Add a "sink term" in the cells near the wall surfaces in Eulerian approach
 

Hello everybody.

I want to simulate particles with Eulerian method by using Fluent. For Eulerian approach, I need to add the particle deposition onto wall surfaces as the boundary conditions. Since Fluent has no such function, this should be done by compiling a UDF. The basic idea is to add one "sink" term in the cells near the wall surfaces, and "sink" is caused due to the deposition.
I have read many papers and they use such a UDF when the use Eulerian method. So I am wondering if anybody here have this UDF or can provide some hint, how can I implement this UDF.

Thanks in advance for your support.
