Autodesk Inventor Nastran: Finite Element Analysis (FEA) Software in Inventor
Autodesk Inventor Nastran is finite element analysis (FEA) software built into Inventor for nonlinear, dynamics, heat transfer, and fatigue studies. Get it in the Product Design & Manufacturing Collection from Hagerman, with ongoing support from our team and live Inventor Nastran courses available. With Inventor Nastran, you can:
- Simulate your Inventor parts and assemblies without leaving Inventor
- Run linear and nonlinear stress, dynamics, fatigue, and heat transfer studies with the Autodesk Nastran solver
- Test real-world conditions with drop tests, bolt connectors, and advanced material models for metals, rubber, and soft tissue
- Trust results from a solver verified against NAFEMS benchmarks

What is Autodesk Inventor Nastran?
Autodesk Inventor Nastran is finite element analysis (FEA) software that runs inside Autodesk Inventor. Designers and engineers use it to predict how parts and assemblies will behave under real-world loads, heat, vibration, and repeated use, and fix problems before building physical prototypes.
It's powered by the Autodesk Nastran solver and goes well beyond the linear static and modal studies in Inventor's built-in Stress Analysis, adding nonlinear, dynamic, fatigue, and heat transfer studies.
Inventor Nastran is included in the Autodesk Product Design & Manufacturing Collection. It isn't sold on its own.
Why Use Inventor Nastran?
Improve Product Performance
Choose from a complete portfolio of powerful study types to help you optimize your design.
Reduce Warranty Issues
Go beyond linear static study types and analyze the effects of recurring loads in a fatigue study.
Decrease Time to Market
Analyze your designs early and often right inside Inventor to reduce the number of physical prototypes.
Inventor Nastran Capabilities
| Capability | What it does |
| Linear and nonlinear stress | Analyze stresses and deformation, including nonlinear material behavior |
| Advanced material models | Simulate metals, rubber, and soft tissue in one simulation, with plasticity, rubber, and soft tissue models in nonlinear studies |
| Heat transfer | Analyze convection, conduction, and radiation to avoid overheating, then use the results in thermal stress studies |
| Automated drop test | Set initial velocity and acceleration to simulate impact |
| Dynamics and response spectrum | Run dynamic studies, including response spectrum analysis with modes, damping, and spectrum data |
| Bolt connectors | Connect assembly parts with bolts to check fastener loads and reduce bolt count |
| Static fatigue | Predict durability under repeated loading, including low- and high-cycle fatigue |
Inventor Stress Analysis vs. Inventor Nastran
| Inventor Stress Analysis | Inventor Nastran | |
| Included with | Product Design & Manufacturing Collection | Inventor Professional |
| Study types | Linear and nonlinear stress, dynamics, fatigue, heat transfer, drop test, and more | Linear static and modal |
| Best for | Validating designs under real-world conditions before prototyping | Quick checks while designing |
| Where it runs | Inside Inventor (separate install) | Inside Inventor |
Many teams start with Stress Analysis for quick design checks and move to Inventor Nastran when they need nonlinear materials, fatigue, heat, or impact. If you have the Product Design & Manufacturing Collection, you already have both.
