Introduction

The ElectroMagnetic (EM) Workbench provides the CAD front-end interface to some open source free solvers. At present it supports the magnetoquasistatic impedance solver FastHenry (i.e. inductance and resistance extraction at "low" frequencies). Support for the electrostatic capacitance solver FasterCap is ongoing.

The EM Workbench is a FreeCAD addon, that can be installed on demand. It is not part of the standard FreeCAD install.

Installation

At present, the EM Workbench must be manually installed. See the instructions in the README at the EM Workbench GihHub page.

The electromagnetic solvers FastHenry2 and FasterCap must be installed separately. Their binary codes as well as the sources are freely available from FastFieldSolvers.

FastHenry Tools

These are tools used to interface with FastHenry:

API

The EM tools can be used in macros and from the Python console by using the EM API.

Tutorials

Some video tutorials are available:
