In the optimization task editor, click the Basic
tab.
Choose whether to respect boundary conditions that have been applied
to the model.
It is recommended that you freeze regions to which boundary
conditions are applied because you do not want these regions to be moved during
the optimization. Freezing these regions stabilizes the optimization and often
leads to a significantly lower number of iterations.
By default, the
Optimization module
freezes boundary conditions for the whole model. If desired, click
 and select the region in which the boundary conditions should be
frozen.
