UDF-DPM
 

Hi,

I am using UDF to define the body force for the particles in DPM.

DEFINE_DPM_BODY_FORCE(particle_body_force, p, i)

How can I get the current location of a particle in this macro?

Can I use C_CENTROID(x, c, t)?

Thanks,

Hi,

C_CENTROID returns a cell center location around a particle.

About a particle location , you have to use this one "p->state.pos[0]".

This zero is position vector.
