Floating point exception in rhoSimpleFoam
 

Hello,
Since I couldn't find anything anywhere about this.My problem is that I have a simulation (file is attached), that does run under specific mesh settings. The problem is that it runs only to a certain extent and then brings up a floating pint exception. My flow is pressure driven and my inlet velocity increases with every iteration until it breaks the simulation. I don't know what to do anymore or what screws to turn so it works out. Could anybody give me any advice on this?
