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

[Dr. Daniel Winarski]

Hi, Sir, I think I have figured this out. I assign an initial displacement ONLY for the toroidal drop mass.  Then I assign a small time step in STEP-1 of setup, so that displacement/time = -3.866ms.  Then, I proceed with STEP-2 in setup with free motion of the overall system.  Does this somewhat terse assessment sound reasonable to you?  Thanks!
