Hello

I tried to set up a rough wall for a run with buoyantSimpleFoam using the syntax:

wall
{
type mutRoughWallFunction;
Ks uniform 0.005;
Cs uniform 0.5;
value uniform 0;
}

and I got this error message after starting buoyantSimpleFoam:

Floating point exception

Would someone know what the problem is? Everything works fine with mutWallFunction.

I also tried to use mutRoughWallFunction in the hotroom tutorial for buoyantSimpleFoam but I got the same error message. Is this a bug or my lack of understanding of the use of mutRoughWallFunction?

Cheers

Please try this

Code:
export FOAM_SIGFPE=false
Code:
unset FOAM_SIGFPE
