Simple waveguide problem. I make a rectangular block of air, 2 cm x 1 cm x 10 cm surrounded by the default PEC boundaries. Ports at each end. Ports both set to Numeric. Add study -> Boundary Mode Analysis Frequency domain. I set the frequency of the mode analysis and frequency domain to be 10 GHz. Everything else defaults. I click compute. Bang:
Undefined value found.
- Detail: Undefined value found in the equation residual vector.
There are 1 degrees of freedom giving NaN/Inf in the vector for the variable comp1.emw.S2x.
at coordinates: (0,0,0), ...
- Feature: Stationary Solver 1 (sol1/s1)
What's this undefined value? If I make one of the ports rectangular, no error. But both numeric, Undefined value. What's the deal here? Obviously I'm missing something obvious with regard to how boundary mode analysis and numeric ports work. What is it? The docs on this topic (as usual) are pretty thin.
