I had designed a helix antenna with the frequency of 440MH, after computing the model encountered with this error, I'm using FEM method, how can I solve this error and where to find the solution.
You can try the direct sparse solver.
Also see in the Feko User Guide in the appendix:"How to Improve Convergence for the MoM / FEM"
