Please notify the FEKO support team and provide the error number, preferably together with the FEKO input and output files.
Error 48448:
Direct solution is not valid. It is highly recommended to use double precision accuracy (solution settings).
Error 48449:
Large error for the direct solution. The solution is not valid.
