I have a question with regards to the output "Quality of the state" of Type58 as can be seen below. I am using steam (Prameter1 value = 718) for this model and the ideal value should be between 0 (water) and 1 (dry saturated steam). But what I get is strange values ranging from -800 to +999.
The quality of steam ranges from 0 to 1 for steam in the saturation region as you suggest. However for sub-cooled steam, or superheated steam, the quality of the steam isn't defined. So a value less than zero signifies subcooled steam and a value greater than 1 signifies superheated steam. The magnitude of the results above 1 or below zero is irrelevant.
