I am trying to generate a ternary diagram of a water/ethanol/ethylene glycol mixture, but it gives me an error for upper bound violation for EG. I have attached the ternary map inputs as well as the error, if someone could please have a look and tell me where they think the problem is.

Thanks for your time

Water/ethanol/ethylene glycol is not a candidate for VLLE.  They are all 100% soluble in each other.  Go for VLE.

In that case it asks for a temperature input, according to what would I select that?

At 1 atm pressure, somewhere between the normal boiling point of ethanol (78.2 C) and ethylene glycol (197.3 C), would be my guess. Where do you want/need the properties to be at?
