TwoPhaseEulerFoam bed tutorial case crashes in 1.6. Stable in 1.5
The tutorial "bed" for twoPhaseEulerFoam crashes under 1.6. Nu such problem with the 1.5 version.
The problem seems related to turbulence, but I have not pinpointed it further. I am seeing the same behavior with my own work. TwoPhaseEulerFoam-cases which ran under 1.5 are more unstable and crashes frequently in 1.6. I started a thread on the issue at http://www.cfd-online.com/Forums/ope...tml#post238702.

I changed the default value of "E" used in the wall-functions to a more standard value and now this case runs to completion. This change is now in our OpenFOAM-1.6.x git repository.

The same problem I simulated with Fluent and MFIX, which gives similar results, but those of twoPhaseEulerFoam are total different and unphysical concerning the solid-phase velocity field. Has anybody an idea what might be the reason? regards, N.S. |
