時間領域二次元面外波動場境界要素法へのパネルクラスタリング法の適用

抄録

The application of transformation methods such as the Fourier transformation is difficult, when the boundary condition is implicitly given and changes with time such as in time domain problems. We consider that solving this kind of problem by applying time subtraction solution method. When time subtraction solution method is applied, domain integration of theapparent body force requires a huge amount of computation. In this paper, the panel clustering method is applied for this domain integration, and the reduction of a huge. amount of computation is being attempted. This method is applied to the anti-plane wave field problem, and it is confirmed that the amount of computation was drastically reduced.
