Fixed 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, for Fixed support, we restrict all the DOF at a point, edge or face.

Analysis Type – This boundary condition are available in only following ANSYS Analysis type
  • Static Structural
  • Transient Structural
  • Harmonic Response
  • Explicit Dynamics
  • Modal
