FEKO also offers tools that are tailored to solve more challenging EM interactions, including dedicated solvers for characteristic mode analysis (CMA) and bi-directional cables coupling. Special formulations are also included for efficient simulation of integrated windscreen antennas and antenna arrays.
Combined with the MLFMM, and the true hybridization of the solvers, FEKO is considered the global market leader for antenna placement analysis.

Introduction to CADFEKO
CADFEKO is the FEKO component that facilitates the creation of CAD geometry using canonical structures and perform boolean operations. It also supports the import and modification of CAD models and meshed geometries. The setting of material properties, solution parameters and the required calculations defined by the user, are all part of the CADFEKO model. If an optimisation search is required, the optimisation parameters and the goal functions can be specified.

Introduction to POSTFEKO
POSTFEKO is used mainly for two purposes: to validate meshed geometry and to analyse results. Validation of mesh geometry is done so that users can confirm that their models are correct before starting a simulation. This is particularly useful when models are created using EDITFEKO, but is just as relevant for CADFEKO modelling. Analysis of results is the other primary function of POSTFEKO. Once a model has been simulated, POSTFEKO can be used to display and review the results. A variety of tools are available to help visualise data in a constructive manner.
Multiple models, with their geometry (in *.fek files) and results (in *.bof files), can be displayed in a single POSTFEKO project session. The displays are automatically updated each time the model and/or results are updated.
