-Intact.Simulation for Grasshopper can restrain surfaces or meshed surfaces to be fixed in all (default) or mixtures of coordinate directions.  Restraints are applied to faces of components participating in the simulation by connecting to the Restraints input on the stress solver component.
+The FixedRestraint block in Intact.Simulation for Grasshopper can restrain surfaces or meshed surfaces to be fixed in all directions.  Restraints are applied to faces of components participating in the simulation by connecting to the Restraints input on the stress solver component.
+If you need a non-homogenous restraint (fixing displacement to a non-zero value along some axis) or a partial restraint (only fixing some axis) please use the [[wiki:sns:intactgh:displacementbc|displacement boundary condition]].

-A restraint has four inputs:
+A restraint has one input:
   * the geometry of the surfaces to be restrained
-  * a Boolean indicating if the surface is fixed in the X direction
-  * a Boolean indicating if the surface is fixed in the Y direction
+A restraint fixes the selected geometry in all directions.
-  * a Boolean indicating if the surface is fixed in the Z direction
-NOTE: Currently, partial fixing of directions is not supported.

+===== Sliding Restraint Using Displacement Boundary Condition Block =====
+Apply sliding boundary condition (along X, Y, and/or Z axes) using the [[wiki:sns:intactgh:displacementbc|Displacement Boundary Condition]] block. Specify no displacement to the directions that allow sliding.
