    Abstract: 這是一個為期一年的基礎研究計畫。我們希望能研發一個高階隱式的多流塊電漿動力數值模擬碼,以便研究行星際激震波與地球艏震波附近所常觀測到的高頻微觀之大震幅電磁擾動現象。我們預期這個新模擬碼的雜訊將遠低於一般低階粒子數值模擬碼的雜訊。因此可以用來進行跨電子與離子尺度之物理過程的模擬研究。本計畫書中簡述如何進行高階差分與分散作業,以及未來將如何評估此模擬碼的優缺點。本計畫也將嘗試利用【加速圖形顯示界面卡】(GPU)進行GPU平行運算的程式研發。 This is a one-year basic research. To study the formation of high-frequency small-scale large-amplitude electromagnetic disturbances observed in the vicinity of the interplanetary shocks and the Earth's bow shock, we propose to develop a higher order implicit plasma kinetic simulation code, in which both ions and electrons are treated as fluid elements and each element has its own density, position, and velocity. We expect that the S/N ratio of this simulation code will be much higher than the traditional particle code. As a result, this code will be good for study cross-scale nonlinear plasma phenomena. The higher order deposition and interpolation scheme will be introduced in this study. To speed up the higher order plasma simulation, we will explore the latest parallel computational technique, GPU, and develop a GPU-based simulation code in this study. 研究期間:9908 ~ 10007
