You use this boundary condition to prevent one or more flat or curved faces from moving or deforming in the normal direction. The normal direction is relative to the selected geometry face. No portion of the surface body can move, rotate, or deform normal to the face.
For tangential directions, the surface body is free to move, rotate, and deform tangential to the face.
For a flat surface body, the frictionless support is equivalent to a symmetry condition.
A Frictionless Support is available for the following analysis types:
The following section outlines the common boundary condition characteristics that include application requirements of the boundary condition, support limitations, as well as loading definitions and values.
