Restrain XY

The Restrain XY option is used to apply pinned boundary conditions.

The nodes will not be free to move in the X or Y directions, and will maintain zero displacement throughout the analysis.

Nodes restrained in the X and Y directions are indicated by a triangular "pin" symbol, when Restraints are displayed, as configured in the Display Options dialog.

See the Applying Restraints topic for information about applying restraints.

Tips

By default, the entire External boundary is given a "pinned" boundary condition when the External boundary is initially created and the mesh is generated. It is not necessary for the user to apply the Restrain XY option on the External boundary, unless you wish to change previously applied Restrain X, Restrain Y or Free boundary conditions.
