Torque on DPM
 

Hi all, Hope this question is not too basic.

I'm trying to setup a 2D simulation which include forces on particles flowing in a liquid and I need to include the torques generated on the particles as they approach a solid surface.

I've read some physics books but I'm still not sure if the torques generated are forces or momentum sources and how I shall include them in the force balance of the particles.

Can someone give me some insight?

Thanks
