请教高手，我的换能器模拟一直没有算出来，下面是命令流请指点一下，哪里出了问题，谢谢！紧急中！
一纵向换能器，换能器由前辐射头（硬铝）、压电陶瓷（PZT-4）、后质量块（黄铜）、预应力螺栓（45＃钢）组成，结构通过去耦垫环（真空橡皮）与水密外壳（不锈钢）隔离，前辐射头用透声聚氨酯橡胶灌注密封。压电陶瓷I 与压电陶瓷II 分别代表极化方向相反的陶瓷。
请问压电陶瓷极化方向相反是不是设置压电应力矩阵分别为【e】和—【e】，介电常数矩阵和弹性常数矩阵不用变就可以了？

下面是我操作的命令流

我的计算结果，很奇怪求解域一片红色，看不到应该有的压力波，而且连旁边的颜色对比标尺都没有。

我划分网格中，固体结构边缘已经包含了含有结构自由度的FLUID29了啊，最外边也定义了吸收边界线单元FLUID129。请高手和版主指点一下！！谢谢了。

这个是莫喜平教授的一个例子吧？我手头上现在没有ansys软件，没办法帮你调试。不过你问的问题有关于设定极化方向的问题，我可以告诉你不用刻意改变几个压电材料的矩阵，记得给电压的时候给对方向就行了

唉，tzhdacy大虾，我正在找做过这个例子的人呢，你有出现过我那种结果吗？我现在什么都试过了，还是不知道哪里出了问题。
