How can i abort DPM calculations from a UDF
 

Does anybody know how can i vanish a parcel from my field in a UDF. How can i use the following structure?

I tried -- p->FATE_ABORTED; But it didn't work typedef enum { FATE_ABORTED=0, FATE_INCOMPLETE, FATE_EVAPORATED, FATE_ESCAPED, /* also includes trapped */ FATE_MAX } Particle_Fate;
