Hi,
In the case of sub-components forming part of a global structure, the contribution to the total compliance of the subcomponents can be very small, even if the surrounding structure is condensed into a super-element. This contribution can be detailed by calculating the deformation energy of the elements constituting the subcomponent.
and this is my problem right now, i want to optimize my Design_Space ( in red ) with objective minimze compliance and Cstr= Volfrac=30%
but the compliance of my design space = 3E+2 and the total compliance=6e+7, so it's negligible. so i tried to use an OFFSET of the objective, i tried to use a LOG equations to make the difference between the two compliances in the same scale.. but all that didn't work ! There is a solution to have a result please ?
Best
