Hi Rob,

thank you for your answer.

Unfortunatelly the C_YI(c,t,i) macro does not work with the partially premixed models. I need to use the Get_Pdf_Yi(c,t,i) macro which returns the value of the tabulated mass fraction, and not the one computed with the FGM scalar transport equation.

I can easily get the information in post processing, but I would like to access it also in my UDF
