udf to access Premixed-G-Equation variable
 

hi,

I currently require to access the premixed-g-equation variable via a udf and am unsure how to go about this, I was wondering if anybody can help shed any light on the problem?

A user on the forum has already kindly helped me to access the mixture fraction species concentrations but it turns out I don't actually need them...

Does anybody know how to access the additional variables not listed in the udf user guide? - I thought about writing a data file to do this but have no clue how to even get started...

any help is greatly appreciated!!!
