A full frontal barrier crash test at an accredited Indian facility costs somewhere in the range of 8 to 15 lakhs per test, depending on the vehicle category and the instrumentation required. Add the cost of the physical prototype, which for a body structure evaluation at early design stage can be 40 to 80 lakhs, and you begin to understand why automotive Tier-1 suppliers in India have been looking hard at simulation as a way to reduce the number of physical tests they need to run.
This is not new thinking globally. European and American OEMs have been running structural simulation as a primary engineering tool rather than a supplementary check for over 15 years. In India, the adoption has been slower, partly because BNVSAP and Bharat NCAP regulatory requirements were relatively recent drivers, and partly because simulation software and engineering expertise were historically concentrated in OEM technical centres rather than in the Tier-1 supplier base.
That is changing now. Indian Tier-1 structural and body engineering suppliers are actively building in-house CAE capability, and Simcenter is one of the primary platforms they are investing in.
Simcenter Nastran and Simcenter 3D cover the structural analysis and durability domains that Indian Tier-1s use most. For body structure work, the ability to run nonlinear explicit solvers for impact and crash events, within the same environment where you do your static stiffness and modal analysis, reduces the workflow fragmentation that comes from using separate tools for different analysis types.
The integration with Siemens NX for geometry input means that when the design team updates a cross section or changes a gauge, the change propagates to the simulation mesh without requiring the CAE engineer to spend half a day rebuilding the model. For Indian programs where design iteration cycles are compressed and engineering teams are smaller than at global OEMs, this kind of connected workflow is a real productivity multiplier.
For NVH work specifically, which is becoming a competitive differentiator in Indian vehicles as customer expectations for cabin quality rise, Simcenter’s testing and simulation correlation capability lets teams align their virtual models with physical test results more systematically. This matters because a simulation model that has been correlated against physical test data can be trusted for subsequent design iterations in a way that an uncorrelated model cannot.
A typical Indian Tier-1 structural supplier building crash management systems or door structures for multiple OEM platforms might have previously run two to three physical bucks per program to validate energy absorption behavior. With a validated simulation model, that same program might run eight to twelve virtual design iterations to optimize section geometry, material gauge, and joining configurations, then run a single physical validation test against the final design. The cost and time savings are substantial and the final design quality is generally better because more design alternatives were explored.
The transition requires upfront investment in the software and, more importantly, in building the in-house CAE engineering capability to run the simulations correctly. Simulation results are only trustworthy when the person setting up the model understands the physics involved and the limitations of the analysis methodology. Building that competency, either through hiring experienced CAE engineers or through structured training, is the critical success factor that separates Tier-1s who get real value from simulation from those who run models but cannot fully trust the results.
India’s Bharat NCAP program, which began rating passenger vehicles in 2023, has accelerated safety engineering investment across the industry. OEMs are putting pressure on their Tier-1 structural suppliers to front-load safety performance validation earlier in the program development cycle. That pressure cannot be absorbed through additional physical testing alone. Simulation capability in the Tier-1 supplier base is becoming a qualification criterion, not just a nice-to-have.
If you are a body or structural Tier-1 in India and you are still doing structural validation primarily through physical testing, the window for building simulation capability before it becomes a customer requirement is narrowing.
