Description

Transforms the coordinate system of a face to a particular coordinate system - rectangular or cylindrical.

Usage

  1. Apply the Constraint displacement to a face first.
  2. There are several ways to invoke the command:
    • Press the FEM ConstraintTransform button.
    • Select the Model → Geometrical analysis features → Local coordinate system option from the menu.
  3. Select rectangular or cylindrical transform. The former can be applied to any face, the latter is available only for the cylindrical faces.
  4. Select a face to which the displacement constraint was previously applied. Press the Add button.
  5. For rectangular transform, specify a rotation about each of the three axes.

Limitations

  • Cylindrical transform can be applied only to cylindrical faces.

Notes

  • This constraint can be used to simulate torsion but only for cylindrical bars or parts containing such bars used to transmit torque.
  • The constraint uses the *TRANSFORM card in CalculiX.
