## 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
|
|
|
|
|
|
* Use of a generic template formulation library
|
|
|
* Frequency- and time-domain dynamic solutions
|
|
|
|
|
|
## Additional information
|
|
|
|
|
|
The electromagnet model `electromagnet.pro` is the same as in [Tutorial
|
|
|
2](Magnetostatics), 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.
