Thank you Matt. Yes, I am getting the "CellDM" from the DMSwarm.
1. I have recently overhauled this functionality because it was not flexible enough for the plasma simulation we do. Thus main and release work differently. Nice to hear that. Should I move to main? 2. I assume you are using release You are correct. 3. In both main and release, if you change the coordinates of your CellDM mesh, you need to rebin the particles. The easiest way to do this is to call DMSwarmMigrate(sw, PETSC_FALSE). What do you mean by rebin?
