Hi all,

I have written a solver which does some additional miscellaneous calculations not directly connected to the flow field.

Normally, this works fine, but when I try to run the model in parallel, OpenFoam throws a gigantic error. I have isolated the error and it emanates from the "exp()" function which is used in several lines.

I will not bother you with the entire error but it starts with the following lines:

[0] #0[2] #0  [1] #0  Foam::error::printStack(Foam::Ostream&)  Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&) at ??:?

Has anyone experienced this before?

Thanks in advance,

Hi Robin,

I changed nothing. The error is gone now... Oh the miracles of programming
