GRAB THE BENEFITS OF AUTODESK INVENTOR NASTRAN

Autodesk Inventor Nastran embedded with FEA Technology is a mechanical simulation tool, which was developed by Autodesk Inc. USA. Initially, the Nastran software was developed for NASA but now adopted by Autodesk as well which offers FEA simulation capabilities. This software simulates the mechanical structures and analyze the environmental conditions in order to check the responses of the structure. This tool is useful to simulate the linear and nonlinear FEA studies.


Apart from general engineering materials, Nastran can also be used to simulate and analyze the latest advanced materials, including composites, plastic, nonlinear elastic, shape memory, hyperelastic, viscoelastic, and brittle materials such as concrete.


It considers the unit system from the CAD, which is attached to the simulation, or else you can also set the units as per the requirements.

If we talk about the number of analyses capabilities, which we can perform, using Inventor Nastran then it supports a wide range of it. First, it is important that you understand the requirements, outputs, and limitations of the analysis type before using it. You can perform the below analysis types by using the software such as;
  1. Linear Static
  2. Normal Modes
  3. Linear Buckling
  4. Prestress Static
  5. Prestress Normal Modes
  6. Nonlinear Static
  7. Nonlinear Buckling
  8. Direct Transient Response
  9. Modal Transient Response
  10. Nonlinear Transient Response
  11. Direct Frequency Response
  12. Modal Frequency Response
  13. Random Response
  14. Shock/Response Spectrum
  15. Multi-Axial Fatigue
  16. Vibration Fatigue
  17. Linear Steady State Heat Transfer
  18. Nonlinear Steady State Heat Transfer
  19. Nonlinear Transient Heat Transfer


Inventor Nastran has also enabled the solution for contact analysis; you can set the contact type and tolerance, performance connectors simulation such as bolt etc.. This gives you the power to optimize the mesh to obtain the accurate results.


You can generate the line mesh, which can be used in uniform cross-sectional structures, mid surface mesh and shell mesh for sheet metal parts and solid mesh to generate the solid elements in the structure.

Meshing is the critical operation in FEA so it must be done with real scenarios in the study. In Finite Element Analysis, mesh size is very important; it is closely related to the accuracy and number of the element required in the mesh. By increasing the elements in the simulation, you get better and better results but once you get the optimum size of the mesh to obtain accurate result, it will not effect or difference is very less in the results more an less, you cannot change the other parameters of the simulation.  In other words, keep refining the mesh until you see no difference in your results.



The best part of this product is, Autodesk provides the subscription based licensed for this software at a very economical price. User can subscribe the license based on the need and work, so there is no extra cost for the product. It helps a lot to the independent consultant in order to offer their services at minimum cost. User can opt for the monthly or yearly subscriptions.



Autodesk Inventor Nastran is available as a standalone and network license, which provides consistent user experience, eliminate the need for multiple simulation technologies and delivers CAD-embedded workflow. In this, you can manage the license, transfer the license and it available only in the Product Design & Manufacturing Collection. To try the software capabilities you need to download the Inventor Nastran software and use its trial version free of cost.  For downloading the software use the below given link and you can also extract the price information details, system requirements, OS etc. as per needs.
