A design may look correct in CAD. The real engineering question begins when that design is subjected to actual operating conditions.
- Will it carry the required load?
- Where will stress concentrate?
- Will repeated loading affect its life?
- Can vibration compromise performance?
- Is the design unnecessarily heavy?
- Will a mechanism behave as expected during operation?
These are problems CAE simulation answers before they become expensive physical problems. At DDSPLM, we provide engineering-led CAE simulation services covering structural FEA, fatigue and durability, contact analysis, modal and vibration studies, stiffness evaluation, motion and dynamic simulation, and design optimization.
What we support
Our CAE services support engineering teams at different stages of product development:
- New product and component validation
- Structural strength and integrity assessment
- Stress and deformation analysis
- Fatigue and durability evaluation
- Contact and clamping analysis
- Modal and vibration studies
- Stiffness evaluation (radial, axial, torsional)
- Design strength and weight optimization
- Tooling and die analysis
- Motion and dynamic simulation
- Drop, impact and crash with explicit solvers
- Thermal-mechanical coupling
- Failure investigation and design improvement
The simulation methodology is selected according to the engineering requirement rather than applying the same analysis to every product.
Real engineering challenges, real CAE applications
The strongest demonstration of simulation capability is not a list of software features — it is what the analysis helps an engineering team understand.
EOT crane — structural analysis. Structural FEA under defined operational loading to evaluate stress distribution, deformation and critical regions. The simulation gave the design team calculated structural behaviour to review against, rather than relying only on assumptions or physical testing.
Tractor seat — fatigue analysis. A seat assembly that performs adequately under a single static load may still fail under repeated operating cycles. Stress, deformation and fatigue analysis identified fatigue-sensitive regions and provided a basis for improving the design before production and physical validation.
Two-wheeler mirror — modal and vibration analysis. The mirror assembly is continuously exposed to vehicle vibration. Modal and structural analysis evaluated natural frequencies, mode shapes and displacement, highlighting critical vibration characteristics that informed decisions on rigidity and structural improvement.
Pipe clamping — contact analysis. In a clamping arrangement, the applied load alone does not explain assembly behaviour. Contact and clamping analysis evaluated how forces transferred between clamp and pipe, and where local stress and deformation developed.
Brake shoe body — strength and weight optimization. The brake shoe needed to meet structural requirements while reducing weight. Design strength integrity and weight optimization analysis identified opportunities for material and geometry changes without compromising structural performance — evaluated virtually before committing to physical tooling.
Draw die — fatigue and tool durability. A draw die experiences repeated operating loads during manufacturing. Stress, strain and fatigue life analysis identified regions where cyclic loading could influence durability, supporting tooling improvements and decisions aimed at extending tool life.
Stabilizer bar bush — stiffness evaluation. The bush must provide required stiffness in multiple directions. Radial, axial and torsional stiffness evaluation under different loading rates provided a clearer understanding of directional stiffness characteristics and functional performance.
Pantograph — rigidity, vibration and endurance. Evaluation of rigidity, vibration behaviour, natural frequency, mechanical endurance and operating behaviour under dynamic conditions supported design evaluation of a system required to maintain performance while operating.
Beyond conventional FEA: motion and dynamic simulation
Not every CAE problem is static. Mechanisms and moving systems require simulation of actual movement and interaction.
- Wheel loader — stress and deformation during boom loading and unloading, including interaction and collision between bodies.
- Valve-train assembly — motion simulation of the cam, rocker, tappet, valve and return spring under different operating conditions.
- Vehicle load data prediction — virtual road profiles and driving manoeuvres applied to CAE models to study vehicle behaviour under defined conditions.
These applications help engineers understand not only whether a structure can withstand a load, but how the system behaves while it is moving.

How we approach a CAE project
01 — Understand the problem. We review the product, operating environment, loads, constraints and objective.
02 — Define the analysis. The appropriate analysis method, material properties, contacts, loading and boundary conditions are established.
03 — Build and simulate. The CAE model is prepared — meshing, solver setup — and the required analysis is performed.
04 — Evaluate. Results are reviewed against the relevant engineering requirements.
05 — Improve. Where required, design alternatives are investigated for strength, durability, stiffness, weight or performance.
06 — Report. Simulation results are presented together with engineering observations that support the next design decision. The objective is not to deliver simulation plots — it is to convert results into useful engineering insight.
Tooling
We run Simcenter 3D, Altair HyperWorks, and supporting tools (Femap, NX Nastran, OptiStruct, Radioss). The right tool depends on the problem; we don’t fit every job to one solver.
Why DDSPLM for CAE simulation
- Engineering-led, not template-driven — the simulation approach is selected according to the engineering problem. Project experience ranges from EOT cranes and automotive components to tooling, brake assemblies, clutch assemblies, bushes and pantographs.
- Same tools you’d use in-house — Siemens Simcenter 3D, Femap, Nastran, Altair HyperWorks, OptiStruct and Radioss. Not a different toolchain from what your team would deploy.
- Siemens Smart Expert Partner — partner-grade certification on the simulation portfolio, not just CAD or PLM.
- India delivery, global standards — teams in Gurugram, Hyderabad, Bengaluru and Pune, working to documentation and quality standards set by automotive OEMs and aerospace primes.
Engagement models
| Model | When it fits |
|---|---|
| Fixed-scope project | Defined deliverable, defined deadline. |
| Bench-strength augmentation | Your team owns the project; we add hands. |
| Solver-time-as-a-service | You have engineers but not the licences or hardware. |
