Warning Message: Probable reduction of the model is more than …% of the starting model.
This warning shows, that the chosen settings result in a high material loss and this is probably not reduction. This might not be what the user wantsanticipates. The %-value is an estimation of the volume reduction at the end of the optimization process . So it is an estimation of the amount of volume reduction between the starting design and of the iteration 64 considering the stress goal.The considering the chosen optimization setup.
If the design space is chosen very large in comparison to the boundary application points the user will expect such a behaviour and the optimization is exactly doing what it’s supposed to be.
If the design space is not that large, the model setup is probably not chosen very well
...
. There might be huge differences between the amount of forces and the
...
defined stress goal.
...
Have a look at the stresses and adjust your optimization setup because the optimization will most likely not result in the expected
...
geometry. Find information on how to change the parameters here.
...
Additionally, the model setup can result in a lost connection to the nondesign spaces
...
and therefore boundary conditions. In this case the optimization will
...
produce an error and
...
terminate the run. Please see the error

The warning regarding the lost percentage was implemented to help the user choose better settings and is a kind of early warning system for the user, that the chosen parameters are not well selected and that the optimization will not end in a satisfactory result in most casesat an early stage in the optimization to evaluate the optimization and choose better settings.
