Hi Everyone, my setup here is a deformed surface by displacing along the normals using point attributes computed by a chopnet. No problem for that just for co text.

I then pipe this to a vellumfluid sop.

I have Nothing specific in my dopnet except Vellum source vellum object piped in a vellumsolver

My grains are deformed properly but my purpose was that "strong" spikes / displacement would result in part of the grains to detach a bit like a fluid splash/burst. (I use the particlesfluidsurface sop after solving).

I tried different parameters such as surface tension, viscosity, etc... And for the life of me i cannot have some groups of grains to detach.

Could you guys give me a hint on what to try ?
