Hello,

 

I'm studying particle impinging a wall where the criteria for particle sticking to a wall is the moment (F*d) on each particle at the wall as a function of drag force and velocity of particle at contact. 

I see that I can use DEFINE_DPM_BC for this.

 

Since I input a custom drag force model I would need DEFINE_DPM_DRAG, my question is about how I can import the drag force in this udf to my DEFINE_DPM_BC udf so I can calculate the moment on each particle at the wall.

 

Is there a way I can use both of these udfs under the same header and make it a whole different udf with multiple macros?

This whole criteria is for ansys to decide if the particles sticks or bounces off from the wall

Thanks,

Kiran

What are you doing with DEFINE_DPM_BC to cause the particle to stick?
