Tip: boundary conditions such as constraints and the like can be applied to different subsets Meshing
Geometric entity (by edge of selected geometry). Individual component coordinate systems (X,Y,Z axes). Tips: Autodesk suggested using Welded for ‘Bonded’ types, and General for most other applications. Various limitations to contact proximity, penetration, etc. no rotation, free, symmetry, etc.) that directly relate to the 6 degrees-of-freedom check boxes that most analysts relate to.ĭiscerning between various surfaces is handled through the Inventor alternate surface explorer popup.ĥ Contact types are available: General, Slide, Welded, Rough, and Offset Weld. The Constraints dialog also contains buttons that identify limiting concepts (i.e. 
Once selected, the particular conditions can be configured and applied as required. Tip: Non-linear material types are supported, but will need to be created as these definitions are not in the existing Inventor Library (as far as I know).Ĭonstraints, Contacts, and Loads all use similar dialogs that permit faces and bodies to be selected and deselected as desired. In addition it can import material properties from any of the Inventor or Autodesk material libraries, or allow users to create their own. It will pull in the material properties from the CAD model with the push of a button. Nastran In-CAD sorts components into material categories that are easily defined. … a laundry list of review and comparison to ensure that you are confident in the analysis model and results.
Adjust the model and rectify and oversights.Establish materials, boundary conditions, and loads.The setup workflow is the same as one would expect:
I am however writing this for everyone’s benefit, including existing Inventor users that are considering a Nastran solver. It should be noted here that Autodesk is selling In-CAD directly with Autodesk Inventor, as if to say “Here is our Nastran solver with an Inventor front end”. (I should mention that I crashed an In-CAD seminar at Autodesk University for about an hour, so I did have an hour jump-start) I thought that this article would be a good time to get in and try it from the perspective of a new user. While I have had some experience with Siemens FEMAP interface for Nastran, I have had very little experience with Autodesk’s new In-CAD UI.
Analyze structures, such as columns and beams, for catastrophic failure under certain loading conditions.Recently I reviewed the features that Autodesk Nastran In-CAD offered to inventor users that wanted a lot more simulation power. Avoid assembly failure due to high thermal stress. Select which structural members will be automatically idealized as beams. Import data from Autodesk CFD, and apply thermal and fluid pressure results. Resolve problems with noise and vibrations. Determine stress, strain, and deformation. Model metals, rubber, and soft tissue in a single virtual test. Automate projectile impact and virtual drop tests for phones, laptops, and many other products. Go beyond the linear static studies in Inventor with embedded FEA technology. Use robust and accurate CAD embedded analysis capabilities. Features of Autodesk Inventor Nastran 2022 This is to get a better understanding and a stronger confidence in the draft design proposal. This program Nastran In-CAD can also handle different types of elements in the same analysis, that is, mixing surface models with solids or beam elements in the same analysis. The new Nastran In-CAD offers a wide range of simulation spanning across multiple analysis types, delivering another high-end simulation in a CAD-embedded workflow that works within both Autodesk Inventor and SOLIDWORKS to help engineers and analysts make great products. Description Autodesk Inventor Nastran 2022 OverviewĪutodesk Inventor Nastran is a CAD-embedded, general-purpose FEA tool powered by the Autodesk Nastran solver.
