Autodesk Inventor Nastran 2026.2: Advanced Simulation Inside Inventor

Autodesk Inventor Nastran 2026.2 is the latest update of the powerful, CAD-embedded Finite Element Analysis (FEA) software. It brings the robust solver technology of NASA's Nastran directly into the Autodesk Inventor environment, allowing engineers to perform advanced simulation without leaving their design workspace.

Key Features & Capabilities

1. Seamless CAD Integration

• Fully Associative: The simulation model is directly linked to the Inventor CAD geometry. Any design change automatically updates the simulation setup, enabling rapid design iteration and "what-if" studies.

• Single-Window Workflow: Run complex analyses without the need for file translation or switching between different software applications, streamlining the entire validation process.

2. Comprehensive Analysis Types

• Linear and Nonlinear Stress Analysis: Predict deformation and factor of safety under static loads, accounting for large deflections and material plasticity.

• Dynamic Analysis: Perform modal, frequency response, and random vibration analysis to understand how your design behaves under dynamic loads.

• Heat Transfer & Thermal Stress: Simulate steady-state and transient thermal loads and their resulting stresses.

• Buckling & Advanced Dynamics: Predict buckling failure and analyze complex events like impact and shock.

3. The Power of the Nastran Solver

• Proven Technology: Leverages the same solver trusted by aerospace, automotive, and defense industries for its accuracy and reliability.

• Advanced Materials & Elements: Model complex material behaviors (composites, hyperelastic, creep) and use a wide range of element types for high-fidelity results.

4. Enhancements in the 2026.2 Release
This specific update (2026.2) focuses on:

• Improved Solver Performance: Faster solution times for large and complex models.

• Enhanced Contact Automation: More robust and easier setup of contact conditions between parts in an assembly.

• Workflow & Usability Refinements: Streamlined menus and more intuitive controls for setting up studies and interpreting results.
