  Can we enter the properties of water at two different pressures at varying temperatures in FLUENT?nI am working on a problem in which there are two different streams of fluid at two different pressure and one stream will undergo a phase change. nFLUENT allows the user to enter properties only in terms of temperature by using piecewise linear. nIs there a way where I can specify it with respect to pressure and temperature?.

  Hello, nYes. you can use DEFINE_PROPERTY UDF to customize your material properties.nBe careful about Density. For compressible liquid, if you want to vary the density with pressure, then you will need to provide a UDF for speed of sound as well. The link below explains this UDF in more details.nRegards,nSDn
