Possible Memory problem with foam extend 4.0

HenrikJohansson · March 8, 2018, 07:02

Hi

I been analyzing a turbine with MRF, mixing planes, cyclic GGi:s and a real gas fluid. It works well with a coarse mesh.
I have now switched to a more powerfull computer and tested my coarse mesh case. Everything works fine.

So I refined my mesh from 1M cells to 8M for better accuracy.
My mesh have good quality and when running checkMesh -allGeometry -allTopology in openFOAM it shows no error.

But when I do any command(checkMesh, decomposePar, steadyUniversalMRFFoam) in foam extend i get the following error.

From google I get the solution that it has something to do with memory swapping?
My computer have 55GB ram and six Intel i7-3930 Cores and I'm running Ubuntu 16.04.

Code:
