haijj Guest Posts: n/a	hi, everyone~~~ in many simulations for gas-solid flows, the restituition coefficient (e) is always treated as a constant. But some researchers considered that e was the function of voidage, so I want to know how to modify the restitution coefficient using UDF. I check the help files provided by Fluent, but cannot find the solution. Could anybody help me? thanks very much~~~~
