Hello,

I am trying to extract the interpolated fluid velocities + cell volume at the current particle position. Anybody experienced in using UDF macros, could you help me to understand what I am doing wrong?

#include "udf.h"

DEFINE_DPM_SCALAR_UPDATE(interp_vel_and_volume,c,t ,init,p)

{
cphase_state_t *cp;
cp = p->cphase;
P_USER_REAL(p,0) = cp->V[0]; /* Interpolated x-velocity */
P_USER_REAL(p,1) = cp->V[1]; /* Interpolated y-velocity */
P_USER_REAL(p,2) = cp->V[2]; /* Interpolated z-velocity */
P_USER_REAL(p,3) = cp->C_VOLUME(TP_CELL(p),TP_CELL_THREAD(p));
}
