Hello,nIf it is a temperature vs. property type of data, yes - you might want to read it as a look-up table in Fluent. You will need to write a UDF for this (depending on how your data is organized).nIf you are working with a multiphase problem, then you will need to attach a material for each phase in Fluent. You could use the same material of different one. Depending on how you call. Generally, the property variation across a liquid and its gas phase is large and you might want to be careful when using a single fluid for both these phases. Also, the latent heat is estimated based on the standard values of enthalpy. You want to be careful with this as well. nJust curious - why are you not using the Methane properties in the Fluent database?nThank you.nKarthiknn
