Can the body force UDF load two different kind of body force?

      Hello,

      Can the body force UDF load two different kind of body force in the DPM UDF interface? Because I want to add two different body forces through the body force UDF, I need to analyze the effect of two different kind of body force.

      Thanks.

      No, there's only one hook. Nothing stopping the UDF from summing the force components from multiple causes though.

      Thank you,Mr Rob.

      If I sum the force components in UDF,how can I output each kind of force and analyze?

      User Defined Memory, one for each component. The solver uses the sum in the trajectory calculation but each UDM records one single component.

      You need to sum to a single return but you can store in Particle User Vars to differentiate between both.
