散射问题我没怎么做过。我在想,你是不是用直接边界元计算的时候,最后显示不正确,把整个声场显示出来了,而不仅仅是散射场。在VL里面有这个设置。如下图
Scattered/Total Field When you compute the sound scattering field using a plane wave, the pressures computed on the Field Point Mesh (FPM) are the total pressure (incident acoustic field+ scattered acoustic field). Hence, this feature allows you to compute the scattered acoustic field only (i.e. without the incident field from the acoustic sources) by selecting the Compute Scattered Field Only option. |
