Defining Imported Forces

You can use an imported force to apply time-modulated forces and moments at one or more points in the model. The force and moment data must be stored in an engineering document in the 3DEXPERIENCE platform database.

Each load application point can be a model vertex or a node in the meshed model.

You can use frequency domain data instead of time domain data if the Imported Force feature is created in a harmonic response or modal dynamic step.

  1. From the Loads section of the action bar, click Imported Force .
  2. Optional: Enter a descriptive Name.
  3. Select the geometry supports in the model.

    An imported force can be applied at one or more points. Each point you select must have its own set of force and moment data available in the engineering document file. See About Imported Forces.

  4. Select the File that contains your force and moment data. Click to search for theengineering document (file) in the 3DEXPERIENCE platform database.

    Changes in the referenced engineering document will be taken into account every time the simulation is run again.

  5. Optional: Click to view the data file in a text editor.
  6. Enter the Start column no. for the force and moment data of the first geometry support.
  7. Select one of the following as the Axis system definition:
    OptionDescription
    Global Aligns the local feature triad with the global coordinate system.
    Local Aligns the local feature triad with a selected axis system in the model. If you select this axis system, you must also specify whether the axis system is Cartesian or Cylindrical.
    Specify Orients the local feature triad directly. Right-click the feature triad glyph on the model, and select an orientation tool.
    ImplicitAligns the axis system to the transformed axis system applied on the support.
  8. Click OK.
