## Quick start
|
|
|
|
|
|
To run the model, open `magnus.pro` with Gmsh
|
|
|
and click on the "Run" button in the left panel.
|
|
|
|
|
|
## Features addressed in this tutorial
|
|
|
|
|
|
* Multivalued scalar field
|
|
|
* Potential flow
|
|
|
* Non-linear iteration on an associated global quantity
|
|
|
* Use of a run-time variable in a Post-Operation (via Python)
|
|

|
## Additional information
|
|
|
|
|
|
This model solves a 2D potential flow around a cylinder or a naca airfoil,
|
|
|
placed in a uniform flow.
|
|
|
The lift force is evaluated by both the integration of pressure
|
|
|
and the Kutta-Jukowski approximation.
|
|
|
In the Airfoil case, a non linear iteration is done
|
|
|
by means of a pseudo-newton scheme,
|
|
|
to ensure that the Kutta condition is verified.
