Using DPM and Eulerian model in Fluent

      Hi

      I notice that the DPM and Eulerian models both having (water+solid phase) have differences in Ansys, for eg in Eulerian model we can use a variety of lift force variations but in DPM we can only use original Saffman model. Why is this? If i want to use a lift force model from Eulerian model in DPM can I do so?

      thanks

      They're different models, the various lift models were added based on the physics need. You can't use an Eulerian model on the DPM without coding it up with a UDF.
