Electromagnetic Environmental Effects
AXS-E3 is ideal for evaluating interactions between complex structures of large dimentions (composite materials, installed wiring harnesses, etc.) and electromagnetic environments.
AxesSim – Electromagnetic Environmental Effects
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. Sources in question are mainly electromagnetic impulses (EMP), radio frequency interference (RFI), high intensity radiated fields (HIRF), electromagnetic interference (EMI), lightning strikes, etc.
Radiated electromagnetic fields penetrate inside systems (different mechanisms operate according to the frequency band: by the openings or by diffusion through the walls) and couple with the cabling and the electronic equipment, inducing electrical parasites which can lead to transient or permanent disturbances of the equipment. Functional impacts of these disturbances can have major or even catastrophic consequences on the systems.
Thus E3 applications often involve large electrical structures (planes, ships, land vehicles) containing critical details (joints, cables).
AXS-E3 (Electromagnetic Environmental Effects) is the ideal tool to manage large-scale and highly complex issues described above, AXS-E3 permit the assessment of radiated constraints conducted at the equipment level which is essential to define protection of the systems as well as to check their robustness during qualification / certification phase as a complement to measurements.
AXS-E3 (Electromagnetic Environmental Effects) provides a set of powerful features for such obstacles:
A very efficient parallel FDTD solver for reliable resolution of major problems;
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;
Dispersive and anisotropic material models (imperfections in screening material, eg : skin effect or penetration of radiation through finite conductivity walls);
AXS-E3 (Electromagnetic Environmental Effects) includes advanced features for analyzing complex cable bundles installed in their operating environment.
Resolution with the Multi-Conductor Transmission Line Theory (MTL), available method for cables with arbitrary path of the return current feedback paths
Handling of multi-level shielding
Non-linear protection circuits against transients
AXS-E3 is based on the distributed and collaborative simulation environment CuToo. As a consequence, it is easy to build a repository of templates (reusable materials, protection elements, …) and to share them with other users:
- reusable and independent mesh models of the system,
- capitalization and research capacity.
