About Constraints

Constraints provide limits on the target of your optimization. For example, you can configure the optimization to minimize the mass of the design space and apply a constraint that limits the maximum stress in the model.

You can select from the following constraints:

Option Description
Frequency Constraint The minimum frequency of selected modes cannot fall below a specified value, and the maximum frequency of selected modes cannot exceed a specified value. You can apply only a single frequency constraint to your model.
Note: You cannot create a frequency constraint if you created an optimization target that tries to maximize the natural frequencies.
Displacement Constraint The displacement of selected vertices cannot exceed a specified magnitude either in any direction or in a specified direction.
Stress Constraint The maximum stress in a design space cannot exceed a specified value. You can create multiple stress constraints and apply them to one or more design spaces.
Fastener Force Constraint The axial stress and the shear stiffness in a selected bolt cannot exceed a specified value.
Center of Gravity Constraint The center of gravity changes during optimization. You can constrain the center of gravity to its initial location or restrict it to a defined point, line, or plane.
