Many of the most important engineering decisions affecting weight, stiffness, geometry, motion and manufacturability are made during the early stages of product development. When simulation is introduced only after a design is nearly complete, engineering teams may discover problems too late and be forced to redesign geometry, materials or structural concepts.
Simcenter Inspire is a CAE solution designed to bring simulation and optimization closer to the design process. It combines geometry modeling, engineering simulation, design optimization and manufacturing-oriented capabilities within a unified environment.
Instead of using CAE only as a final verification step, engineering teams can use Simcenter Inspire to explore alternatives, evaluate performance and improve product concepts while the design is still evolving.

What is Simcenter Inspire?
Simcenter Inspire is a simulation-driven design platform that enables engineers to create geometry, evaluate performance, optimize structures and explore design alternatives earlier in the product-development process.
A key advantage is its ability to make engineering simulation more accessible to design engineers. Teams do not necessarily need to complete the full CAD model before obtaining useful performance feedback.
A conventional workflow may look like:
Concept → Design → Finalize CAD → Simulation → Discover Issues → Redesign
A simulation-driven workflow can instead become:
Concept → Simulate → Optimize → Refine Design → Validate → Manufacture
This approach is commonly described as simulation-driven design: using simulation as a decision-making tool during design rather than only as a final verification activity.
What happened to Altair Inspire?
Following the integration of Altair technologies into Siemens’ simulation portfolio, Altair Inspire is now named Simcenter Inspire.
Altair Inspire → Simcenter Inspire
Users may still search for legacy terms such as “Altair Inspire” or “Inspire topology optimization.” However, the current product name should be presented as Simcenter Inspire.
What engineering challenges does Simcenter Inspire address?
Mechanical product design rarely involves optimizing a single requirement. Engineers often need to balance several objectives at the same time:
- Reduce product mass
- Maintain or improve structural stiffness
- Control stress and deformation
- Evaluate mechanism motion
- Improve manufacturability
- Use material more efficiently
- Reduce design iterations
- Evaluate more product concepts
Simcenter Inspire helps bring these considerations into the design process earlier so engineering teams can make more informed decisions before the geometry becomes difficult or expensive to change.
Key capabilities of Simcenter Inspire
1. Geometry modeling for simulation-driven design
Simcenter Inspire provides geometry tools that allow engineers to create, modify and prepare product concepts for simulation and optimization.
Hybrid modeling capabilities make it possible to work with different forms of geometry within the same workflow, supporting faster movement from an engineering idea to an analyzable design.
2. Early structural simulation
Design engineers can evaluate structural performance before the product definition is fully finalized.
Early structural simulation can help identify high-stress regions, excessive deformation and areas where material may not be used efficiently.
For companies that need structural analysis directly on complex CAD assemblies without a conventional meshing workflow, see
Simcenter Simsolid mesh-free structural simulation.
3. Topology optimization
Topology optimization is particularly valuable when engineering teams need to reduce mass while maintaining structural performance.
The engineer defines a design space, loads, constraints and objectives. Optimization then helps identify a more efficient distribution of material within the allowable design region.
A simplified workflow may include:
- Define the design space
- Assign materials
- Apply loads and boundary conditions
- Define optimization objectives
- Specify engineering constraints
- Run topology optimization
- Review the optimized material layout
- Refine geometry
- Validate the final concept

Simcenter Optistruct structural analysis and optimization.
4. Generative design and concept exploration
Instead of evaluating only one manually created design, engineering teams can use optimization and generative design techniques to explore multiple candidate solutions based on defined requirements.
The purpose is not to allow software to make every design decision automatically. Instead, these tools give engineers more technically informed alternatives to evaluate.
5. Design for manufacturability
A design that performs well in simulation is not automatically a good production design.
Simcenter Inspire therefore connects performance optimization with manufacturing-oriented workflows, helping engineers consider manufacturability earlier in the product-development process.
6. Motion simulation
Products containing moving mechanisms require engineers to understand relationships between geometry, joints, loads, displacement and dynamic behavior.
Motion simulation allows teams to evaluate mechanism performance virtually and improve concepts before investing in physical prototypes.
7. Fluid-performance exploration
Simcenter Inspire also extends simulation-driven design into fluid-related engineering workflows, enabling designers to evaluate how geometry changes may influence fluid performance during early development.
For advanced multiphysics CFD requirements, companies can evaluate additional specialized solutions within the Simcenter portfolio.
Typical Simcenter Inspire workflow
→ Define Engineering Requirements
→ Set Up Simulation
→ Evaluate Performance
→ Optimize
→ Compare Alternatives
→ Refine Geometry
→ Validate
→ Manufacturing-Ready Design
The key benefit is that simulation does not remain disconnected from design iteration.
Engineering teams can use simulation results as direct input for the next design decision.

How should a company evaluate Simcenter Inspire?
Instead of starting from a feature checklist, companies should begin with a real engineering problem.
A Proof of Concept can include:
- Select a representative component or assembly
- Define the current baseline
- Set an objective such as lower mass or increased stiffness
- Define loads and constraints
- Perform simulation and optimization
- Compare the optimized concept against the baseline
- Review manufacturability
- Measure potential workflow improvements
This helps answer the most important implementation question: Does Simcenter Inspire create measurable value within the company’s actual product-development workflow?
