Summary0001928: aachenBomb bug with sprayDyMFoam
DescriptionWhen I add a dynamic mesh option to the aachenBomb tutotial, the drops start to behave really weirdly : it goes straights forward...

Originally I noticed this problem with a classic spray injection of n-heptane droplets. At the beginning, everything looks ok but as soon as the domain is refined during the simulation, the droplets behave strangely : it follows straight lines.

It is closely linked to the automatic refinement because when I turn it off and design a fine mesh from the very beginning instead, the bug doesn't appear anymore. Also because this bug appear just after the mesh refinement.
Steps To ReproduceAdd a dynamicMeshDict file in the constant directory of the aachenBomb totorial.

Modify the controlDict file to use the sprayDyMFoam solver


Run the aachenBomb new case.
TagsNo tags attached.

It is likely that this will take significant effort to fix so unless you or someone else has the time to work on it we will need to seek sponsorship.

I've already spent some time on this issue without being able to figure out what the problem is, and unfortunately I won't have much more time to work on it...

It is likely that this problem relates to the pressure equation issue reported here: http://www.openfoam.org/mantisbt/view.php?id=2000

Could you test this change in OpenFOAM-3.0.x/dev and report back?
