Creating Distributed Forces

You can create a distributed force applied to a virtual part or to a geometry selection. Distributed forces are force systems statically equivalent to a given pure force resultant at a given point, distributed on a virtual part or on a geometric selection.

Units are force units (typically N in SI).


Before you begin: A structural analysis simulation containing a load set must be open.

  1. In the Loads toolbar, click Distributed Force .

    The Distributed Force dialog box appears.

  2. Optional: In the Name box, modifiy the name of the load.

  3. Select the support to which the resultant force vector is applied at the predefined point.

    A support can be:

    • One or several geometries
    • One or several groups
    • One virtual part.

  4. Optional: By default, the vector components are defined relative to the fixed global axis system (fixed global rectangular coordinate system). To choose a different axis system, select User in the Type list, and select a user axis system in the specification tree.

    The name of the user axis system is displayed automatically in the Current axis box, and the components of the resultant force are defined relative to the specified rectangular axis system.

  5. Optional: Select the Display locally check box to display the selected axis system locally on the geometry.

  6. Enter values for the X, Y, and Z components of the resultant force vector to specify the three components for the direction of the resultant force.

    The norm is computed and displayed automatically. Upon modification of any of these four values, the resultant force vector components and magnitude are updated based on the last data entry. The resultant force vector remains constant independently of the geometry selection.

    Symbols appear on the selected support to reflect the force orientation.

  7. Optional: Select a handler point.

    • For a geometry or group support, you can select a point.
    • For a virtual part support, you can select the handler point of the virtual part.

  8. Click OK.

    The distributed force is created, and Distributed Force.1 appears in the specification tree both under the excitation library and under the current scenario.
