Definition steps

warning.pngWhile support definition, keep in mind not to create unstable situation! For example in 3D modules, model a hinged support under a wall with hinged line support added to a wall at its rigid edge or with rigid line support added to a wall at its hinged wall. In case of unstable situation the program sends a warning message during calculation.

  1. If needed (and available in the current FEM-Design module), set a proper position for the working plane.
  2. Start the required support command from 1585145535323-432.png  tabmenu and choose 1585145541678-956.png  Define.
  3. In case of single Support, choose the displacement type you would like to be define:
    • 1585145547383-422.png  Motion
    • 1585145553532-957.png  Rotation
  4. Set the support properties as mentioned before in the applied support’s Default settings dialog. See the settings possibilities and options at Properties (Non-Linear Behaviors).
    In the settings dialog of a curved line support, the support direction has to set fixed or variable along the support’s reference line.

  5. Define the required support component direction for the single Support or set the reference system for the Support group.
  6. Choose a geometry definition method for the support’s reference point/line/region.
  7. Define the support in the model view based on the chosen geometry method.

Optional steps:

  1. Modify the geometry with the Edit menu commands valid for line/region elements.
  2. Modify the support properties with the 1585145568759-165.png  Properties tool of the support’s tool palette.
  3. Set the display settings of supports at Settings > All > Display > Support.1585145602181-743.png
    warning.pngLabel” represents the supports’ ID number generated by analysis/design calculation or by clicking Refresh numbering (Tools menu).

    Rotation support is displayed with symbol strongly different from motion representation.

    light.pngSupport groups can also be separated from the single Supports by displaying their Local system.

  4. The supports are stored on “Supports” Object layers. At layer settings, the default color of the single Supports and pen width of all support types can be set. The color and the symbol line type (e.g. dotted) of selected supports can be modified by Edit > Properties > Change appearance.
