I see the following error:

Error 33498: Maximum number of iterations reached without convergence.


What does it mean and what should I do to fix it?

    This error message is encountered when using an iterative technique such as the MLFMM, FEM/MoM or FEM. It means the iterative solver failed to converge to a solution (the error in the solution is too large to compute reliable results).

     

    Some tips are available for improving convergence for the iterative solvers in FEKO.

    I'm assuming in the User Manual (any part in particular - it's quite big...)?  Is there another forum question that cover these tips?  Sorry - I just don't know where to find them from the comment.

     

    Thanks in advance! :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

    The tips depend on the solution method being used and it is recommended that the model or description of the model is provided so that we can provide appropriate tips.
