Subject: STRUC-Substructuring for Transient
Author: Tom Davis
Date: 2002-05-22 12:14:00

I am trying to do a transient analysis with substructuring. There are two
load steps. The first load step is strictly for applying an initial
velocity which I do with D and TIME commands. As per the manual, I have to
DDELE the displacements from the first load step when I start the second
load step. HOWEVER, there is a small note in an example problem in section
5.3 of the manual that says D and M may not change between load steps.

So, how can I apply an initial velocity and then move to my second load
step without changing D? The manual also talks about using IC to specify
initial velocity. I'm not sure I understand how to do this. Do I use the
"value2" field to specify velocity? If so, could I then use IC and skip
the first load step?

Any and all suggestions appreciated.

Thanks.
