Hi,

I have a multiphase flow where solid particles and gas flow vertically in a reactor. I use the Eulerian description of the phases. The gas flows at the inlet and I want that the secondary solid phase stay in the reactor, so it should not leave at the pressure outlet. Is there some way to do it without using a UDF? Or, if it's done using a UDF, can you please help me with that, noting I am only a beginner to using UDFs! In another thread some people suggested using a backflow volume fraction = 1. I don't think this is the right solution.
