CST mesh type hexahedral problem

When I run Frequency Domain Solver with hexahedral. Simulation stopped and Message showed Materials with magnetic dispersion or magnetic conductivity in port regions are not supported. What ddoes it mean? Thanks!

It means your port is not setup correctly. I've not run (or had access to) CST in a couple months.

Make sure that your port is defined properly. Most common error may be that your port may be overlapping with some other component of structure
