and Turbulence model is Spalart-Allmars model


when I running the rhocentralFoam


I get this error. I attached it



I don't know what is the problem....

Error Floating point exception

You can check more about FPE over this thread, but it actually occurs with a illegal mathematical operation. You may have to look at your mesh and check for the problem.

If doesnt work, try to play with tolerances. I would recommend rhoPimpleFoam, which is more stable, atleast in v7.

Sometimes it can also occur with a wedge where the cells collapse. You can unset FOAM_SIGFPE if requires

Do you mean fvsolution? right?


and Right now, to solve the problem I use laminar model to find out what is problem..
