Hey everyone,


I'm currently trying to model clogging in a pipe caused by particle collisions on the wall. I have seen papers where they implement a strategy of somehow changing cells in a mesh from fluid to solid, and vice-versa in simulating fouling in diesel exhausts.

The only problem is, they do not at all specify how they change cells in a mesh from fluid to solid. My only idea at the moment is trying to utilise the DEFINE_PROFILE UDF in Fluent to change the porosity, but I doubt it'll work for individual faces.


Is there anyway to change individual cells in FLUENT from fluid to solid, or externally using ICEM and the like?
