Creating Surface Sliders

You can create a surface slider restraint on surface geometries. A surface slider restraints fixes the translational degrees of freedom in the direction normal to the selected surface.

Surface sliders are surface constraint joins that allow points of a surface to slide along a coinciding rigid surface. At each point of the deformable surface, the program generates automatically a constraint that fixes the translation degree of freedom in the direction normal to the surface at that point.

Before you begin: A structural analysis simulation containing a restraint set must be open.

  1. In the Restraints toolbar, click Surface Slider .

    The Surface Slider dialog box appears.

  2. Optional: In the Name box, modify the name of the restraint.

  3. Select the support.

    Symbols representing the surface slider are displayed on the support.

    Tip: You can select several supports in sequence to apply the specification to all supports simultaneously. Any selectable geometry is highlighted when you pass the cursor over it. To know more about the supports you can select, refer to Authorized Supports.

  4. Click OK.

    The surface slider restraint is created, and Surface Slider.1 appears in the specification tree under the active restraint set.
