Join Tony Abbey for an in-depth discussion in this video What you should know, part of Autodesk Nastran In-CAD: Dynamic Analysis.
- [Instructor] Now in this video I describe what you should know for the course, and what you would need to come on the course. So what you should know is a basic familiarity with Autodesk Inventor geometry. If you're familiar with CAD and the CAD interface, that's a fantastic start for you. So now it's a transition or migration into the analysis world. You also need a basic awareness of engineering concepts. Some familiarity with FE analysis would be useful. But no particular Dynamics knowledge is assumed. I'm going to build up, really from ground up.
And what you should have is the Autodesk Nastran In-CAD Add-In into Autodesk Inventor. All the dynamic analysis types are supported in the Add-In, and also, a separate unbundled Nastran solver in Editor as well, just for good measure. Now you're going to need version 2019 or later to open the Autodesk Inventor part files. Anything earlier than that and it will refuse to open it. However, what I've done is to provide Parasolid geometry files in the exercise folder if you don't have version 2019 or later.
Basically, I stick to a very simple geometry, which is a simple plate, and you'll be able to import that. I've also given the dimensions of that so you can build it from scratch. I only have a couple models which are a little bit more exotic. I've tried to deliberately base everything on simple geometry, because of past experience where if I put too complicated geometry in, people can't build it, they can't import it with earlier versions. So, you should have a fairly straightforward ride as far as the geometry is concerned. For the various exercise that require FE entities, you're going to have to build up your own suite of those if you don't have version 2019 or later.
But if you follow through the exercises, then you should be able to build up a portfolio of those Inventor parts, which now have FE entities embedded in them, as it were.
