Numerical Methods

FEKO offers a wide spectrum of numerical methods and hybridisations, each suitable for a specific range of applications.
Numerical Methods

Hybridisation expands the range of applications, allowing the solution of problems which would be intractable with any individual method. All together, these methods allow the user to solve a diverse set of problems. Below, the EM simulation map is shown. It is a graphic illustration of the relative ranges of applicability of the various methods.
