Error Code -108 reported for 935 surfacesError Code -111 reported for 4 surfaces
Error Codes
The following errors were encountered during the computation:
-108 = Total driving moment or total driving force < 0.1. This is to limit the calculation of extremely high safety factors if the driving force is very small (0.1 is an arbitrary number).-111 = safety factor equation did not converge
