Visualizing the Normal Modes

In Simcenter STAR-CCM+, you can visualize the normal modes solution using a Normal Modes View. The primary use of the Normal Modes View is to apply a normal modes representation to scenes or reports. You can also use the normal modes representation to add annotations to plots.

Each normal mode solution view represents a single eigenmode and its associated eigenvalue or natural frequency. For more information, see Normal Modes.
To create a normal modes solution view:
  1. Right-click the Solvers > Solid Stress Normal Modes node and select New Normal Modes View.
  2. Select the Solution Views > [Normal Modes View] node and set the Result Type.
  3. Select the [Normal Modes View] > Eigen Mode node and set the Mode.
    For more information, see Normal Modes View Reference.
  4. Create the appropriate visualization tool:
    • Scalar or Vector Scene:
      1. Create a Scalar or Vector scene.

      2. Select the [Scene 1] > Parts node and set Parts as appropriate to display the results.

        You can only visualize the normal modes representation when using the following parts as inputs:
        Part Types Derived Part Types
        • Part Surfaces
        • Regions and Boundaries
        • Vector Warps
      3. Select the [Scene 1] > [Scalar 1] node and set the Representation to Normal Modes View.
      4. Select the [Scalar 1] > [Scalar Field] node and set Function to Modal Displacement.
        The Modal Displacement is currently the only physical result (in addition to the standard metric field functions) available for the normal modes view.

    • Plot:
      1. Create a plot.
      2. Select the Plots > [Plot] > Annotations node and select Normal Modes View.
      3. Select the Annotations > Normal Modes View node and set the appropriate properties.

    • Report:
      1. Create a report.
      2. Select the Reports > [Report] node and set the following properties:
        Property Value
        Field Function Modal Displacement
        Representation Normal Modes View
      3. Run the report.
