Hey,

I'm trying to impose a particle adhesion critria involving a concept of force balance on a boundary particles on a boundary / wall.
Please let me know if I can compare aerodyamic force and normal force at the boundary to determine if the particle is going to stick or bounce?
Give me a few hints if possible to get this done.

There's an accretion example in the UDF manual. Aerodynamics have very little to do with accretion: it's the particle trajectory & speed combined with particle-wall contact physics that matter.
