Moddeling change in resistance/conductance due to thermal expansion
Dear Comsol users, Due to temperature a material expands and when it does the electrical resistance of this material also changes. I want to model this in comsol. I added the thermal expansion first,...

Hi Rutger, As far as I know, resistance changes caused by deformation are usually due to geometry changes rather than material properties changes. For exampe a strain gauge that is stretched becomes...

Dear Pieter, You are correct. I formulated my sentence incorrectly. Due to the expansion of the material the resistance of the geometry will increase. However, how do I model this in Comsol?

Hi Rutger, You do not need to add an ALE interface. You just have to switch on 'Include geometric nonlinearity' for the study step. Then the Electric Currents will see the deformed frame. Regards, Henrik
