内容記述 | 分散メモリ並列計算機上で2次元非圧縮ナビエ・ストークス方程式を解いた。修正SOR法によるポアソンソルバーを16台のトランスピュータ(T805)列に組み込み、渦度と流れ関数で定式化した非圧縮ナビエ・ストークス方程式の解法に適用した。渦度輸送方程式の解法には、有理ルンゲ・クッタ時間積分法を用いた線の方法を採用した。並列化の方針として、構造格子上で偏微分方程式を解くのに領域分割法を用いた。129×129の格子上でポアソンソルバーを並列処理した場合、16台の要素プロセッサで15.7倍の計算速度、つまり効率0.98の結果を得た。非圧縮ナビエ・ストークス方程式の場合は、16台のトランスピュータに関する並列処理で殆んど比例的な15.96倍の計算速度、つまり効率0.998の結果を得た。 | |||||

内容記述 | The two-dimensional incompressible Navier-Stokes equations are solved on a distributed memory parallel computer. The Poisson solver based on a modified Successive Over-Relaxation (SOR) method is implemented on an array of 16 transputers (T805), and it is applied to solve the incompressible Navier-Stokes equations in terms of the vorticity-stream function formulation. The method of lines approach using a rational Runge-Kuta time integration scheme is adopted to solve the vorticity transport equation. As a parallelizing strategy, the domain decomposition technique is used to solve the partial differential equation on a structured grid. The result of the parallelized Poisson solver for 129 x 129 grid points gives high speedup of 15.7 and efficiency of 0.98 of computations on 16 Processor Element (PE)s. In the computation of the incompressible Navier-Stokes equations, an almost linear speedup of approximately 15.96 is gained and corresponding efficiency 0.998 is obtained through the present implementation of the parallel algorithm for 16 transputers. | |||||
