Hello,
I'm simulating a simple geometry which is wetted by rain from above. For this I use the reactingParcelFilmFoam solver and got everything running without rain.

But when I turn the rain on, the simulation crashes, when the parcels hit the bottom and jump back into the flowfield.

Is there a Boundary condition, which is permeable for the parcels (so the rain can fall through the Bottom)?

in reactingCloud1Properties you have to define what will happen to particles at the boundaries.
escape or rebound for example. It seems you have defined rebound at this patch.

thanks, seems working!
