Frictionless Support

An object have six degree of freedom in space. There are three translational and three rotational Degree of Freedom.

1.       Translation in X (Ux)

2.       Translation in Y (Uy)

3.       Translation in Z (Uz)

4.       Rotation about X (RotX)

5.       Rotation about Y (RotY)

6.       Rotation about Z (RotZ)

We apply support to restrict these DOF. In ANSYS, Frictionless Support provide Support in normal direction to the selected face or edge. The body can not move or rotate or deform in normal direction. But free to move or rotate or rotate in tangential direction.
