About this Block
What it does: The Displacement Restraint can apply a restraint over the selected boundary. Displacement Restraint block restrains the selected boundary entities in up to 6 degrees of freedom. The default X, Y, and Z directions are the global reference directions. The X, Y, and Z directions are chosen from a reference frame if a Frame input is provided. The corresponding degree of freedom will be unrestrained if an input is empty. Commons uses:- Boundary condition in an analysis.
- A prescribed displacement is used when the deflection/displacement allowed is known.
- To prescribe a displacement using the Displacement Restraint block, input a displacement value you wish to move the boundary in each degree of freedom.
- Note: The displacement input value will not be divided by the number of nodes/faces in the boundary selected.

The example below shows a brake pedal simulation setup with just two displacement restraint blocks; one is used to restrain all DOFs, and the other allows Uz of -10mm. Download Example: Displacement Restraint
