how to transfer (x,y,z) to (i,j,k)
Is there any way to know a given point belong to which control volume or (i,j,k) if we know the physical coordinates (x,y,z) of this point?

Hi pl457156427,
You do not specify which code you need the information for. For CFX4.3, CHECK THE MANUAL on Utility routine FXYZ page 3466 Regards Jan 
the output of Lagrangian tracking model
Hi, everybody: I want to use the function of Lagrange particle tracking in Tascflow 2.10 to get the (i,j,k) position of the particle at every iteration, but the system can output the phisical coordinate (x,y,z) only, so I want to transfer them to (i,j,k), I feel it quite difficult.
Or is it possible to output (i,j,k) by a user subroutine at every iteration? could you give me some advice? thanks in advance! huge
