1.三角形缺陷从几何中挖掉之后，物理场中无需进行设置。2.三角形区域是挖掉的，不需要设置材料。

那在请问两个问题：1三角形的缺陷是从主体材料中挖掉之后物理场设置该区域还是elte吗？2三角形的缺陷材料是不是设置成了空气还是其他？

动画中并没有对波形进行放大处理，三角形的缺陷是从主体材料中挖掉了一部分，无需再设置成裂隙。

Hello, I want to consider the influence of prestress under the elastic wave, time-domain explicit interface. Is it possible? Or I can only use solid mechanics interface under this working condition?

赶紧上个案例呀，尤其是高频压电无损检测，拜托

您好目前还没与相关案例，您是在哪里看到有相关网页的
