Electrical Circuit (cir) interface and Time Dependent Study

Hello,

I am working with a 3D model in Comsol 4.2a. I can successfully run the eigen study, frequency domain study and time dependent study.

But when I introduce the Electrical Circuit interface instead of directly applying boundary conditions to the model itself, I dont get the same results with my Time Dependent study as I get without the circuit interface. In fact, the plots for potential and displacement are all zeroes.

Is there a parameter I am missing out on with respect to using the Electrical Circuit interface? Or could there be some other issue? Any ideas?

Thank you.

Sneha

Hi

probably you have not managed to couple the two physics, CIR can only couple to a large model via terminals and the appropriate UI or IU links, check it out on the Model library examples

Good luck
