Dear Dr Rob,

Water-liquid density is specified as temperature dependent but density of water-vapor is a constant. Oh, it's said that density of water-vapor must be set as real gas or something. Otherwise it's not conform to reality and hence solver may encounter numerical problems. Is it right? 

And I found large pressure in the domain. Can it can demonstrate it to some extent?
