i try to simulat a tringular lattice photonic crystal band gap by comsol 5.2a, and i have receive this message : ""Failed to find a solution for the initial parameter.
Maximum number of Newton iterations reached.
There was an error message from the linear solver.
The relative error (3.4e+002) is greater than the relative tolerance.
Returned solution is not converged.""
if any one can help me please .
thanks
