The Examples have been selected to illustrate the features without being unnec-essarily complex or requiring excessive run times. The input files for the Examples can be foundin theexamples/ExampleGuide_modelsdirectory under the FEKO installation.

10 No results areprovided for these Examples and in most cases, the*.pre,*.cfmand/or*.optfiles have to begenerated by opening and re-saving the provided project files (*.cfx) before the computationof the results can be initiated by running the FEKO preprocessor, solver or can be used in one of three ways. The first and recommended way is to construct the entiremodel in the CADFEKO user interface. The second way is to use CADFEKO for the model geom-etry creation and the solution setup and to use scripting for advanced options and adjustment ofthe model (for example the selection of advanced preconditioner options). The last way is to usethe scripting for the entire model geometry and solution this document the focus is on the recommended approaches (primarily using the CADFEKO user interface with no scripting).
