EM Workbench/de

Einleitung
Der Arbeitsbereich EM (ElectroMagnetic) stellt das CAD front-end interface für einige open source free solvers zur Verfügung. Aktuell unterstützt es den 3D magnetoquasistatic impedance solver FastHenry (d.h. Induktivitäts- und Widerstandsermittlung für "niedrige" Frequenzen). Unterstützung für den 3D electrostatic capacitance solver FasterCap ist in Arbeit.



Installation
Der Arbeitsbereich EM ist ein externer Arbeitsbereich, der mit FreeCADs Addon-Manager installiert werden kann. Dies kann über den Menüeintrag erfolgen.

Die Löser für elektromagnetische Zusammenhänge FastHenry2 und FasterCap müssen separat installiert werden. Ihre Binärcodes und auch die Quelldateien sind frei erhältlich von FastFieldSolvers.

FastHenry
FastHenry is a software for computing the frequency-dependant self and mutual inductances and resistances of a generic tridimensional conductive structure, in the magnetoquasistatic approximation. It can also generate Spice-compatible, multiple-frequency equivalent-circuit models.

Knowledge of FastHenry is a pre-condition for the proficient usage of the ElectroMagnetic Workbench for FastHenry. We suggest you to read the original FastHenry User's manual and play a bit with the sample files that are provided with the installation.

FasterCap
FasterCap is a powerful three- and two-dimensional capacitance extraction program.

Knowledge of FasterCap is a pre-condition for the proficient usage of the ElectroMagnetic Workbench for FasterCap. We suggest you to read the original FasterCap help file and play a bit with the sample files that are provided with the installation.
