I see the following error:

Error 4986: No tetrahedral faces were found on the FEM boundary for the modal port with name <name>.


What does it mean and what should I do to fix it?

    This error could occur when using the FEM together with FEM modal port excitations and the mesh elements to which the port is applied are not set to dielectric. For example, this error would be given when applying a FEM modal port to a PEC surface.
