Advanced EMC Solutions is proud to announce the release of a 'combined' radiation calculation solution for cable harness systems.

The solution is as a result of the cooperation between SimLab Software GmbH of Munich, Germany and EM Software and Systems of Stellenbosch, South Africa.

The solution, now offered throughout North, South and Central America by Advanced EMC solutions, can lead to shortened calculation times and less user intervention when compared to simulations involving 'closed' full wave analysis.

3D full wave analysis software products, like FEKO, are suitable tools when dealing with radiation and irradiation effects in large systems such as automobiles or airplanes.

However, the complexity increases rapidly with respect to size, resulting from long calculation times and large memory requirements.

For most applications, a combination of tools is the only possibility for achieving results in reasonable times.

With radiation calculations inside a car chassis, for example, the user can exchange radiation simulation data results from CableMod to FEKO.

The data exchange is done by means of a so-called radiation simulation data (rsd) - file that is generated by CableMod.

FEKO (an extremely sophisticated EMC simulation tool for radiation and irradiation) was developed by EM Software and Systems of South Africa..

The company originated out of the University of Stuttgart and has been successful in introducing FEKO to a wide range of customer worldwide.

In particular, FEKO - is used extensively in the European automotive industry.

SimLab Software has partnered with EMSS to develop an interface to enable the transfer of data between relevant tools.

At this time, the interface is targeted towards CableMod only.

SimLab has developed the following RSD Export and ISD Import interfaces: RSD Export - Allows files created in CableMod and PCB Mod and needed to determine the radiated E and H field in either RadiaSim or FEKO to be transferred between those tools.

It is for this reason that the RSD Export capability is included in RadiaSim * ISD Import - Allows files created in CableMod and needed to determine the irradiation in FEKO to be transferred to FEKO and back to CableMod.

EMSS was instrumental in the development of the FekSiml interface.

This permits data transfer from CableMod (through RSD Export or ISD Import) in order to include the transmission lines in FEKO as sources for the analysis of complex structures and the computation of derived quantities such as induced surface currents/charges, near- and far-fields.

In order to transfer the files enabling FEKO to calculate radiation or irradiation one requires the following : RSD Export and ISD Import and FekSiml.

These 3 together are available as a package called CabFek from Advanced EMC Solutions.
