EM Software & Systems (EMSS) and ESI Group announced that they have joined forces in order to provide a solution for the analysis of complex cable bundles in their operating environment.

The introduction of more electronic systems on vehicles (e.g. automobiles, trains and aircraft) is putting increasing demands on the integration of such systems from an interference (electromagnetic compatibility, EMC) point of view. One such aspect is the coupling of signals from one system into the cables, or cable bundles, connected to an adjacent system. For example, signals or unwanted electromagnetic noise emitted from the engine area of an automobile can interfere with the communication, navigation or entertainment systems. An even worse case would be interference with critical systems such as safety airbags, breaking systems etc. Although measurements are normally used during the design process, simulations can offer an insight into the interference mechanisms, with significant time and cost savings.

The analysis of complex cable bundles, their connections, and their surrounding environment (e.g. the chassis of an automobile), is one of the most challenging aspects of electromagnetic field analysis. No single full 3D EM solver is currently capable of a complete integrated solution and a combination, or hybrid, of solver techniques is required. With this cooperation and specifically through the interface between their respective solvers CRIPTE and FEKO, ESI Group and EMSS will provide their customers with a better solution to such challenging problems of electronic system compatibility.

CRIPTE uses 2D analysis at various positions along the cable bundles to calculate the multiconductor transmission line characteristics while FEKO, a full 3D EM solver, is used to analyse the structures surrounding the cable bundles.

The cooperation will extend beyond a simple interface between these two technologies, as both companies will also be using their respective sales and support networks to promote their respective products.
