CST模拟时的错误，帮我看一下

CST模拟时,断口采用微波源,但是在模拟时不能运行下去,错误如下:
mode caculation for port 1:
Pass 1 succssfully completed.
Adaptive port meshing finished.
Port 1 is imhomogenously filled within the first 3 mesh cells.Can not start solver.
Error in caculating solver matrix
Solver run aborted.
我加密了网格也不行,为什么在最开始三个网格里说我是imhomogeneously?

我今天也遇到了这个问题，不知道怎么解决啊新手
希望高手能指点一下
