Hello,
I simulated a straight pipe like the one you see in the figure below with uniform bc's for U, k and epsilon and everything went fine. I then used the same bc's and configuration files to simulate a bend like the one in figure below but I get 'floating point exception' and the simulation crashes before the first iteration. Can anyone give me a hint on what's happening here? Best, Z |

If it crashes before the 1st iteration something is definitely wrong with your setup or, more likely, the new mesh. Posting the actual log file would help. Run checkMesh -allTopology -allGeometry as well to convince yourself there aren't any obvious errors in the grid.
All the best, A |
