Introduzione
The ElectroMagnetic (EM) 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.
Il workbench EM è un addon per FreeCAD, che può essere installato su richiesta. Non fa parte dell'installazione standard di FreeCAD.
Installazione
Al momento, EM Workbench deve essere installato manualmente. Vedere le istruzioni nel README alla pagina EM Workbench GihHub.
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.
FastHenry Tools
These are tools used to interface with FastHenry:
- FHNode: Creates a FastHenry Node object
- FHSegment: Creates a FastHenry Segment object
- FHPath: Creates a FastHenry Path object
- FHPlane: Creates a FastHenry uniform conductive Plane object
- FHPlaneHole: Creates a FastHenry uniform conductive plane Hole object
- FHPlaneAddRemoveNodeHole: Add or Remove a Node or a Hole from/to a conductive plane
- FHEquiv: Creates a FastHenry node Equivalence object
- FHPort: Creates a FastHenry Port object
- FHSolver: Creates a FastHenry Solver object
- FHInputFIle: Creates a FastHenry Input File
FasterCap Tools
At present, FasterCap is supported via some Macros in the Export_mesh.py file available in the ElectroMagnetic Workbench GitHub source code.
API
The EM tools can be used in macros and from the Python console by using the EM API.
