parallel running openFoam-1.5-dev

hi everybody

I am running a 3d simulation of wave boundary layer flow around a cylinder over a flat bed. the domain has approximately 2 million cells.
on a single processor is running without problems but when i run it in parallel it blows up.
i am using a modified turbFoam solver and komega wilcox 2006 turbulence model.

i am running other cases with the same solver without problems.

Does anybody have an idea?

cheers

Hi Luca,

what is the platform that you are running on? can you post your running script here?

Hi

I think the problem was simply that when running in parallel I was running for a much longer time period so my case would break anyway in the single processor running.

How does it work? should I delete this thread???

Hi, yes you could do so if you wish.
