So, I write UDF that let me track velocity (U,V,W) and positions of every particle that touch the bottom. But, Now I want to have the ID of these particles ! I don't know which symbol to use for such stuff : Herein is the line : fprintf (f2, "%f %f %f %f %f %f %e \n",x,y,z,velpu,velpv,velpw,P_INJ_ID(P_INJECTION(p ))); So it gave me the x,y,z,u,v,w but it gave me 0 for the ID !!! I suppose P_INJ_ID(P_Injection(p) isn't the right one ??? Help please Thanks
