Hi everyone,

I have been trying to run the pimpleFoam into my propeller case but there has been some error on executing the pimpleFoam after some minutes of execution.

Floating point exception (core dumped)

Also, on executing the checkMesh, I got
***Max skewness = 7.68338, 60 highly skew faces

I have been trying to run it in both serial and parallel but non of this work. Same problem reoccur.


what could be the possible error to this? I don't know whether the problem arise because of skewness or something else.


I am working in a project and there is no one to help me in OpenFOAM. This is only one option where I could ask for some help.


Thank you.
