Summary0001665: multiphaseInterFoam regression
DescriptionmultiphaseInterFoam-2.3.x is very unstable if rotation axis is not aligned with wall cells.
Steps To Reproduce1) 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 InformationCrashes 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.
TagsNo tags attached.

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?

it does not even complete the first iteration.


Continuity error cannot be removed by adjusting the outflow.
Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.

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.
