Warning "The following component is not considered in this iteration:" makes you aware if one nondesign space is not considered in the optimization/in the iteration
Reasons for the Nondesign to tear off:
either no force or displacement is applied → no stresses are available for the stress optimization
or the force applied is too small
Solution possibilities:
Either it is a design proposal you can accept/even want to reduce the number of connecting points
Otherwise prevent the tearing off by:
set down the optimization stress goal
creating an extra load case in which fixations and loads are switched
increasing the force so that the stresses and therefore the relevance of the nondesign space is increased
increase the complexity → more elements are available and a finer model is possible (takes more time)
If you are using the symmetry function and have setup the whole model, the optimizer won't use the symmetrical nondesign spaces and will notify you thereof - don’t worry everything is just as it is supposed to be
