Constraints behavior in Fusion Simulation

Constraints, in Fusion Simulation, are applied to a model to prevent it from moving in response to applied loads. Loads and constraints often replace parts of the model that we're not concerned with and don't need to model. For example, you may want to know if your shelf can withstand the weight of objects. You can use a constraint to represent the wall that it is attached to. Constraints define where and how the model is fixed.

Note: Constraints in a simulation do not connect two parts together. All loads go through the constraints and into the ground instead of being transferred to the next part. Be sure to define contact between parts, either bonded or separation.

Constraint types and the studies that support them

Study type	Structural Constraint	Connector Constraint	Prescribed Translation/Rotation Constraint
Static stress
Nonlinear static stress
Structural buckling
Modal frequencies
Quasi-static Event simulation
Dynamic Event simulation
Thermal stress
Shape optmization

You can modify the size of constraint markers that are left on the faces after a constraint is applied, in the Preferences dialog. The size can be entered as a percentage of the default so that 200% is twice the default size. The dialogs to change the size are under the General > Simulation section of the Preferences dialog.

Note:

To find information about constraints types available in the Generative Design workspace, see Apply constraints.
