I have added user defined material in Comsol while working on TENG Model, but I am facing following error: "Undefined material property 'epsilonr' required by Charge Conservation 1" I set permittivity value 4 for material. Any suggestion? What am I missing here? Thank you for your help.

Every time I have seen this error it has turned out that I did not, in fact, correctly specify the permittivity.

If you want more help post your (reduced) model.
