Reply To: Declaring initial velocity in spring-mass system using Transient Structural

[Dr. Daniel Winarski]

Hi,

This is the link to my T3.wpbz “archive” file and an explanatory paper (in draft form):

https://drive.google.com/drive/folders/15hk0CkyCsw6xtd0LeRArVkMZfuM3YWAc?q=sharedwith:public%20parent:15hk0CkyCsw6xtd0LeRArVkMZfuM3YWAc

You don’t have to read the entire "draft" paper…..however, the figures may prove instructive. Figures 5 and 6 show the advice you generously gave me about dropping transient structural into the solution cell of modal. 

Where I am stuck now is on Figure 7, where I would like to specify an initial condition (IC) of velocity on ONLY the toroidal-shaped drop mass (shown in green).  This V(T=0) initial condition would be -3.866m/s, downward along the vertical “Z” direction. The goal then is to document the rebound of the drop mass, and how much of the initial kinetic energy of the drop mass is transferred to the basketball rim, backboard, and frame.  I sincerely apologize that I could not figure this IC out for myself.

Please allow me to point out that this work has no external funding or support of any sort.  Once published at the authors' expense, this will be publicly available at no cost what-so-ever to any and all readers.

Thank you so very much, Daniel Winarski
