*Extraction*

## Description

Calculates the capacitance of/between conductors. For the calculation any conductor will we spited into panels with a constant charge. The 3d setup in the LayerManager is used for the z-coordinates. The charge calculation for a small amount of panels can be done inside the LayoutEditor. For bigger calculations the discretization data is store and the external calculation tool FastCap is called. FastCap is included in the LayoutEditor package.

**Usage:**

- select the shape part of a single conductor (or ground)
press to add as conductor (or for ground)

- repeat these steps for any conductor
- set material data
- start the calculation

## Algorithm

The FastCap algorithm is used for the calculations. It is a three dimensional calculation.
