摘要: 本文提出了在六角形网格剖分的情况下,用傅氏变换数值求解波动方程初值问题的算法,并就二维线源柱面波场的模拟作了初步的试算,结果表明,六角形采样方式有较传统的矩形采样方式更好的模拟效果。

Abstract: The wave equation initial value problems are solved numerically on the grid of hexagonal sample by fourier method. A numerical test by this approach shows the availability and the efficiency over the rectangular sample.

Key words: hexagonal sample, wave equation, fourier transform, rectangular sample
