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.
