Masroor New Member Masroor Join Date: Nov 2015 Posts: 10 Rep Power: 10	Hello experts, I want to write a UDF to set the non-uniform has holdup at inlet of a 3-D cylindrical column. For that I need to use the looping function so that a non-dimensional radial distance (in main equation) can be calculated. I referred an example of DEFINE_PROFILE macro that is about the parabolic velocity, but it is for a 2-D geometry whose inlet is basically an edge. Since I am using a 3-D geometry and here inlet is a face. I need opinion and directions of experts. Thanking you in advance and looking forward to receive a positive and quick response.
