| Summary | 0001665: multiphaseInterFoam regression | ||||
| Description | multiphaseInterFoam-2.3.x is very unstable if rotation axis is not aligned with wall cells. | ||||
| Steps To Reproduce | 1) Run the modified, attached tutorial using "Allrun" 2) Changing the rotation axis in fvOptions to be aligned with the geometry, i.e. to ( 1 0 6 ) and running again, multiphaseInterFoam will not crash. | ||||
| Additional Information | Crashes in 2.3.x-16e20e833934. Case runs without problems in 2.3.0. This is the most simple test case I managed to come up with. It is also valid and reproducable for complex geometries. | ||||

When you say "multiphaseInterFoam-2.3.x is very unstable" what is the mode of failure? Does the phase-fraction go unbounded? How long does it run for? |

Henry, it does not even complete the first iteration. ---- [...] --> FOAM FATAL ERROR: Continuity error cannot be removed by adjusting the outflow. Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow. Total flux : 3.78634823e-05 Specified mass inflow : 1.48335713 Specified mass outflow : 1.48335713 Adjustable mass outflow : 0 From function adjustPhi(surfaceScalarField&, const volVectorField&,volScalarField&) in file cfdTools/general/adjustPhi/adjustPhi.C at line 118.

This is not an issue with stability but with the adjustPhi check. I have fixed the problem and running your case. I will push the fix shortly. |
