Hey all,

I wrote a UDF using DPM_SCALAR_UPDATE macro,

DEFINE_DPM_SCALAR_UPDATE(part,c,t,initialize,p)
{
.
.
.
C_CENTROID(pvct,c,t);
.
.
begin_c_loop(c0,tin)
{
c_face_loop(c0,tin,n)
{
xu[0]=0.,xu[1]=0.,Lcf=0.;
f=C_FACE(c0,tin,n);
tf=C_FACE_THREAD(c0,tin,n);
F_AREA(cface,f,tf);
Lcf=0.5*(NV_MAG(cface));
F_CENTROID(xu,f,tf);
r0=sqrt(pow((pvct[0]-xu[0]),2)+pow((pvct[1]-xu[1]),2));
if (r0<=Lcf)
{
C_UDMI(c,t,0)+=P_MASS(p);
}
}
}
end_c_loop(c0,tin);
.
.
.
}

Whenever I am running this UDF in parallel, the values for "cface" and "xu" become zero. If not parallel though, they get the correct values regarding to the cell faces. IF anyone can help me how to take care of it while running parallel, it is highly appreciated.

Thanks
