    User efficiency

  • Geometry preparation with SimStudio Tools New

    Quickly modify, simplify, repair, and idealize your geometry for higher quality simulation models. SimStudio Tools reads in multiple CAD file formats and allows you to quickly eliminate unnecessary detail, create midsurfaces, perform basic repair, or easily make design changes so you can explore various design ideas faster.

  • MultiCAD import New

    Directly import and evaluate designs from software including AutoCAD, Inventor, Dassault Systèmes SolidWorks, Dassault Systèmes Catia, PTC ProE, and PTC CREO, and from file formats including NX, Rhino, IGES, and STEP. Once you have meshed a CAD model, a connection will be created and maintained between the CAD model and the Simulation Mechanical model. If the CAD package and Simulation Mechanical remain opened and if the CAD model is revised, the Simulation Mechanical model will be automatically surface meshed with the previous meshing settings after the CAD model is transferred. 

  • Interoperability with Inventor

    Associatively share data with Inventor. Import solid, surface, and weld geometry; 3D sketches; work points; materials; Inventor Simulation setup data; and part names and colors. Retain surface, edge, and part-based loads and constraints when you modify the CAD geometry. Edit Inventor parameters from within Simulation Mechanical. Perform automated parametric studies for convenient what-if and optimization analyses.

  • Easy-to-use interface

    Import models, set up and run simulations, and visualize and report results through a single, common user interface. Reporting tools automatically convert all user input and result views into a formatted HTML report that you can save as a PDF or Microsoft Word document.

  • Material library

    A built-in library with over 9,000 materials, from structural steels to reinforced polymers, helps you better understand the real-world behavior of products. It’s easy to add and manage custom data: Simulation Mechanical software integrates with MatWeb and Matereality, and manual entry and import options are also available.

    Finite element creation & analysis

  • Automatic meshing

    Generate meshes based on CAD solid or surface geometry from many sources, as well as on 2D outline sketches.

  • Structured meshing

    Use structured meshes to gain control over the size, shape, and quality of every element in the model. You can build structured meshes directly within Simulation Mechanical software—no solid or surface CAD model is needed.

  • Mixed model support

    Combine line, shell, and solid element types in a single model to solve complex assemblies more efficiently. You can combine element types such as brick, tetrahedron, truss, beams, rigid, actuator, pulley, membrane, and composite. Easily combine meshed CAD-based geometry and hand built finite elements. Use associative workflows with certain CAD software to easily perform what-if studies.

  • Pressure vessel

    Create pressure vessels and their components with the included PV-Designer. You can also use this tool to produce mesh that conforms to your analysis requirements. Use Simulation Mechanical software to simulate the performance of the vessel to help ensure that it satisfies requirements.

  • Composite parts definition

    Use failure criteria to address the layer-by-layer properties and fiber orientation of composite parts. Simulation Mechanical software works with Helius Composite software to help you decide which composite layout to use, and to analyze within the context of the overall assembly, including its various materials (steel, rubber, and other fibers and composites).

  • Autodesk Nastran solver

    Run more accurate and reliable simulations. The solver in Autodesk Nastran FEA solver software (included in Simulation Mechanical software) offers advanced analysis capabilities. Rigorous validation using NAFEMS, the Autodesk physical testing labs, and other published benchmarks help ensure the accuracy you need for dependable results.

    Mechanical analysis

  • Wide range of analysis types

    Investigate your assembly's response to vibration, thermal, and electrostatic loads, such as current and voltage.

  • Nonlinear structural analysis

    Use Simulation Mechanical software to understand when and why you would switch from a linear to a nonlinear analysis.

  • Vibration analysis

    Identify and eliminate linear and nonlinear vibration issues in your part or assembly. Meet seismic requirements by performing analysis types such as random vibration, harmonic, response spectrum, Dynamic Design Analysis Method (DDAM), and time history analysis. See stresses, deflection, and the factor of safety of your model under time- and frequency-dependent loads.

  • Mechanical Event Simulation (MES)

    Use this powerful nonlinear dynamic analysis tool to simulate and solve problems with drop test, impact analysis, and the metal forming of parts.

  • Thermal analysis

    Analyze thermal heat transfer using convection, conduction, and radiation effects. View temperatures and heat flow rates. Loads and results can be steady or transient. If they are transient, you can determine the change in temperature over a period of time.

  • Fatigue simulation

    Built-in fatigue simulation helps determine when and where products might fail. Perform stress- and strain-based fatigue analysis to determine product life and factor of safety. Simulation Mechanical software offers both high- and low-cycle fatigue options.

  • Parametric design study

    Analyze multiple variations of an Inventor 3D CAD model by manipulating its parameters within Simulation Mechanical software. Speed and simplify design iterations by analyzing ranges of dimensions and feature suppression.

  • Drop test analysis

    The Drop Test wizard makes it easy to set up a test scenario. Simply specify the height, gravity, direction, and other details.

  • Design optimization

    Determine optimal plate thicknesses and beam cross-sections with the Design Optimization utility, which automatically chooses the appropriate design dimensions. The utility works with all structures that contain beam or plate-type elements.

  • Dynamic Design Analysis Method (DDAM)

    DDAM is a type of shock spectrum analysis that estimates the dynamic response of a component to shock-loading caused by the sudden movement of a vessel. Use DDAM to analyze the shock response at the mountings of various shipboard equipment such as masts, propulsion shafts, rudders, exhaust uptakes, and other critical structures.


  • Combine analysis types

    Complete a number of different multiphysics workflows using Simulation Mechanical software. Set up advanced simulations easily with standard engineering terminology, visual process guidance, and user-friendly tools and wizards that transfer simulation results between multiple analyses. Help designers, engineers, and analysts focus on product performance, rather than advanced numerical or simulation methods.

  • CFD interoperability

    Apply pressure and temperature results from CFD software to simulate thermal and flow stresses (fluid structure interaction) on your mechanical components. After completing your flow simulation, launch the CAD model in Simulation Mechanical software, assign the settings to define the thermal stress analysis, and select the CFD design study file as the temperature source.

  • Moldflow interoperability

    Validate and optimize plastic part designs. Exchange data, including fiber orientation and residual stress, between Moldflow plastic injection molding simulation software and Simulation Mechanical software.

    Simulation results & data management

  • Stress linearization New

    For linear static stress analyses, define a customizable Stress Classification Line (SCL) and perform stress linearization based on ASME Boiler and Pressure Vessel Code (Section 8 Division 2). Determine local stress tensors along the SCL and the resultant bending and membrane stress intensities. Output is based on both the Von Mises and Maximum Shear stress combination equations.

  • Factor of safety

    Analyze and output the factor of safety of every linear design based on the strength of the material for each component. The allowable stress is predefined for most library materials, but you can also choose your own allowable value.

  • Detailed reports

    Quickly create reports with a cover page, table of contents, material information, boundary conditions, mesh properties, and analysis results, including images and animations. Choose from a variety of output formats. 

  • Vault integration

    Vault data management software is embedded in the Simulation Mechanical interface. Use it for search and revision control, as well as to help secure your intellectual property.

  • Advanced visualization

    Integrate with other Autodesk products to help create high-end renderings. Use FBX files to export results to visualization tools such as 3ds Max 3D modeling software and VRED 3D visualization software, or transfer data directly to Showcase 3D presentation software.
