AxesSim – ElectroMagnetic Compatibility (EMC)

ElectroMagnetic Compatibility (EMC) is the ability of an electrical or electronic system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to any other equipment in that environment. Essentially, it is about controlling both emissions (noise generated by the device) and susceptibility/immunity (resistance to external noise).

Radiation/Emission (EMI) control relies on prediction and mitigation of unwanted fields emitted by devices. This includes modeling the radiation of cables (common/differential mode) and equipments, identifying leakage through shielding (seams, slots), …

Susceptibility (EMS) is the system’s ability to operate correctly in the presence of external disturbances. During their operational life, complex systems are subject to electromagnetic environments that may occur due to a variety of natural or man-made environmental sources such as electromagnetic impulses (EMP), radio frequency interference (RFI), high intensity radiated fields (HIRF), electromagnetic interference (EMI), lightning strikes, etc. Simulation allows evaluation of Radiated electromagnetic fields penetration inside systems and its coupling with cables and equipments.

AXS-EMC (ElectroMagnetic Compatibility) is the ideal simulation software to manage large-scale and highly complex issues described above.

AXS-EMC simulation software allows :

N

The evaluation of radiated EM fields by cable harnesses installed in complex systems (mandatory for EMC design of systems)

N

The assessment of radiated and conducted constraints at the equipment level (essential to define protection of the systems as well as to check their robustness during qualification / certification phase)

By making it possible to visualize current paths and invisible fields, AXS-EMC is essential for optimizing design, identifying hotspots, and ensuring compliance with EMC standards before expensive laboratory testing.

AXS-EMC (ElectroMagnetic Compatibility) relies on MaxSim tool.

It provides a set of powerful features for such issues :

N

A very efficient parallel FDTD solver for reliable resolution of major problems

N

A complete set of sub-cellular models (wires, cables, slots, joints, …) that allows to realistically take into account electrical and electromagnetic characteristics of the system, with limited constraints on the size of the mesh

N

Dispersive and anisotropic material models (imperfections in screening material, eg : skin effect or penetration of radiation through finite conductivity walls)

AXS-EMC (ElectroMagnetic Compatibility) also relies on CableSim.

It offers advanced features for analyzing complex cable bundles installed in their operating environment such as :

N

Handling of multi-level shielding

N

Non-linear protection circuits against transients

N

Resolution of cable harnesses with the Multi-Conductor Transmission Line method (MTLN)

N

Common mode return current in system installation managed by 3D solver (Bidirectional coupling method).

AXS-EMC (ElectroMagnetic Compatibility) embeds the post-processing tool KaWa :

N

A full set of plots allowing a quick and easy analysis.

- 1D curves: real and complex curves, polar views, histograms
- 2D: mappings and contours renderings
- 3D views: points, quivers, surfaces.

N

Multi-dimensional data post-processing capabilities (signal processing, statistical analysis, …)

Use cases solved by this solution

Performance of the TETA Discontinuous Galerkin solver on the Jean Zay supercomputer

To be fully exploited, the massively parallel architecture of super-computers requires the use of specific software design as well as parallelization technologies and dedicated programming languages.
AxesSim had the opportunity to test its Discontinuous Galerkin (DG) TETA solver on the new Jean Zay supercomputer from CNRS, and thus demonstrate its know-how in this field.
