| Summary | 0001724: Robustness of SST | ||||
| Description | A simulation of the '2D NASA Wall-Mounted Hump Separated Flow Validation Case' crashed due to an issue in kOmegaSST::F1(const volScalarField& CDkOmega) and kOmegaSST::F2(). I didn't investigate further but replacing sqrt(k_) with sqrt(max(k_,kMin_)) in both functions solved the issue. | ||||

I would need to spend a bit more time on the overflow limiters; I am guessing that the issue is with overflow rather than a start-up problem with k = 0. Could you supply the test-case to reproduce the problem here? |

CFD setup does not match the real setup but it should help to identify the problem. Case was made for simpleFoam |
|
|
It's probably necessary to set the relaxation of k/omega to 0.5 |
|
|
This case runs OK in OpenFOAM-dev. I am adding the k limiters from dev to 2.4.x and will push after testing. |

Thanks. |
