Foam particles keep falling through

[simone_nastasi]

Hi, I got a pretty simple simulation of a tub getting filled with water.
I did the sim and added the foam with resimulation. No matter what some foam is falling out.
The tub geometry seems perfect - stl check says it's ok, mesh cleaner too.
The problem seems worse if I make the foam variaton large bigger. Any help? Should I upload the scene? Phoenix for max 5.20.02

Hi,

Sure you can send the scene to support or upload it here. If it is in MAX I'll take look.
