Hey Guys,

I'm trying to simulate a case where the particles in a domain free fall from a height onto a surface within the domain to study particle build-up/ accumulation.

I have used wall-film BC for this and the problem is that the wall-film BC is only used to see particle deposits of 5 microns.
I want to see more of the particle accumulation as a function of time.

What options do I have and what do you think I've missed?
Can I achieve my objective by using UDFs in Fluent?
Please help me understand how I can go ahead.

Thanks in advance,
KP
