ANSYS EMA3D Cable 2021 R1

Electro Magnetic Applications, Inc. (EMA) and Ansys is pleased to announce the availability of EMA3D 2021 R1 is a robust, platform-level electromagnetic compatibility (EMC) cable modeling solution for overcoming EMC design issues in aircraft, automobiles, electronics systems and industrial platforms.

EMA3D is a 3D Finite-Difference Time-Domain (FDTD) solver with an integrated multi-conductor transmission line solver. The two electromagnetic solvers co-simulate to allow for a complex cable harness to be accurately modeled inside complex geometry, such as an electronic device, a piece of machinery, an automobile or an aircraft. EMA3D has been validated on several high-profile aerospace platforms and the results were published at major conferences.

EMA3D has an advanced CAD preprocessor and GUI engine. The user never has to leave the environment for CAD development, property assignment or post processing. Meshing in EMA3D is fast and never fails, even with imperfections in the CAD geometry. EMA3D allows the user to quickly define the contents of the cable with a few clicks of the mouse. The simulation workflows are easy to learn and intuitive to the user. These combined features greatly reduce the analyst time to develop and simulate EMA3D models.

EMA3D is well-suited for simulations addressing electromagnetic compatibility (EMC), High Intensity Radiated Fields (HIRF), and lightning requirements early in the program before physical prototypes are complete. Users can specify realistic system signals as a source on cables or shields. The source may also be at the platform or environment level

The most anticipated EMA3D 2021 R1 Cable Updates  

HFSS Field Link: Ability to Use HFSS Near Fields as Source.
- Huygens source in EMA3D generates high fidelity representation of fields computed by HFSS.
- Full system simulation using HFSS and EMA3D Cable

Import of Harness Description List (KBL) Files.
- The import routine in EMA3D Cable reads the data available in the KBL files, automatically creates the harness path, and associates the correct cross-section.
- KBL can be exported by cable harness design tools, such as Zuken E3. series.
- EMA3D 2021 R1 has a workflow that supports cable geometry from CAD or exported within the KBL file.

Export S-Parameter Models.
- EMA3D Cable now extracts the S-parameter matrix of the entire model and generates a Touchstone file that can be used in any system/circuit simulator.
- EMA3D provides an option for fast extraction considering only the transmission line solver.
- Signal integrity and cross-talk effects may be analyzed easily in users’ familiar circuit simulation tools
