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?
