EM Workbench/pl

Wprowadzenie
Środowisko pracy EM (ElectroMagnetic) zapewnia interfejs CAD do niektórych darmowych solwerów open source. Obecnie obsługuje on solwer impedancji magnetoquasistatic 3D FastHenry (tj. ekstrakcję indukcyjności i rezystancji przy "niskich" częstotliwościach). Trwają prace nad obsługą solwera pojemności elektrostatycznej 3D FasterCap.



Instalacja
Środowisko pracy EM jest zewnętrznym środowiskiem pracy, które można zainstalować z poziomu Menadżera dodatków FreeCAD. Można to zrobić przez menu.

Solwery elektromagnetyczne FastHenry2 i FasterCap muszą być zainstalowane oddzielnie. Ich kody binarne oraz źródła są dostępne bezpłatnie na stronie 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.

FastHenry Tools
These are tools used to interface with FastHenry:
