UDF variable definitions

adubois · December 13, 2016, 01:11

Hi all,

I want to create a udf to write some variables to a data-file (text based to be plotted / analysed outside of fluent). I have some experience with udf's etc but now I wanted to know if there is a full list of variables available in fluent and the arguments needed to call for them. So looking for a list of variables / arguments ... This could be really trivial but I dont seem to find it anywhere.

For example found this,but my question is thus how do you know that N3V_VS is an existing argument for the force you are looking for ..

N3V_VS(Force_viscous,=,F_STORAGE_R_N3V(f,thread,SV _WALL_SHEAR),*,-1.0);

Thanks in advance for the help!

Hi,

you can look in the storage.h file located in your installation folder to see all the variables availables. It might help you.
