Cable modeling software for simulating EMI/EMC effects on large platforms to provide design and EMC certification support.
Ansys EMA3D Cable specializes in analyzing lightning-induced electromagnetic (EM) effects on large platforms as well as cable EMI/EMC problems in aircraft and automobile platforms to support EMC certification. EMA3D Cable bolsters the design-to-validation workflow with system-design evaluation for cable harness models in the aerospace, automotive, military, oil and gas, consumer electronics and energy sectors.
Ansys EMA3D Cable simulates issues including EMI/EMC for cables, crosstalk, shielding effectiveness, lightning strikes, High Intensity Radiated Fields (HIRF) and Electromagnetic Pulse (EMP). These solutions will provide great cost benefits for companies in their design, validation and certification programs.
Test Electromagnetic Compatibility (EMC) of Complex Aircraft and Automobiles Systems with a Full Electromagnetic (EM) Model.
A manufacturer of civilian and military aircraft used Ansys EMA3D Cable to improve their understanding of aircraft system lightning response and validate a numerical approach to compliance that compared full aircraft simulations to full physical lightning transient analysis (LTA) tests.

Integrations with multiple Ansys tools (Discovery, Fluent, STK, and many more) support a wide range of computational Multiphysics applications and enhanced support for EMC design work and a new Cable Harness tool among the plethora of new capabilities in the EMA3D Cable.
New API and interoperability features with Ansys optiSLang, Ansys ModelCenter, Ansys STK, or a user Python script (pyEMA3D.) This feature allows 3D geometry and cables to be programmatically adjusted and the simulation re-run many times without user interaction.
New automated workflows enable full-device and full-vehicle simulation with automatic material assignment from Ansys Granta, automatic meshing, and automatic post-processing with standard electromagnetic compatibility (EMC) limit curves.
A new Multiple Cable Harness Tool permits the automatic import of additional cable database formats, the joining of different harnesses at connectors, and the rapid assignment of cable termination circuit elements.
EMA3D CABLE CAPABILITIES
When you’re designing the wiring harness for the controls system of a helicopter or the power distribution system of a next generation electric vehicle (EV), unwanted electromagnetic system effects can drastically uphold long-term production and cost-effectiveness.
As systems increase in complexity, system-level simulation becomes increasingly crucial to properly design an EMC solution and mitigate design failure in the future. EMA3D boasts many capabilities that can help validate your design of a single cable assembly, the high-level system, and every system in between.
Unwanted internal and external coupling can prevent or inhibit testing certifications. EMA3D Cable’s capabilities start with:
Radiated emissions simulations can be performed in full platforms, allowing the users to compute electric and magnetic fields anywhere in space due to radiation from cables and components. The automated coupling to HFSS allows engineers to consider the radiation of high-fidelity components such as packages, PCBs and antennas.
The coupling from ideal sources or specific components to cables installed in realistic platforms can be easily computed in the simulation environment. Radiated immunity tests, such as High Intensity Radiated Fields (HIRF) or Electromagnetic Pulse (EMP), can be easily simulated in Ansys EMA3D Cable.
Easily setup Bulk Current Injection (BCI) and conduct susceptibility tests on wiring harness bundles.
By using a very forgiving mesh, EMA3D Cable can handle extremely complex platforms to compute shielding effectiveness.
Compute induced voltage and currents on real wiring harness bundles using the transmission line solver.
Evaluate how the digital and analog signals are affected by the cable definition and external electromagnetic noise.
