EM Workbench/it

Introduzione

The EM (ElectroMagnetic) Workbench provides the CAD front-end interface to some open source free solvers. At present it supports the 3D magnetoquasistatic impedance solver FastHenry (i.e. inductance and resistance extraction at "low" frequencies). Support for the 3D electrostatic capacitance solver FasterCap is ongoing.

Installazione

I risolutori elettromagnetici FastHenry2 e FasterCap devono essere installati separatamente. I loro codici binari e i sorgenti sono liberamente disponibili in FastFieldSolvers.

Utilizzo

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.

Strumenti di FastHenry

Questi sono gli strumenti utilizzati per interfacciarsi con FastHenry:

• FHNode: Crea un oggetto FastHenry Node
• FHSegment: Crea un oggetto FastHenry Segment
• FHPath: Crea un oggetto FastHenry Path
• FHPlane: Crea un oggetto FastHenry uniform conductive Plane
