hi,

is there a way to impose velocity on nodes in optistruct? when i go into the constraint panel there are a lot of load types, but i don't reaaly understand what each of them mean.

thx

    Hi Phil

     

    You can specify enforced motion using SPCD (in constraints panel) and refer the same in TLOAD1/RLOAD1 with a time/freq dependent table (TABLED1)

    SPCD is immposed displacement? if so what's the difference between SPC and SPCD, i already tried using SPCD but when i do i get an error (no imposed load or displacement).

    Hi Phil,

     

    Please see the description below:

     

    SPCD can be used to define enforced velocity. You need to select the appropriate load type in dynamic load card.
