Multiphysics Simulation for Automotive
Engineering Confidence Into Every Design Decision
Modern EVs and autonomous systems demand tight control over battery safety, motor efficiency, power electronics reliability, and sensor performance. These interconnected challenges leave no room for guesswork. Ansys delivers the multiphysics accuracy engineers need to solve issues early—optimizing thermal behavior, electromagnetic integrity, and vehicle efficiency using tools like Motor‑CAD, HFSS, and Fluent. The result: fewer prototypes, reduced risk, and faster delivery of safer, smarter vehicles.
The Roadmap to Next-Gen Mobility
- Battery Safety & Failure Risk
Preventing thermal runaway starts with early insight. Ansys Fluent supports battery thermal management and safety analysis so teams can evaluate risk sooner and reduce reliance on expensive physical testing. - Thermal Management & EV Range
EV performance is won or lost through efficiency and heat. Ansys Fluent enables advanced CFD and thermal simulation to optimize cooling strategies across batteries, inverters, and e-drives. - E-Drive Efficiency & Integration
Demanding duty cycles require integrated motor analysis. Ansys Motor-CAD accelerates traction motor and e-drive development with integrated electromagnetic, thermal, and mechanical analysis for faster design exploration and fewer prototype loops.
- EMI/EMC & Sensor Robustness
High‑voltage switching can disrupt critical signals. Ansys HFSS models electromagnetic behavior and EMI/EMC risks in 3D to help teams prevent issues early and protect ADAS sensor reliability and connectivity performance. - Functional Safety & Cybersecurity Readiness
Software-defined vehicles raise new expectations for safety-aligned development and secure updates. Ansys supports validation workflows that help teams align with ISO 26262 / AUTOSAR requirements while strengthening robustness across embedded software and electronics integration.
Engineering Simulation: The Future of Automotive Innovation
As the automotive industry experiences disruption in areas of technology, competition, regulation and shifting consumer demand, engineering simulation leads the way in delivering the highest level of competitive advantage and proven return on investment.
Design high-efficiency traction motors and integrated e-drives.
Ansys Motor-CAD
Electric powertrains demand rapid iteration across electromagnetic performance, thermal limits, and mechanical constraints. Ansys Motor-CAD enables fast, accurate electric machine design exploration—helping engineering teams optimize torque, efficiency, and temperature rise while reducing reliance on prototype-heavy development cycles.
