FEKO  FEKO is a computational electromagnetics software product developed by Altair Engineering. The name is derived from the German acronym "FEldberechnung für Körper mit beliebiger Oberfläche", which can be translated as "field calculations involving bodies of arbitrary shape". It is a general purpose 3D electromagnetic (EM) simulator. FEKO originated in 1991 from research activities of Dr Ulrich Jakobus at the University of Stuttgart, Germany. Cooperation between Dr Jakobus and EM Software & Systems (EMSS) resulted in the commercialisation of FEKO in 1997. In June 2014, Altair Engineering acquired 100% of EMSS-S.A. and its international distributor offices in the United States, Germany and China, leading to the addition of FEKO to the Altair Hyperworks suite of engineering simulation software. The software is based on the Method of Moments (MoM) integral formulation of Maxwell's equations    and pioneered the commercial implementation of various hybrid methods such as:       A Finite Difference Time Domain (FDTD) solver was added in May 2014 with the release of FEKO Suite 7.0.
