Autodesk Inventor Nastran is an advanced CAD-embedded Finite Element Analysis (FEA) simulation software powered by the industrial-strength Autodesk Nastran solver. It runs directly inside the Autodesk Inventor design interface, allowing engineers and designers to perform high-tier virtual stress, thermal, and dynamic testing without converting or exporting their 3D models.

Key Features

The primary benefit of Inventor Nastran is its deep simulation portfolio embedded directly within a mechanical modeling environment.

1. Broad Structural Analysis Typologies

• Linear & Non-Linear Static: Analyze structural deviations under constant loads. While linear math assumes materials return to shape, the advanced non-linear engine tracks permanent plastic deformation, large geometric displacements, and hyperelastic materials (such as rubber).

• Buckling Limits: Evaluates thin-walled or slender structures under compressive forces to find the critical load point where sudden catastrophic structural collapse occurs.

• Pre-Stress Static & Normal Modes: Computes natural structural frequencies and vibration harmonics on components already experiencing structural tension or compression (such as a spinning turbine blade or a tuned guitar string).

2. Dynamic & Impact Simulations

• Transient & Frequency Response: Track structural shifts over a specific timeline or across a sweep of continuous physical frequencies.

• Random Vibration & Shock: Simulates how structures respond to random forces over a set lifespan (essential for aerospace, automotive structural assemblies, and electronics transport testing).

• Automated Impact Analysis: Simulates high-velocity drop tests and real-world kinematic impacts between bodies without manually configuring highly complex multi-stage explicit solvers.

3. Thermal Analysis & Advanced Materials

• Steady-State & Transient Heat Transfer: Tracks thermal flow paths, convection conduction, radiation, and dissipation across assemblies over time.

• Thermal Stress: Simulates how components warp, expand, or structurally crack due to intense internal heat or uneven temperature zones.

• Composite Layering: Engineers and maps high-performance multi-layered carbon fiber, fiberglass, and laminated structures using advanced orthotropic material properties.

4. Advanced Interaction Mechanisms

• Surface Contact Types: Models how parts interact across assemblies with real-world accuracy using diverse boundary rules, including sliding contact, separation, interference fits, and permanent bonding.

• Bolt & Connector Wizards: Simplifies complex mechanical assemblies by replacing solid modeled bolts, pins, and springs with highly efficient, mathematically equivalent line elements that speed up simulation calculations.

System Requirements

Because Inventor Nastran is an add-on utility, you must have a full 64-bit version of Autodesk Inventor (Standard or Professional) installed on the local system machine before installing Nastran.

The software uses your local computer hardware to solve large simultaneous equations, so system performance scales directly with your hardware specs.

1. Operating System

• Supported: 64-bit Microsoft Windows 11 and Windows 10.

• (Note: If you run the standalone command-line "Autodesk Nastran" engine without the graphical user interface, Linux RedHat Enterprise 8.6+/9.0+ and Rocky/AlmaLinux setups are supported).
