Hi there I am a final year mechanical engineering student currently working on my thesis. The study is on the erosion rate of an abrasive particle air jet (like a water jet cutter but with air) The model is in an attachment. the sides are lids at atm. pressure and the inlet pressure is at 8 Bar, the nozzle walls are real walls. I manage to simulate the air flow and include a particle study, however I have a bit of a problem.

When I include the particle study to see the erosion on the plate which is beneath the nozzle, I include a wall condition, however it seems that the only property of the material it considers is the density of the material, is there a way in which it can differentiate say if it were glass or aluminium for example?
