SIMULATION Mahindra & Mahindra improves vehicle design and time to market with Dassault Systèmes SIMULIA applications

Nov 24, 2020

SIMULIA applications help in fuel efficiency improvement, light weighting, passenger comfort and EMI/EMC compliance. The PowerFLOW CFD suite using Lattice Boltzmann Method (LBM)-based flow solver help in increasing fuel efficiency through high fidelity aerodynamics simulations. SIMULIA applications are extensively used in powertrain and in body durability across the farm and tractor division, the electric vehicle division, and the passenger vehicle division.

Dassault Systèmes at the 3DEXPERIENCE Conference 2020 India on design, modelling and simulation, has announced that Mahindra & Mahindra is using SIMULIA applications at Mahindra Research Valley (MRV), Tamil Nadu, to meet safety regulations, emission norms, reduce costs, improve fuel efficiency and achieve a faster time to market of vehicles. These applications include PowerFLOW Computational Fluid Dynamics (CFD) solutions, Abaqus Unified FEA and CST Studio Suite. Mahindra & Mahindra uses these solutions to transform its vehicle design process and improve efficiency across the product development lifecycle for its portfolio of passenger vehicles, farm and tractor division and electric vehicles.

Dassault Systèmes’ SIMULIA applications enable engineers and R&D teams at MRV to enhance its engineering simulations and accurately predict real world conditions. It helps evaluate product performance and identifies potential flaws, early in the design process prior to building physical prototypes. The solutions virtually validate the vehicle performance, and optimise vehicle quality, durability, and experience. With the performance trade-off analysis, simulation applications are helping MRV engineering and R&D teams to produce automobiles that are sustainable and meet global standards.

Talking about MRV’s partnership, Sitarameswara Sarma Akella, Vice President - Automotive Sector, Mahindra & Mahindra, asserted, “Our long-term partner, Dassault Systemes’ digital simulation-based approach is valuable in this regard allowing for upfront simulation at the early-design stage when there is more flexibility for change. Further in the product development process, the realistic simulation solutions are used for virtual validation, giving us higher confidence before a regulatory test.” He added, “Our R&D centres in India and USA extensively used Dassault Systemes’ simulation technologies on the cloud enabling remote collaboration on important projects during the pandemic.”

Taking the talks further, Deepak NG, Managing Director, India, Dassault Systèmes, mentioned, “Our simulation portfolio helps our automotive customers align with regulatory norms like Bharat Stage Emission Standards (BSES) and Bharat New Vehicle Safety Assessment Program (BNVSAP) resulting in lower carbon footprint and a safer, more fuel-efficient product, all within ever-shrinking product development times.”

The SIMULIA PowerFLOW CFD suite accurately and efficiently performs aerodynamic, aeroacoustics and thermal management simulations. Using the Abaqus Unified FEA, automotive companies can consider full vehicle loads, dynamic vibration, multibody systems, nonlinear static and thermal coupling for virtual testing. The CST Studio Suite - a 3D EM analysis software designs, analyses, and optimises electromagnetic (EM) components and systems. It facilitates EM analysis like performance and placement of antennas, exposure to human body of EM field and EMI/EMC compliance that have become increasingly relevant.
