Topology Optimization: Large Deformation wanted, modify objective/constrains?

  Hey,
  i'm currently working on a project in which i need a part to be optimised in a way that a certain surface moves a largamount (at least 3mm, perfect would be more then 10mm). Is there a way to modify the topology objective and restrictions to reach this objective?
  The picture shows one attempt where the deformation criteria was achieved but in the very net iteration some error occured and the main objective (compliance) malfunctioned.
  Another solution would be to extract the last successfull iteration, which was actually perfect for my project. Is there a way to do so?
  Or is it possible to somehow deactived or make the objective "compliance" less important, as it somewhat contradicts my actual main objective of given deformation?
  Thank you in advance,
  Paul

  Large deflection is not supported in Ansys. Please refer to the discussion below:
