I am trying to get the mass/mole fractions, temperature etc. from the PDF table within Fluent for a given fmean (Mixture fraction) with a UDF. Currently, it is very easy to get the information I need when it is based on the cell's mixture fraction. However, what I want to do is to get the PDF mixture information independent of the cell, and by giving the fmean, (and whatever else I need such as the fvar or progress variable).

Is this possible?

I found some possible functions within the pdf_table.h file, such as the pdf_interp_2d() function. But there is no documentation on how to use it.
