Harmonic Analysis under electromagnetic simulation
 

Dear All,

I have created a box geometry in ANSYS APDL. I used HF119 element and meshed its volume. In that 2 opposite faces are assigned with electric wall boundary and the other 2 opposite faces are assigned as Port-1 and Port-2.

But when I writes to find out its s-parameter command i.e., /sparm,1,2 then it gives the following error

"The eigen field at the port 1 is not found".

Please help to solve it out.
