Finite element analysis and modeling software

Simulation Mechanical software, featuring integrated Autodesk Nastran FEA solver software, provides fast, accurate, and flexible tools for finite element analysis and modeling. Whether you’re a designer, engineer, or analyst, Simulation Mechanical helps you predict product performance, optimize designs, and validate product behavior before manufacturing. It’s part of the Digital Prototyping solution.

Simulation Mechanical features

Mechanical simulation tools

Demos show how you can use Simulation Mechanical tools to perform fatigue and impact analysis. Powerful features help you solve design problems and define composite parts. Flexible options let you solve on your local machine and use the cloud for additional solving capacity.


Autodesk Nastran solver
Run more accurate and reliable simulations. The solver in Autodesk Nastran software, now included in Simulation Mechanical software, offers advanced analysis capabilities.


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.


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.


Simulation Moldflow interoperability
Validate and optimize plastic part designs. Use tools to exchange data, including fiber orientation and residual stress, between Simulation Moldflow and Simulation Mechanical software.


Wide range of analysis types
Investigate your assembly’s response to vibration, thermal, and electrostatic loads, such as current and voltage.


Mechanical Event Simulation (MES)
Use this powerful nonlinear dynamic analysis tool to solve problems including drop test, impact analysis, and the metal forming of parts.


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, etc.).


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.


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.


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.


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 and VRED software, or transfer data directly to Showcase software with the click of a button.
