## Description

This project is dedicated to building an ElectroMagnetic workbench for [FreeCAD](https://www.freecadweb.org). FreeCAD is a free 3D parametric CAD.
FreeCAD is used as pre-processor interfacing to the open source electromagnetic field solvers [FastHenry](https://www.fastfieldsolvers.com/fasthenry2.htm) and [FasterCap](https://www.fastfieldsolvers.com/fastercap.htm).

At present, the workbench supports:

- [FastHenry](https://www.fastfieldsolvers.com/fasthenry2.htm) inductance solver: ongoing development including GUI support
- [FasterCap](https://www.fastfieldsolvers.com/fastercap.htm) capacitance solver: ongoing development, today at the stage of Python macro only, for creating an input file


## Installing

The ElectroMagnetic workbench is managed as a FreeCAD addon. This addon can be downloaded by clicking the **Download ZIP** button found on top of the page, or using **Git**. The addon must be placed in your user's FreeCAD/Mod folder. 

**Note**: Your user's FreeCAD folder location is obtained by typing in FreeCAD's python console: `FreeCAD.ConfigGet("UserAppData")`.

You must then rename the new folder 'EM'. I.e., the new folder structure must be <UserAppData>/Mod/EM. Opening, or closing/reopening FreeCAD then reloads the workbenches, and the E.M. workbench will show up in the pull-down workbenches menu in FreeCAD.
