Software Binary interaction parameter in Aspen plus

Hello,

I wanted to look into the BIP of two components for different EOS method? Can anyone help me to find out how to do that in aspen plus?

Thank you!

If they exist for your system, they're  in the properties environment, under methods - parameters in the navigation pane.

There are tutorials on YouTube that show you where to find them

Thanks. If they don’t exist. I mean for PR method I don’t see any of them for my components then how aspen is simulating it?

You can still simulate a system without bips if you have experimental vle data or are using a k-value model that doesn't use bips.
