Temperature Dependence / Material Properties

Hi All,

I notice that COMSOL has several built in materials with properties defined as a function of temperature (or any other input variable for that matter).

As an example, in Laminar Flow physics, the fluid density can often be found as rho(T[1/K])[kg/m^3], indicating a function of temperature.

I was wondering if there is any way to see what sort of function is being used to define density via temperature?

I am aware you can always input a user defined density, and even your own temperature dependent density function. But I was curious if there is any way to see what COMSOL is doing behind the scenes.

Thanks.
