Error with rhoCentralfoam

gns4566 · May 10, 2020, 10:47

Dear

I would like to solve supersonic flow for with rhoCentralfoam

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....

Can anyone help this?

I'm not familar with openfoam

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

Thank you for replying to me

I'm wodering what do you mean "toleranece"?

Do you mean fvsolution? right?

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

and also I have same error....

and I follow the instruction, I also get a same error message

please help me..
