Start rough, and use the analysis through each phase of the design to steer towards the final acceptable product. This increase followed suit with my intended design plans. As I added features, Inventor increased the feature detail accordingly, and as a result, the accuracy increased, as well as a proportionate amount of time spent in analysis. Using this staged approach I harnessed Inventor’s adaptive meshing to my benefit: In the beginning the feature complexity was reduced, and Inventor dropped the detail in the analysis accordingly, and as a result, the accuracy dropped in favor of speed. I used numerous mesh settings and refinements to verify the model I submitted (more on that later). Inventor reacts to the features as they are incorporated into the model being analyzed. Here the mesh element count has grown 5X, resulting in moderate detail and as a result, significantly more refinement of the analysis. Look at how the mesh has adapted to the additional curved features, and how the longer elements have adapted near the transitions. Adding the Structural Fillet Featuresįinally, the fine details and corner rounds are added. Moving ahead, the same settings are held, but watch what happens to the mesh. If you review your mesh, you might miss something this simple, and the analysis would be pointless. The results are considerably different, and should hopefully command a little respect, even when performing a fast set of approximations. While the one on the right is quite rough, and incapable of accuracy in certain aspects of analysis, the one on the left is a tragedy, and should immediately prompt anyone to check their settings. Very Rough Results to close gap on where the tuning should BEGIN

Model fillets have not been applied either. In the following images I’ve incorporated the default Inventor settings, average 0.1 / minimum 0.2, 1.5 grading factor, and 60° minimum angle. Let me show you an example that might help you see how important this is. Keep this in mind when evaluating your mesh settings on parts that will have features added in and removed repeatedly. The mesh is adaptive to a feature’s size and contact surfaces. While Autodesk has made these features easier to use, serious considerations should be made prior to depending on the results. NOTE: Mesh and Analysis are areas that require substantial amounts of study and understanding.

Turn on the mesh view (button on the Stress Analysis Ribbon), and update the mesh if necessary. Ignoring the mesh is like eating something that someone else made, and not looking at it first. Inventor employs an H-P mesh that’s fast and adaptive, but it’s not going to size the mesh for you. The entire process is run on a mesh that is developed from the component model, not the model itself. While using stress analysis is fairly easy, there are a load of options and possibilities that can be overlooked.
