      Try the following: 1 – Running double precision 2 – If already running double precision, try increasing the solver memory allocation factor from 1 to 1.2 3 – If the above suggestions don’t work, try using the “Essential” option on the backups 4 – If the above doesn’t work, try not writing backups, but instead just use the temporary res file that’s written as the final res file.
