EMA与Ansys共同推出的新型工作流程Ansys EMA3D Cable，是一套用于解决EMC设计问题的平台级EMC电缆建模稳健型解决方案。若在设计阶段的早期使用EMA3D Cable，便能帮助工程师提高产品性能预测的保真度，降低开发成本，减少对物理原型的需求，并可将测试结果作为最终验收和认证的依据。
EMA总裁Timothy McDonald博士表示：“EMA3D Cable将帮助工程师有效地评估复杂线束系统设计，为各类交通工具评估保护方案。通过与Ansys合作开发这一强大的新型工作流程，我们双方的用户将显著增强自身的线束兼容性设计，在EMC认证过程中可大幅降低成本和风险。”
Ansys物理业务部高级副总裁Shane Emswiler表示：“OEM厂商设计的新型交通工具越来越轻巧。这类设计中无法使用传统线束屏蔽配置，往往会形成EMI漏洞。使用EMA3D Cable设计线束将有助于工程师改善安全关键型EMI问题，如高强辐射场（HIRF）、雷击、串扰和电磁脉冲等，提高认证支持水平并节省设计费用。”
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.
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

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
