Molar Fraction Help Needed
 
Hi everybody

I've programed an UDF that writes the mass fraction of a certain specie on every cell of my thread to a file. However, I must do the same thing for the specie's molar fraction, and I just can't reach how to do that. Is there any flow variable macro to do that?I've already looked for such a macro but i haven't found anything!

Really need some help!Thank You All

There is no macro for molar fractions. You will have to calculate the molar fraction from the mass fractions.
