I know how to create isosurface or line, but not a curved line. thanks a lot antonietta

Could I set a dpm trap boundary condition on the clipped surface?

Hi,
I need to know the shortest distance of wall from the particle location. I know I can use C_WALL_DIST(c,t) this, but how do I connect from:
px=P_POS(p)[0] ;
py=P_POS(p)[1] ;
pz=P_POS(p)[2] ;
??
