CST模擬時的錯誤，幫我看一下

CST模擬時,斷口采用微波源,但是在模擬時不能運行下去,錯誤如下:
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.
我加密了網(wǎng)格也不行,為什么在最開始三個網(wǎng)格里說我是imhomogeneously?

我今天也遇到了這個問題，不知道怎么解決啊新手
希望高手能指點一下
