Skew factor of decomposeParDict

jms · May 23, 2011, 09:04

Dear all,

Can anyone tell me which value to introduce in "delta" in decomposeParDict? Is it the cell skew factor given while doing "checkMesh"? Otherwise, what is it?
I am doing simulations in a 2D airfoil and while running them in parallel mode I get instabilities and the solution for Cl & Cd starts to diverge.

Thanks in advance.

Regards,

José

Hi José,

Do you have any info on that "delta" parameter? I think it is a global tolerance for the subdomain geometry but I'm not sure... Can anyone explain its signification?

Thank you!
Pascal
