| Summary | 0003353: reacting*EulerFoam crashes when one field is initially patched with 0 phase fraction | ||||
| Description | When one of the fields is initially patched with 0 alpha, reacting(TwoPhase/MultiPhase)EulerFoam crashes right after the pimple loop on entry into the turbulence object, if one selects kEpsilon or kOmegaSST. If the field is patched with a small positive value (0.001) instead of 0, the solver runs in the beginning but eventually crashes. Attached is a simple test case with reactingMultiphaseEulerFoam. Allrun1 replicates the first behaviour and Allrun2, the second. It is a simple two-phase test case (air and water) of a gas-stirred cylindrical tank initially half-filled with water and air is injected through a small nozzle at the centre of the bottom patch. | ||||
