Material temperature dependent properties

Please login with a confirmed email address before reporting spam

Hello, I am trying to solve a phase change problem and thereby the properties such as density, conductivity, specific heat are temperature dependant. I input them as piece wise functions with smoothing parameters to get appropriate properties at defined temperatures. I solve it using a Laminar flow - Heat transfer non-isothermal coupling. After getting the results, I checked the properties, and they don't vary with temperature in the results. I would like to know if I am making a mistake or I am missing something.

The problem I am solving is practically imitating a conference paper titled "Natural Convection Driven Melting of Phase Change Material: Comparison of Two Methods". Could anyone help me here

Regards Sai Phani Kiran
