Hello,

I'm trying to perform Biodiesel simulation in COCO and to do that i need to use NRTL model to the liquid phase. I have some doubts about the parameters to insert in "Property pack definition". I saw in Help the definition concerning "tau ij" which has the interaction parameters (gij-gii), (gji-gjj). Looking in the windown "interaction parameters" there are two possibilities of parameters, the "NRTL interaction" and " NRTL interaction temperature dependence", so, to me there is a divergency (or missing some equation in help) between the help definition about NRTL model and the input parameters in the "Property pack definition, Interaction parameter". Can you explain that?

Thanks,

Gonçalves
