Summary0002575: Spurious solutions when using reactingFoam with g>0 in parallel.
Description
When running reactingFoam in parallel some spurious modes develop in the velocity when g > 0. The mesh is 2D and regular.

The modes are visible when horizontal splitting is used (either simple or hierarchy split).

The number of modes depends on the number of processors in the horizontal directions.
Steps To Reproduce
When running reactingFoam in parallel some spurious modes develop in the velocity when g > 0. The mesh is 2D and regular.

The modes are visible when horizontal splitting is used (either simple or hierarchy split).

The number of modes depends on the number of processors in the horizontal directions.
Additional InformationThe problem only occurs when g>0 and severe when splitting the domain horizontally.
 
Vertical splitting alone seems fine, with the exception that very minor modes (that seem unimportant) are filtered out in comparison to the single processor solution.
TagsNo tags attached.

Hi,

I didn't manage to upload the results after 3 sec because they are too large.

Please upgrade to OpenFOAM-dev and check if the problem persists, if so upload the updated case.
