Hello CFDEM users,
I want to output different forces acting on particles such as normal contact force , normal damping force, tangential contact force, tangential damping force, drag force, pressure gradient force etc in xyz directions and gravity force as well. Also I would like to output these forces acting on wall (stl boundary). I would appreciate if somebody guide me in preparing the input script needed to output these.
With Best Regards,
Manoj L Das

Hi,
Hi,
fluid forces acting on the the particles are lumped together to the dragforce variable which can be dumped via th liggghts in.* file. (there was a discussion on that latley in the forum). When you are interested in each force you might go to the dragmodel directly and add some code for an output of the force.
an example for forces acting on stl would be in the Finnie wear model.
Cheers,
Chris
