请学会使用软件的帮助文件。

CST MWS帮助文件《Waveguide Port Overview》。

Waveguide Ports in Hexahedral Mesh View

Before starting a simulation, every structure must be spatially discretized. The same holds for a waveguide port. For consistency reasons, the same mesh is used for the port as for the structure. Therefore, it might become clear that the dimensions of the port definition must not necessarily be the same as those used for the simulation. The dimensions must be mapped onto the mesh and therefore might change slightly. However, the port dimensions will always be enlarged; they will never shrink. To control how the dimensions are observed by the simulation, you may enter the mesh mode. There, the mapped ports are plotted with a red frame.

Furthermore, for the realization of the waveguide port mode operator in the transient solver, it is necessary to have some equidistantly meshed region in front of the port, namely three mesh steps as shown in the picture on the right. This grid distribution in front of each waveguide port is automatically considered during the mesh generation and cannot be deactivated.

If the above mentioned condition is not automatically fulfilled by the mesh generation, it is useful to apply local mesh settings to achieve an equidistantly meshed region.
