Hi,
I'm trying to use interDyMFoam for the simulation of water entry. The geometry is similar to the movingConeTopo tutorial, with different shapes and some more grid refinement, plus a gamma field. Anyway, the solution seems to chug along nicely until the interface interacts with the cell addition zone (or removal? - I haven't checked that, as the removal zone was under the water). It seems that the gamma fluxes might get swapped (phase 1 for phase 2, or vice versa) in those cells. With a density ratio of 1, this doesn't cause stability issues, but when some quantity of water gets made into air (I think), that it generates pd spikes, eventually leading to a crash.

Has anyone else experienced this? If so, is there an easy enough fix?

Thanks,
Sean McIntyre
