## 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.
