The mixture of 32,5%wt urea with water is called AUS32 and it is liquid at standard conditions (1 bar, 298 K), but in Hysys this mixture is predicted as liquid-solid and a lot of urea doesn't dissolve in water (so it is in a solid phase).
How can I adjust the value of solubility of urea in water, fixing also the dependence of solubility from temperature?
