Automotive customers — OEMs and tier-N suppliers across ICE, hybrid, and full-EV programmes — face shortening cycle times against tightening regulation. Electrification has rewritten the engineering profile of a vehicle: batteries dominate weight, e-machines dominate NVH, and thermal management couples into nearly every subsystem. DDSPLM — a Siemens Gold Partner and Smart Expert Partner — helps the engineering teams behind those vehicles ship faster without giving up on validation depth, with the Siemens Simcenter, NX and Altair simulation portfolio.
What’s changing under the hood
- Electrification is now mainstream, not a side project. Battery, e-machine and power-electronics design sit on the critical path of most new programmes.
- Software-defined vehicles raise the integration bar. Mechanical, electrical and controls domains have to share one model and one revision spine.
- Thermal is the new bottleneck. Fast charging, high-density packs and power electronics make coupled electro-thermal simulation unavoidable.
- India is localising the supply chain. PLI-backed investment means more domestic battery, motor and component engineering — and demand for the tooling depth global Tier-1s already run.
EV-specific stack
- Battery cell, module and pack design in NX CAD plus Simcenter STAR-CCM+ for electro-thermal coupling.
- E-machine design with Simcenter MotorSolve / MAGNET, then thermal and CFD validation.
- Powertrain integration via Simcenter Amesim 1D system simulation.
- Crash and structural durability with Altair Radioss and HyperWorks.
Across the rest of the vehicle
- NVH analysis with Simcenter 3D and Test.Lab.
- HVAC and cabin-comfort CFD.
- Body-in-white forming, joining, and weld-distortion simulation.
- Teamcenter-based PLM for variants, options, and supplier collaboration.
Where we add value
The hard part of a modern vehicle programme is rarely one solver — it’s stitching battery, e-machine, cooling-loop and structural models into a chain that produces a single defensible answer on range, performance and durability. That integration work is where our engineering team spends most of its time.
