Mass participation example
- [Instructor] In this video, we're going to run the normal modes analysis of a lamppost structure, and then we're going to check out the model effect of mass contributions. I'm going to open the part which is the lamppost part. This is a solid model, and it's made up of various bodies which have been split, mainly so that we can get good meshing, and also get positioning of the lump masses which represent the lamp positions. We go to the Autodesk NASTRAN In-CAD environment. What I'm going to do first off before we do anything else is to save the model, again with the run name I want for the NASTRAN run into the directory structure I want to see the NASTRAN result for how it's going into. I have a run area. I'm saving it into the run area. Go into the environments, and then the Autodesk NASTRAN In-CAD environment, and then we can see the default Linear Static Analysis. I'm going to change that to my Normal Modes Analysis. Make sure I'm only outputting displacements. Go and load in our…
