Electromagnetic Waves physics / Eigenfrequency study / Convergence problem

Please login with a confirmed email address before reporting spam

Dears,

I am trying to simulate electromagntic waves physics / eigenfrequency study. Unfortunately the solution doesn't converge from the first iteration, I get this message "Explicit-Orthonormal null-space function used. Nonsymmetric eigenvalue solver Iter ErrEst Nconv"

What could be the reasons of solution non-convergance?

Thanks
