Hi,

 

I wonder why we use an OFFSET for the objective = Compliance  in a Topology optimizationto have more iteration before that the result converge? 

this is usually used if we want to optimize a small componant attached to a big domain 

 

 

In the picture i show the new axis ( in red ) after an offset equation 

Thank you
