Magnetodynamics - electromagnet and transformer
Browse model files — Download zip archive

Quick start

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

Features addressed in this tutorial

  • Eddy current problems in frequency- and time-domain
  • Complex-valued solutions (phasors)
  • Use of a template library containing generic formulations

Additional information

The electromagnet model electromagnet.pro is the same as in Tutorial 2, but set up using a predefined template formulation file. In addition to static fields, the template provides a frequency-domain magnetodynamic formulation to compute the induced currents in the magnetic (and conducting) core in steady-state, for a sinusoidal source current.

The transformer model transfo.pro uses the same template file to model a simple transformer, in both frequency- and time-domain. A circuit coupling is used to connect the primary winding to a voltage source and the secondary winding to a resistive load.
