pec boundary symmetry
Ok good. Is that mean that I have to specify "open (add space)" for the radiation side(s) ??
I'm simulating simple antenna structures using CST. The antenna is kind of slot or some other shapes as well. Anyway, I'm getting two kind of errors, and I don't know exactly what they means? and why they appear? and how to overcome this problem.
1- Some PEC material is touching the boundry ! This may lead to inaccurate farfield results. Please check your structure.
I have copper not PEC. And it is touching the edge from the port side.
2- Some higher propagation modes at port 1 are not considered in time domain caculations. This possibly leads to an inaccurate energy balance. Consider to reduce port size or decrease the upper frequency limit.
