Hello, developers,
I want to export the drag force of particles in DEM simulation, now I set three scalars des_usr_var (12:14) in drag_gs_des.f, but I found that the exported data are all 0 (the following figure). May I ask how this should be handled?
In fact, I have previously referred to the information to export the drag forces directly, which requires “des_explicitly_coupled = False”. After taht, I can get the particle drag force, but the calculation will always fail to converge soon.
Any possible help would be greatly appreciated!
