Altair Feko: Supported solution method and technique combinations

Esti Hansmann

This article lists the supported solution method and technique combinations in Feko.

When selecting a solution method or technique in Feko, it is important to know which method and technique combinations may be used in a model, else CADFEKO and the Feko Solver will give an error.
