I'm trying to optimize a 'building'. SPCD are applied as an acceleration at the base of the structure.
Responses:
volumefrac
frf displacement - dof1 @ top of structure @ 3.2Hz
dconstraint
displacement constraint - 0.015 (analysis shows displacement = 0.01752 @ 3.2Hz
objective
min (volumefrac)
optimization
the optimized shape does not look right. by eliminating the element densities, the entire model disappears. I'm not sure if i am doing something wrong?
