Hello All:

Does anyone know of a good resource that explains how to define your own equations and relationships between variables in models in COMSOL. For example, how do you specify the relationship between electric currents and temperature or the relationship between resistance and temperature. I cannot seem to figure that out.

Hi

these relations often come via the material characteristics and their respective temperature dependence

Or you might define them as functions I = I0+alpha*(T-T0) + beta*(T-T0)^2 ...

Good luck
