Faliure to calculate message

[wayne13]

I'm a new user. Tried to set up simple hydrocarbon flash or load example simulations. Get the same error message

Failed to calculate enthalpy for phase Vapor: CalcSinglePhaseProp failed: Failed to set enthalpy: Undefined or unsupported property: enthalpy

It sounds like the property package you are using does not support enthalpy. Which property package are you using?

[jasper]

Can you attach your document? Or specify which examples are you trying and what you are doing to get this message?

i have attached file

You have set the temperature of the flash unit to -459.67 F = 0 K. Try a positive temperature?

I did and received same message that enthalpy calculation failed

[jasper]

If I set temperature to 0 C it simply solves. Send me the fsd with the changed temperature so that I can check?

Thanks.
