Fig 1: Project Schematic

With the release of Mechanical 19.2, substructuring is now available for Modal & Rigid Dynamics without scripting. That just made my earlier post on CMS outdated! Note that there is still a key limitation where Generation and Expansion Pass must be performed on your local machine.

To get ahead of the game a bit, here is a way to do Harmonic Analysis extending on previous work. (Please go through that before this post). Some points of note:

The method of merging the CMS and non-CMS models together into System C is the same.All files related to the superelement has to be copied over to the solver file directory as before.Modal analysis need not be performed first as the example here uses Full Method instead of Modal Superposition for simplicity. The script expands the responses the same way as Modal Analysis does so the script will look familiar.
