Hello.

Now, I want to export the DPM data in a plane(particle velocity, particle location, particle id, particle time when particle is passing at each cell, and cell id which particle is passing).

For this, I've made a UDF code and it was compiled well in Fluent.
However, When I used this UDF in a Sample Trajectories, the message appears :

"Error: received a fatal signal (Segmentation fault).
Error Object: #f"

This error is captured and attached below.

This is the UDF code.

DEFINE_DPM_OUTPUT(PSI_C_method, header, fp, p, t, plane)
{

if(header)
par_fprintf_head(fp, " x y z u v w diameter mass_flow_rate time particle_ID ");

par_fprintf(fp, "%d \n", P_POS(p)[0], P_POS(p)[1], P_POS(p)[2], P_VEL(p)[0], P_VEL(p)[1], P_VEL(p)[2], P_DIAM(p), P_FLOW_RATE(p), P_TIME(p), p->part_id);

}


DPM is steady and no interaction.
Could any one help me, please?
Thank you.
