Circuit coupling

Circuit coupling
Browse model files — Download zip archive

Quick start

To run the model, open R_circuit.pro or RLC_circuit.pro with Gmsh and click on the "Run" button in the left panel.

Features addressed in this tutorial

  • Coupling of finite elements and electric circuits
  • Definition of lumped circuit elements (voltage and current sources, resistors, inductors and capacitors)
  • Creation of netlists combining lumped elements and global finite element quantities (currents and voltages)

Additional information

Model R_circuit.pro shows how to implement a circuit with discrete elements in a static finite element simulation. Lumped resistors, voltage- and current-sources are used to connect four separate cubes with a certain conductivity, where an electrokinetic finite element formulation is solved.

Model RLC_circuit shows how to implement a circuit with discrete resistors, capacitors, inductors, voltage- and current-sources in a transient finite element simulation. The lumped elements are connected to three cubic-shaped resistors modelled with finite elements.
