I want to insert an electric circuit next a magnetic device to measure the power courant.my model is represented in 3 D, for I notice that the option 'Multi-Turn Coil Domain ' is found only in 2D or 2D axisymmetric.
so my question how can i insert the electric circuit in 3D model?

Hi

use terminal BC to get additional bulk variables for our electric parameters.

Good luck

Hi

Sorry, I see such a node, but you have not given any version, perhaps you need a newer version of COMSOL, as everything was not implemented fully in the first 4.0-4.2 versions

I am using newer version but still i dont know how to couple the electric circuit for magnetic sensors with FEM model of the sensor.

Firstly, if i create the circuit with coil then how can assign the coil in COMSOL.

Secondly, how to create the ODE for the circuit still i am not clear about the ODE?

Thanks in advance

I hope if you use comsol 5 version you can solve this problem because they have multi turn coil in 3D now.

Did you solve the problem of coupling magnetic circuit with FEM? IF so would you please help me to solve the problem....
