Summary0001758: aachenBomb bug with dynamicMesh and sprayDyMFoam solver
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

Launch the aachenBomb totorial with the sprayDyMFoam solver
TagsNo tags attached.

Anybody is working on this issue ?
Any help would be great !

(I attached a video of a spray showing the problem : after a few time steps, in the first half of the domain the drops follow each other along several straight lines)

Thanks in advance,

Greetings Paul,

There are currently 127 open bug reports here on the bug tracker. Therefore, if you don't at least provide a test case with which this error can be reproduced, this bug report will likely not go any higher in the task list of the developers and/or contributors.

In addition, test cases that use other dynamic mesh mechanisms would help in isolating if the problem has to do only with the automatic refinement mechanism or with dynamic meshing in general.

Best regards,
