COMSOL: How to relate terminals in electrical current?

Click For Summary
SUMMARY

The discussion focuses on using COMSOL Multiphysics to relate multiple terminals in a 2D electrical circuit simulation. The user aims to simulate the capacitance between winding wires of a coil, necessitating the correct selection of boundary conditions for terminals and grounds. It is emphasized that in a serial circuit configuration, terminals cannot share the same potential, thus requiring a method to relate them effectively.

Simulation of the capacity between winding wire of a coil using 2D geometry.
hello, i have a problem in comsol multiphysics, i want to relate many terminals to each other to buid a current circuit in 2D geometry.
I was thinking to simulate the capacity between winding wire of a coil. So, I have to choose boundary conditions in the winding wire which are Terminals and grounds. For the terminals, I can't put the same potential in all wire because it is a serial circuit (coil) So, I have to relate terminals to each other.
