Beginner help, coordinate udf with output file
Join Date: Feb 2014

Hi, I am a beginner in both Fluent and C++.
I am trying to write a UDF for my project, it is a 2D axi-symmetric VOF model for a droplet impact; see link at the end of the post for the domain. The symmetry axis is my x axis and the wall my y axis.
The UDF will be used to calculate droplet height and the wall contact radius at every time step.
I need to find the coordinates of two cells at each time step. Both cells will have a volume fraction of between 0 and 1 (they lie at the interface).
One of the cells will have an x coordinate of 0, the other a y coordinate of 0.
The output file must contain the time step number, current time progressed, the x and then the y coordinates.
I am sure my UDF is not correct, I am unsure whether I have used suitable macros for the task, so would like advice on what I have not included or what needs changing.
If possible please can you explain in layman's terms.
Thanks in advance
