HI,

I am using COMSOL Multiphysics 5.4.0.388. Working with Heat trasfer and phase change with Laminar flow. I tried to defined a temperature-dependent heat capacity using a piecwise function for a phase cahneg material (solid and liquid phase). The argument is T and defined the units of the argument and function as K and J/(kgK), respectively. For solid and liquidn material I named the Cp as Cp_solid and Cp_liquid respectively. However when I enter Cp_solid(T) in the material content section it turns orange and while computing it shows error.

Unefined variable eoor.

Any suggestions will be quiet helpful.
