Hello All,

I am having a problem with running a case in parallel. I am trying to run the case on 4 cores, with porousSimpleFoam as my solver. I am getting the following error. The case is getting decomposed, and also runs potentialFoam. But as soon as it starts the calculation, then, I get this error. I tried to run it not in parallel, and it works perfectly. I tried to check with one of my other case of porousSimpleFoam, and that works too, in parallel and in series. I don't understand the problem.

Does anyone have an idea???

Can you give us the top part of the error message? Also, what command are you using to run in parallel?

[renyun0511]

hi, Dhruv and danishdude,
I am with the same problem when I use MRFSimpleFoam (OpenFOAM-1.5-dev) in parallel running. The command and steps I adopted are:

How can you solve this problem?

I only can speculate, but the final residual of Ux etc. are a bit to coarse. Adjust the linear solver setting in order to obtain a better residual. Probably, this might solve your problem. I dosent seems to be mpi problem.
