Hello, I wanted to trap particles as soon as certain condition is fullfilled (not on wall). For example, trapping particles on dis=2e-3 m where dis= distance from the wall and particle centre.

regards, HK

You should be able to use the variable P_POS(p)[i] which is the position of the particle, p. The variable, i is the direction, x=0, y=1, z=2. (This is for Fluent 6.2, it was different in v6.1).

If particle position > dis then return PATH_END.

You can even increment the variable for the number of particles trapped, gvr_trapped?. Look for it in the dpm.h header file, if it is of interest. Good luck.
