shell region, corresponding to the liquid iron in the Earth's outer core. When the temperature difference is sufficiently large, convection motion of the electrically conducting fluid sets about. The fundamental equations are the magnetohydrodynamic (MHD) equations with time development equations of temperature field. As a result of our computer simulation, spontaneous generation of dipole magnetic field and its intermittent reversals are successfully reproduced. detail analysis of the simulation data indicates that the dynamo-generated magnetic field has two stable states ; one is high energy state and the other is low energy state. One of interesting findings in this simulation is hat the dipole reversals take place only in the high energy state. Another interesting finding is that quadrupole moment grows, exceeding the dipole moment before the reversal. The computational grid system used in our simulation, by which we could successfully reproduced the dipole field generation and reversals, were spherical latitude-longitude grid. When we applied this code to the Earth Simulator, we found that the latitude-longitude grid is not suitable to this vector-parallel architecture. We, therefore, devised a new kind of spherical grid system based on the overset (or Chimera) grid methodology, and named it Yin-Yang grid. The Yin-Yang grid is successfully applied to the spherical shell MHD dynamo simulation.

    CAVE方式(あるいは没入ディスプレイ方式)のVR(Virtual Reality)装置を利用して、科学研究データを立体的に表示・解析するための汎用プログラムVFIVEを開発した。VFIVEは3次元の場のデータを、そのデータの中に「入り込んで」解析することを目的としており、特に磁気流体力学(MHD)シミュレーションのデータ解析や、流体力学のシミュレーションデータ解析に威力を発揮する。VFIVEプログラムのユーザは、指定されたフォーマットでデータを用意すれば、コマンド一つを打ち込むだけで、すぐにそのデータを立体的・対話的に解析することが出来る。VFIVEはC++言語で書かれており、その内部で利用する基礎ライブラリはCAVEライブラリとOpenGLだけである。そのため核融合研のVR装置CompleXcopeだけでなく、その他のCAVE方式VRシステムに容易に移植可能である。現在のVFIVEが持つ主な機能は以下の通りである。(1)3次元ベクトル場の力線(磁力線や流線など)の対話的な追跡と表示。(2)3次元ベクトル場の立体矢印の表示。(3)手の位置からのテストパーティクルの放出。(4)3次元スカラー場の等値面の表示。(5)スカラー場の断面分布の表示。 本年度は、このVFIVEの第1版を完成させた。また、日本語マニュアルの整備も行った。この日本語マニュアルは研究代表者のWebサイトで公開している。これまでに、このVFIVEプログラムは、(a)乱流シミュレーションの解析、(b)太陽コロナ磁場の解析、(c)MHDダイナモシミュレーションデータの解析、等に実際に応用した。

    回転球殻中の磁気流体(MHD流体)の熱対流運動によるMHDダイナモを計算機シミュレーションにより研究した。MHDダイナモ過程により生成された双極子磁場が突然逆転する現象の再現とその機構の解明が本研究課題の目標であった。シミュレーションモデルは以下の通りである。半径の異なる二つの球面に挟まれた球殻状の容器を考え、その中にMHD流体が閉じ込められているものとする。内側の球面は高温、外側の球面は低温にそれぞれ一定の温度に保たれており、球の中心方向に向かう重力が存在する。球殻全体は一定の角速度で回転している。この様な回転球殻容器内部のMHD流体の熱対流運動の時間発展を解くと、あるパラメータのもとでは、MHDダイナモ作用により、双極子磁場が自発的に生成されることがこれまでの我々の研究で明らかになっていた。本年度はこのシミュレーションモデルの元でさらに広範なパラメータランを行い、生成された双極子磁場が突然逆転するパラメータを発見した。逆転時の磁場エネルギーの変化を調べたところ、双極子磁場が逆転する時に磁場のエネルギーレベルが突然変化することが判明した。さらに時間発展を進めると、磁場のエネルギーには高い状態と低い状態の二つがあり、その二つのレベルを予想出来ないタイミングで突然遷移することが分かった。興味深いことに双極子の逆転が起きていない時のエネルギーレベルの遷移では八重極成分の逆転が起きていることが観測された。磁場のエネルギーレベルが二つあるという事実と、その間を遷移する瞬間に双極子成分か、八重極成分が逆転するという現象を見つけたのが今年度、本研究により明らかにされた最も重要な点である。

    Based on agreement on academic exchange between National Institute for Fusion Science (NIFS) and the Australian National University (ANU), which was concluded on May, 1995, this project has aimed at understanding physics mechanism of various plasma phenomena occurring in toroidal geometry like the helical system plasma. 1. Concerning plasma theory, magnetic island formation and self-healing in three dimensional finite pressure equilibria, linear stability and nonlinear time development of pressure driven instabilities, optimizationof magnetic field configuration for helical axis stellarator, plasma self-organization, and development of advanced visualization technology by using virtual reality system are studied successfully as collaborative researches. 2. As for plasma heat ingexperiment, a device for electron cyclotron resonance heating was developed as a collaborative research, and was applied for the H-1 helical device in ANU.In addition, possibility of plasma heating by using ion cyclotron resonance heating was analyzed and proved to be valid in the complex geometry of helical axis stellarator. 3. Comparative study of plasma confinement between CHS in NIFS and H-1 in ANU has been executed, and common properties concerning fluctuation-driven particle flux was revealed. The new knowledge suggests existence of improved confinement mechanism not only for stellarator, but also for tokamak plasnas. 4. Innovative methods for diagnosis of plasma density have been developed out of collaborative research, and were proved to be of practical level by applying the device in LHD plasma measurements.

