Add a new material / fluid

Hi,

 

I want to add a new fluid dedicated for cooling (such as glycol water), in order to test it with the same cooling circuit and compare its efficiency with the normal water defined by Altair.

 

Unfortunately, I can't find all the characteristics of the fluid, which Altair requires, such as first/second order temperature coefficient for density, viscosity, ...

 

Please, do you know where I can find this information? I have searched in the literature but did not find all the necessary information.

 

Thank you in advance.
