Hi! Ansys Fluent users! I am trying to write a UDF for post-processing. Here I need to access FACE values from the WALL Zone, then put them in my equation, and store that evaluated values for examining the results.
So before I do that I wrote a piece of code (the first code below) wherein I am reading (or accessing) variables from FLUENT which are Cell-based values. Here the code is executed on demand. everything is well, and even results I can plot using Contour or xy plot.
However, when I replace all the Cell-based data access to FACE-based, the Results I get are simple ZERO everywhere on that Face of Wall Zone. I have attached the same Code for FACE-based access (the second code below). Does F_VOF work properly in FLUENT UDF?? And why FACE values are ZERO....??










I would really appreciate very much if someone can help me out with this. Thanks in advance!
