What is Simcenter Inspire?
Simcenter Inspire, formerly Altair Inspire, is a CAE tool from Siemens Digital Industries Software built for designers. It brings simulation into a CAD-like environment and combines geometry modelling, generative design and manufacturing simulation, so you can explore concepts, check performance and assess manufacturability early in the design process.
Combine BRep, PolyNURBS, facet and implicit geometry, with lattices, in one model
Study structural, motion and flow performance with embedded solvers that remove or automate meshing
Generate concepts early with topology optimisation, then refine and validate them in Simcenter OptiStruct

Coming from Altair Inspire?
Siemens has renamed Altair Inspire and moved it into Simcenter. The changes focus on naming, packaging and integration; in essence, Siemens says, it is the same technology. See what the other former Altair tools are called now.

Capabilities
From first shape to a part you can make

Topology optimisation that follows the loads
Set the design space, loads and goal, such as maximum stiffness or minimum mass, and topology optimisation removes the material the part does not need. Draw directions keep the shape castable, stampable or extrudable, and an overhang control makes it more self-supporting to print. Then fit PolyNURBS to the result.Customer result87% lighter robot brackets and 94% lower annual repair costs. Würth Industrie Service

Test strength, motion and flow early
Structural analysis runs on the SimSolid or OptiStruct solver, mechanisms can be rigid or flexible bodies, and motion results can be extracted for structural analysis and optimisation. Inspire Fluids adds steady-state flow and heat transfer for design exploration.Customer result18% lighter aluminium profile, validated in Simcenter SimSolid, with a 40% shorter design cycle. Faraone

Check it can be made
Inspire Cast simulates filling, solidification and deformation for gravity, high- and low-pressure casting. Inspire Form, Mold, Extrude, Polyfoam and 3D Print cover stamping, injection moulding, extrusion, foam parts and additive manufacturing, each as its own Inspire product.Customer result53% lighter cast harvester boom end, with porosity found and fixed in an Inspire Cast check.

How is Simcenter Inspire licensed?
We quote each set-up individually. According to the Simcenter Inspire 2026.1 user guide, Inspire’s solvers either draw Altair Units from a managed licence or a licence server, or run as features of a standalone licence, and Siemens names process tools such as Inspire Cast and Inspire Form as products of their own. Tell us how you license Inspire today, the tools you use and your renewal date, then request an Inspire licence quote.
What changed for Altair Inspire users?
Siemens completed the acquisition of Altair on 26 March 2025. With the June 2026 release, Altair Inspire became Simcenter Inspire, and tools such as Inspire Cast and Inspire Form carry the Simcenter name too. Altair’s support services have moved to the Siemens Support Center, and from December 2026 Simcenter products get two major releases a year. If you bought Inspire through Volupe, your Volupe contacts for licensing, support and training stay the same.
How does Simcenter Inspire compare with Simcenter OptiStruct and SimSolid?
They cover different stages. Siemens says Inspire makes generative design accessible to design engineers without deep FEA backgrounds: it generates optimised concept geometry early, and Simcenter OptiStruct refines and validates those concepts later. According to the product documentation, structural analysis in Inspire can use OptiStruct or SimSolid, but SimSolid is for analysis only, not optimisation, and inside Inspire it covers linear static and modal analysis; standalone Simcenter SimSolid covers more analysis types. If you are new to the terms, our guide explains the difference between topology optimisation and generative design.
Which manufacturing processes can Simcenter Inspire simulate?
Each process has its own Inspire tool. For casting and stamping, core Inspire has basic porosity and thinning checks; according to the documentation, Inspire Cast handles basic, gravity, high-pressure and low-pressure processes. Siemens says Inspire Form’s feasibility module predicts formability in seconds and its tryout module simulates multi-stage forming, trimming and springback. Inspire Mold targets warping and sink marks in injection-moulded parts; Inspire Extrude, Polyfoam and 3D Print cover extrusion, foam parts, powder bed fusion and metal binder jetting.
Can Simcenter Inspire simulate motion and fluid flow?
Yes. According to the documentation, Inspire Motion simulates mechanisms as rigid or flexible bodies, with joints, motors, actuators and springs, and you can extract its results for use in structural analysis and optimisation. Inspire Fluids is a design exploration tool for steady-state, single-phase flow and heat transfer, on a voxel-based solver that needs no traditional CFD mesh. Siemens says the June 2026 release adds real-time geometry editing. For transient or multiphase flow, Volupe also supports Simcenter STAR-CCM+.
Which CAD formats and operating systems does Simcenter Inspire support?
According to the Simcenter Inspire 2026.1 user guide, Inspire imports CATIA V5, NX, Creo, SolidWorks, Inventor, JT, Parasolid and STEP files, among others, converts third-party formats to Parasolid where needed, and opens and saves files in Siemens Teamcenter and PTC Windchill. It runs on 64-bit Windows 11, Red Hat Enterprise Linux 9.6 and Rocky Linux 9.6 with at least 16 GB of RAM; the Print3D tab and the porosity check are Windows-only, and rendering needs a dedicated GPU that supports Vulkan 1.2 (AMD, Intel Arc or NVIDIA; onboard Intel graphics are not supported).
Does Volupe offer Simcenter Inspire training and support?
Yes. Our simulation engineers answer technical questions from Inspire users: ask our engineers. Volupe sells, supports and trains every former Altair tool; Simcenter Inspire is not among the scheduled courses on our training page, so tell us what your team needs and we will come back with options.
