Rigid body modes, part 2

“

- [Instructor] Now, in this video, we're going to introduce deliberately some rigid body modes. And we can see this time we've got an assembly, and the same assembly as we had before. We've got two parts, the box and the plate. We're going to deliberately disconnect the first time, and then connect them up and see the difference between them. So we've opened up the part, we can see the box, we can see the plate. So we go to the Environments, go to Autodesk Nastran In-CAD, here's our tree view. Let's change this straight away into a normal modes analysis, and I'm going to just deselect reactions and stresses. We're going to change the material, as usual, to our standard steel, carbon steel, and click OK. Next job, we're just going to check the metal setup. 10 frequencies is fine. Again, remember my constraints. Going to pick the same measures we've been using throughout this series of exercises. We select the face, and we allow it to be fully constrained. At this point, I can mesh, and…