    We have investigated the details of complex phenomena in rich variety of non-equilibrium open systems in collaboration with scientists In Japan, U.S.A., Europe and Asia. The summary of our collaboration research is described in the following. (1) We found from the MHD simulation that a strong magnetic field with a global and ordered structure is spontaneously generated by the MHD dynamo process in a rotating spherica1 shell, and its polarity is suddenly reversed after a long duration. (2) We have studied the merging process of two col1iding spheromaks, and found that a field-reversed configuration with a high pressure is formed through this process. (3) We have studied the physical process of collisionless driven reconnection by means of particle simulation. It should be emphasized that magnetic reconnection evolves in two steps due to two kinetic effects and the ions anomalously heated by the action of an electrostatic field. (4) Particle simulation has revealed that a super ion-acoustic double layr with a large potential gap is generated after the generation and disappearance of a norma1 ion-acoustic double layr if there exists an entropy expulsion process in an open system. (5) We have developed a particle simulation code for dust grains with dynamically charging processes, and clarified the condition under which the coagulation of dust grains takes place. (6) We have investigated the structure formation process at a molecular level by carrying out a molecular dynamics simulation of polymer chains . It is emphasized that the structure formation of polymer chains proceeds in a few steps. (7) We have developed three-dimensiona1 interactive data visualizing system "CompleXcope", which is a new application of the virtual reality system, as a powerful tool to comprehend complex phenomena.

    磁気流体ダイナモの物理機構の解明を目指し、計算機シミュレーションによる研究を行った。考察した物理系は次の通りである。半径の異なる二つの球面にはさまれた球殻状の容器を考え、その内部に磁気流体が閉じ込められているものとする。内側の球面は高温、外側の球面は低温にそれぞれ一定の温度に保たれているものとする。球の中心方向に重力が働き、球殻全体は一定の角速度で回転している。このような回転球殻中での磁気流体の熱対流運動を磁気流体方程式を差分化する方法で解いた。今年度の研究を通じて得られた結果は次の通りである。 1.対流運動は円柱状の対流胞(対流柱)の集まりとして組織化される。 2.対流柱には高気圧柱と低気圧柱の二つの種類がある。 3.電気抵抗が十分小さいときには、磁気流体ダイナモにより強い磁場が生成される。 4.磁場のエネルギーは対流の運動エネルギーの十倍以上にも達し得る。 5.あるパラメータ領域のもとで生成される磁場成分を分解すると、双極子磁場が最も強いモードになる。 6.その双極子磁場成分の生成機構は対流柱内での流体運動による磁力線の変形と引き延ばしで説明できる。 7.また、この双極子磁場生成機構は古典的なα機構の一つとしてで理解できる。 8.α機構で生成された磁場は球殻の外側球面近くでは、低気圧柱の内部に集中する。 9.この現象は低気圧柱内部の流れ成分により引き起こされることが判明した。 以上を簡単にまとめると、磁気流体ダイナモによる双極子磁場生成は円柱状の対流胞構造の自然な帰結であることが、この研究から明らかになった。

    We have investigated the detail of "Self-organization" phenomena in various spatial scale in collaboration with the people in U.S., Europe and Australia.The followings are some of the successful results we got in this research project.1) We have developed a new simulation code in order to reveal the dynamo mechanism in MHD plasma.We found that the convection motion of the rotating plasma makes a cell structure and forms a dipole magnetic field through the transformation of the kinetic energy to the magnetic energy.It should be emphasized that the magnetic reconnection plays an important role in the formation of the dipole magnetic field structure.2) We have studied the structure of the finite beta plasma in the helical system and found the following interesting and important self-organization process.Even if the helical plasma is initially unstable and the structure is destroyed due to the pressure driven instability, the ordered structure is formed again through the nonlinear interaction.It should be noticed that when the structure is formed, the entropy, i.e., thermal energy is generally produced.In this case, the thermal energy is the cause of the structure instability, and simultaneously it resulted in the ordered structure.3) We have developed a quite new particle simulation code for an open boundary system.We found the "Super" ion-Acoustic double layr whose amplitude is more than 20 times larger than the regular one.In this study, it can be pointed out that the entropy production rate becomes highest when the structure is made up, and the entropy expulsion mechanism plays an important role in the maintenance of the ordered structure.4) We alomost made up a general scenario of the self-organization process for MHD plasmas.One of the conclusion of this scenario is that the structure formation occurs intermittently and shows the recurrence depending on the way of energy input to the system. Besides above results, we have studied various self-organization processes such as the structure formation in a dusty plasma, or the crystallization of polymer in the liquid.Now, we continue this investigation aiming the construction of the general theory of "Self-organization".
