Generating a Mesh Simulation Model

You can generate a mesh simulation model for a building structure.

  1. Before you begin:
    1. Ensure that you have a valid license to use Structural Scenario Creation app.
    2. Create a structural grid, which can be either a Building Grid or a Reference Plane Grid.
    3. Add catalog columns, beams, braces, and beam pattern.

      Important: Use the columns, beams, braces, and beam patterns that you select from one of the catalogs or use the following profile sketches.
      • Rectangle
      • Round
      • I, T, or L shaped
      Mesh generation in the app supports structural elements based on sketches for hollow and solid structural elements and structural elements of any size.

      Structural Scenario Creation app only supports the analysis of steel simulation models; it does not support the analysis of cast structural elements.

  2. From the Steel section of the action bar, click Generate Simulation Model .
  3. In the Generate Simulation Model dialog box, from Include, select a member.
    OptionDescription
    Include linear members Exports all linear members in the model, such as beams, columns, and braces.
    Include slabs Exports all building slabs in the model.
    Include structural plates Exports all the structural plates in the model.
    Include structural walls Exports all the structural walls in the model
  4. In the Mesh Size 1D box, specify the global size of the 1D mesh.
  5. In the the Mesh Size 2D box, specify the global size of the 2D mesh.

    You can change the mesh sizes in Structural Scenario Creation app while doing the analyses.

  6. Select the Automatic mesh capture check box to specify the external meshes needed to be captured.

    Note: In the Tolerance box, specify the maximum distance for mesh capture.

  7. Select the Create connections automatically check box to create kinematic coupling between the nodes that are within the specified tolerance but are not coincident.

    Note: In the Tolerance box, specify the maximum distance between the nodes to be connected using a coupling.

  8. Click OK.
    A new tab opens with the mesh simulation model in SIMULIA Structural Scenario Creation, where you can perform the simulation analyses such as Buckle-Step Analysis. During the mesh generation, the slabs in the mass are converted to elastic 2D plates, so that you can perform analyses on the slabs as well as the steel structural members.
    Note: The wall needs to be marked as a structural wall before generating a simulation model for it.
