I have problems changing the compunds in a existing model?

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?

When you add a new component after removing the existing component from a simulation, you must check the composition after adding or removing the compound. Generally, after the compound gets removed and the new compound gets added to an existing simulation, the mole fraction of the newly added compound remains zero because of which the molar flow and other shows null values. So after adding the new compound, make sure that the mole fraction is not zero.

Thank you for the answer, it seams reassembly. I tried to make the mol fraction not equal to zero. But the program still seams not to accept this update? Maybe the property package CooProp is not working fort R407C? When using Soave_Redlich-Kwong method I could receive a solution? regards /Svante
