liliana Member Liliana de Luca Xavier Augusto Join Date: Feb 2013 Posts: 69 Rep Power: 13	Hi all, I am simulating a situation where I have a particle travelling in a fluid. The gap where the fluid flows is too small, and the particle size became important in this case. Does anyone know how can I use an UDF to consider the particle size? I would be an UDF to make the collision between the particle and the boundary when the distance between the "point" (particle in DPM) is equal or smaller than the diameter of the particle. Thanks!
