I am using comsol's pde equation for electrothermal coupling, currently I want to use the parameters from the material library in the pde equation, how can I achieve this?

Hi,

If the material property does not dependent on temperature, you can use it in a PDE coefficient as mat1.def.Cp, for example, which represents the heat capacity in a material with the name mat1. If there is a temperature dependence, you can define a parameter for the temperature and pass that or a numerical value as an argument for the temperature, when it is not a dependent variable T that you solve for.

Best regards,
