• Using Reference Geometry
  

  You can use a selected reference geometry to apply restraints. The reference can be a plane, axis, edge, or face. Using this option you can prescribe restraints on vertices, edges, faces and beam joints.

• On Flat Face
  

• On Cylindrical Face
  

• On Spherical Faces
  

• Symmetry
  

  You can use symmetry to model a portion of the model instead of the full model. The results on the un-modeled portions are deducted from the modeled portion. When appropriate, taking advantage of symmetry can help you reduce the size of the problem and obtain more accurate results.

• Bearing Fixture PropertyManager
  

  The PropertyManager allows you to simulate the interaction between a shaft and the ground through a bearing. Since the components supporting the shaft are assumed to be much more rigid than the shaft, they can be considered as the ground.The feature is available for static, frequency, linear dynamics, and buckling studies.
