最近,在用CST仿真螺旋天线时遇到这样的问题:
Maximum number of pluse widths simulated,solver stopped.pleased note that the steady state energy criterion has not been reached.
另外一个:
1 propagating mode at port1 is not considered in the time domain calculation! ( 1 mode shares
the same beta with considered mode(1) degeneration ). It might be better to increase the
number of modes at port1.
调整螺旋尺寸时,有时会出现这样的问题。造成结果是方向图是整个绿球或者是s11不准确。
请问如何解决?

也有同样的问题?
你有没有画金属板反射面啊?
第一个问题可以通过改变 solver \ special \ steady state \ Maximun number of pulse
第二个问题是,在端口上又产生了一个传播模式,而你没有考虑,说明不在是单模传播了,如果你不想要这个模式的话,那么说明这个尺寸肯定不能满足你的要求,在改吧!
如果你需要这个模式的话,那么把端口模式的数量增加就行了
