helo everyone i have the same probleme, i would like to simulate an airflow around an airfoil i used rhosimplefoam like a solver and when i'm compiling its apear this message:

if someone can help me please it's for my master project, thank you

Dear Mehdi,

I guess your zero conditions 0/k or 0/epsilon are making floating point exception.
make sure internalField of these two files are not equal to zero.

Regards,
Mehdi

thank u for replying, my k and epsilon aren't 0 I did everything, no results. I guess that this solver rhosimplefoam are not for external fluid or there's a mesh errors because I don't have a checkmesh command I have OF 3.0.1
