Zhenan Li Guest Posts: n/a	Hi, I want to use DEFINE_DPM_BODY_FORCE(particle_body_force, p, i) macro to define electrostatic force acting on a charged particle. I added the electrostatic field (Laplace equation) using UDS. The force is F=E*Q. I think I can get E through C_UDSI_G(c,t,0)[i] If it is correct, how can I connect the scalar gradient with the particle in DPM? Thanks!
