Creating Static Scenarios

You can create a static scenario that is a basic analysis where the stiffness forces are mainly considered and the effect of inertia forces and damping forces are ignored. For example, if the loading is constant over a relatively long period of time, static solution scenario is sufficient.

Inserting a static scenario allows you to create environmental specifications, and to implicitly require a static solution procedure for the computation of the system response to applied static loads under given restraints.

A static scenario must reference one and only one restraint set, and one and only one load set. You can also reference additional masses.

Before you begin: A structural analysis simulation referencing a finite element model and containing an activated Scenario object must be open.

  1. In the Scenarios toolbar, click Static Scenario .

    The Static Scenario dialog box appears. By default, a new and empty restraint set (New Restraints), a new and empty load set (New Loads), and a new and empty mass set (New Masses) are referenced in the Excitations tab. At this stage, the three sets do not exist yet. They are created at the same time as the scenario.

  2. Optional: In the Name box, modify the scenario name.

  3. If the product contains several finite element model representations, select the finite element model representation you want to use in the FE Model box. If the product contains only one finite element model representation, this representation is selected automatically in the FE Model box.

  4. Optional: In the Excitations tab, change the excitation sets that you want to use to define the scenario. To reference an existing set:

    1. Select the desired tab.
    2. In the Available list, select an existing set.
    3. Click .

      The selected set appears in the Referenced list.

    Important: In a static scenario, a restraint set and a load set are mandatory. A mass set is optional.

  5. Optional: To define a static scenario without additional masses:

    1. Select the Masses tab.
    2. In the Referenced list, select the referenced mass set.
    3. Click .

  6. Optional: By default, the Gauss method is used for static scenario computation. To modify the scenario parameters, click the Parameters tab, and modify the scenario parameters.


    • The Gradient method is a solving iterative method which is memory saving but not CPU time saving. It is recommended for computing huge models without contact. If you selected Gradient, you have to specify:
      • Maximum iteration number to set the maximum number of iteration. If you enter 0 as maximum iteration number, the necessary number of iteration will be automatically calculated.
      • Accuracy to set the precision of convergence (by default: 10-8).
    • Self balancing loads: lets you choose whether you wish to apply self-balancing to loads. If selected, this option adds automatically inertia forces to counter balance external loads. The global loading equals null. This kind of loading is used when modeling free bodies submitted to constant external forces (for example: a rocket during lift-off). This option is usually combined with iso-static restraint. In this case, reaction forces are null, which simulates a free body.

  7. Click OK.

    The scenario is created and appears in the specification tree with the selected excitation sets.

You can find below an example of what you obtain in the specification tree if you keep all the default options:

At any time, you can modify the content of the scenario.
