thermodynamic properties of water in simulink

I am trying to simulate an absorption chiller in simulink and I need to access thermodynamic properties of water.

I tried matlab function blocks containing matlab codes available for water but I got error.

can anyone help me about that?

Sounds like a perfect application for using a table look-up.

For a function of two variables, simulink has a "2-D Lookup Table" block that you can use for a single output parameter. You simply have to build a separate table for each parameter you want to look up.
