Udf_bodyforce for interacting particle system
I am trying to calculate the body forces on every particle in a discrete phase model problem, where every other particle exerts a certain amount of force on the particle to be analysed. The interaction forces between the particles depend on the relative positions of every particle. Moreover each particle changes with time . Can any one please help me with a macro or anything that will give me the positions of the other particles that is exerting force on the particle to be analysed.
