Thank you for a great program!
But I have encounter problems when changing compounds in existing model, for example from R134A to R407C.
The Model works fine with the original compound but fails when changing to a new compound?
usually the molar flow etc. shows null values. Is there something wrong I am doing when changing the compounds?
So the only way to fix this is to build up a new model with the new compound.
I am using CoolProp package.
Also I have an issue with the info. screen, where message on script data updated successfully is constantly running?
