Creating Forces

You can create the equivalent of the line force density, surface force density and body force by giving only as input a force in Newton (N in SI) and not a force density (N/m in SI for a line force density, N/m2 in SI for a surface force density and N/m3 for body force).


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

  1. In the Loads toolbar, click Force .

    The Force dialog box appears.

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

  3. Select the geometrical support.

    Tip: Multi-selection is available and must be homogeneous. For example, you cannot select an edge and a face.

    Symbols representing the force are displayed on the selected support to visualize the force density field.

  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 vector.

    The norm is computed and displayed automatically in the Norm box. 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.The visualized symbols orientation is also updated to reflect the modification.

  7. Click OK.

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