About us

Who we are

Our history

FastFieldSolvers is born in the early year 2000, from past experience using FastHenry and FastCap field solvers. Since that year, FastFieldSolvers has freely provided to the field solvers user community the Windows version of FastCap and FastHenry, originally developed for Unix operating systems only, with bug fixes and enhancements; and all the related support activity.

FastFieldSolvers eventually structured as a company and released FasterCap, FastModel, the ElectoMagnetic workbench, in-house software developments freely available in Open Source with permissive licenses, and started offering consultancy services.

Over the years, with the wide experience acquired supporting the large Fast Field Solvers user base, FastFieldSolvers has become a de-facto, authorative reference point for FastCap and FastHenry, as well as for all related topics about capacitance and inductance extraction. The business model changed in line with the original open source philosophy, focusing not on software product sales, but on services and solutions.

Our vision

Our vision is to be the 'SPICE' of the ElectroMagnetic world, that is to be what SPICE has been for the circuit simulation world.

Our mission

Our mission is to provide you comprehensive solutions, with great attention to your requests.
