StoneCFD727 is on a distinguished road
HI
i have following errormessage in OpenFoam. I donīt understand that error. Maybe someone help me? THANK YOU !!!

Quick answer: This line:
Code:
bounding epsilon, min: -1.8556e+11 max: 1.3527e+11 average: -8.73237e+07
is giving the indication that something very non-physical is happening.

The crash occurred somewhere inside the method "calcReciprocalD", which I suspect does some matrix operations, which may require inverting values.... and it's possible that it tried to invert a value of zero, hence the sigFpe (signal floating point exception).

If you still have this problem and want a better answer, then please follow the instructions given here: How to give enough info to get help
