I tried a stress strain FISH code from the FISH UDEC 6 manual on my Voronoi model for UCS test but when I try to run it, the UDEC crashes and closes. I have sent the picture below. The code and the result. Can anyone tell me how to solve this problem? Thank you.
This case, crash error is due to a dividing 0 problem. I would suggest that you may start with a simple and small size problem to test the FISH you wrote before you actually using it in a real and complicated one.
