## Quick start
|
|
|
|
|
|
|
|
To run the model, open `floating.pro` with Gmsh
|
|
|
|
and click on the "Run" button in the left panel.
|
|
|

## Features addressed in this tutorial
|
|
|
|
|
|
|
|
* Global quantities and their special shape functions
|
|
|
|
* Duality
|
|
|
|
* More on ONELAB parameters (flags, model options, check boxes, menus, ...)
|
|
|
|
|
|
|
|
## Additional information
|
|
|
|
|
|
|
|
This is a further step on the electrostatic 2D model of a microstrip.
|
|
|
|
We show in this tutorial how GetDP takes advantage of global quantities and the associated global basis functions
|
|
|
|
* to reduce the number of unknowns
|
|
|
|
* to deal with floating potentials
|
|
|
|
* to compute efficiently the electrode charges,
|
|
|
|
which are precisely the energy duals of the electrode voltages
|
|
|
|
* to provide output quantities (charges, armature voltages, capacitances, ...)
|
|
|
|
that can be immediately used in a external circuit.
