Simulation Mechanical

Finite element analysis and modeling software

Simulation Mechanical software helps engineers easily set up advanced simulations so they can create better products. The software provides a wide range of advanced mechanical simulation tools. Powerful features include Mechanical Event Simulation (MES), Autodesk® Nastran® FEA solver software, multiphysics simulations, multiCAD format support, cloud-solving options, and composites.


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, planar, and solid element types in a single model. You can combine other element types as well, such as trusses, beams, membranes, composites, rigid elements, and actuators. Assemblies containing thin components such as sheet metal solve efficiently using shell elements. With Simulation Mechanical software, you can use solid and shell elements in the same analysis.



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 Simulation Composite Design 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, now included in Simulation Mechanical software, offers advanced analysis capabilities.



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. Setting up advanced simulations is easy thanks to standard engineering terminology, visual process guidance, and user-friendly tools and wizards that transfer simulation results between multiple analyses. This helps designers, engineers, and analysts focus on product performance rather than advanced numerical or simulation methods.



Simulation CFD interoperability


Apply pressure and temperature results from Simulation 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 Simulation CFD design study file as the temperature source.



Simulation Moldflow interoperability


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



Simulation results data management

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


Create reports with a click of a button. Reports have a cover page, table of contents, material information, boundary conditions, mesh properties, and the results of the analysis, including images and animations. You can 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 import 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.



User efficiency

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.



MultiCAD import


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.



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.



Flexible cloud solving options


Extended solving options let you simulate locally or in the cloud, depending on your needs. If you are testing the setup of an analysis, use your local machine to iterate and optimize. When you are ready to initiate a longer, more computationally intensive simulation, use the power of the cloud, saving local resources for other tasks. Compare Simulation Flex vs. Desktop offerings.
