Well according to your stacktrace the function pow fails. Why that is I don't know. Either it became undefined (for instance with something like pow(-1,0.5) - square root of a negative) or you got an overflow because the number became to big. Have a look at all your expressions that use pow and see what could have gone wrong (mathematically speaking)

Hi,
I think I am getting a similar pow error. I have not had much experience with OpenFOAM. Could you please explain to me the meaning of this error and if possible how I should try to resolve it. Code:

There also is an explanation on the meaning of stack-traces on openfoamwiki.net
