HI
i have following errormessage in OpenFoam. I donīt understand that error. Maybe someone help me? THANK YOU !!! Code:

Quick answer: This line:
Code:
bounding epsilon, min: 1.8556e+11 max: 1.3527e+11 average: 8.73237e+07 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
