Floating point exception after changing from straight pipe to bend

Zen · January 25, 2016, 10:39

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
