FEA software (finite element analysis) is the backbone of structural, thermal and dynamics validation. DDSPLM supplies and supports the Siemens Simcenter and Altair FEA portfolio across India — and, as a Siemens Gold Partner and Smart Expert Partner, helps engineering teams pick, license and deploy the right finite-element tool for the job in automotive, aerospace, defense and industrial-machinery work.
Which FEA software for which job
- Simcenter Femap + Nastran — CAD-agnostic pre/post-processing with the industry-standard Nastran solver. The default for focused linear and modal structural analysis.
- Simcenter 3D — multi-discipline FEA on one model: structures, thermal, dynamics, acoustics, durability and composites without re-prepping for each physics.
- Altair OptiStruct (in HyperWorks) — structural FEA solver with best-in-class topology, topography and lattice optimisation.
- Altair HyperMesh — industrial FE pre-processing and meshing, solver-neutral across Nastran, OptiStruct, Abaqus and LS-DYNA.
- Altair SimSolid — meshless structural analysis directly on full CAD assemblies, for fast early-stage checks without meshing.
Mechanical simulation beyond FEA
Most teams pair FEA with adjacent physics — CFD for fluid and thermal flow, and 1D system simulation for sizing decisions upstream of detailed analysis. See the full CAE & simulation portfolio for how the tools fit together.
Why DDSPLM
We don’t just resell licences — we size the deployment, run the rollout, train your engineers, and support the renewal cycle. That full-stack model is what turns FEA software into validated results.
Industries we serve with FEA
- Automotive & EV — body-in-white crash, NVH, powertrain durability, battery pack structural integrity, EV motor housing thermal-structural coupling.
- Aerospace & defence — airframe static and fatigue, composite layup verification, landing gear impact, vibration qualification per DO-160 and MIL-STD-810.
- Industrial machinery — pressure vessel design to ASME, crane and hoist structural validation, rotating-equipment dynamics.
- Electronics — PCB-level thermo-mechanical stress, drop-test simulation, connector fatigue.
FEA services — when you need analysis, not just software
Not every team needs a permanent licence. DDSPLM’s CAE services team runs outsourced FEA projects on the same Siemens and Altair tools we sell — structural, thermal, vibration, fatigue and crash analysis, delivered as fixed-scope projects or bench-strength augmentation.
Common questions about FEA software
What is finite element analysis? FEA breaks a complex geometry into small elements (the “mesh”), applies loads and boundary conditions, and solves for stress, strain, temperature or vibration response. It predicts how a part or assembly will behave under real-world conditions — before a prototype is built.
Which FEA tool should I pick? It depends on the solver you need and the workflow you want. Simcenter Femap is best for standalone, solver-neutral FEA. Simcenter 3D is ideal when you need multi-physics on one model. Altair HyperMesh is the choice when meshing quality on large assemblies matters most.
Can I try FEA software before buying? Yes. DDSPLM offers evaluation licences for all Siemens Simcenter and Altair FEA products. Request a trial →
