Part 1: Exporting Superelement

Import Geometry

  1. Open a new SimSolid session.
  2. Click Import from file .
  3. In the Open geometry files dialog, choose Superelement_export.x_t.
  4. Click Open.
    The assembly will load in the modeling window.

Create Connections

  1. In the Automatic connections dialog, accept the default values for Gap and Penetration tolerances.
  2. Set Connection resolution level to Increased.
  3. Click OK.
    Note:
    • SimSolid creates connections even in areas with overlapping geometry.
    • SimSolid automatically identifies bolts, nuts and washers.
    • Sliding contact is applied automatically in bolt shanks, bonded is applied otherwise.

Assign Material

  1. On the Project Tree, click on the Assembly workbench.
  2. On the Assembly workbench, click Apply materials.
  3. Select Steel from the Generic materials list.
  4. Click Apply to all parts.
  5. Click Close.
In the Assembly workbench of the Project Tree, material properties are identified for each part.

Create Structural Superelement Export Analysis

On the main window toolbar, click Structural Analysis > Structural Superelement Export.
The new analysis appears in the Project Tree under Design study 1 and the Analysis Workbench opens.

Create Force Load

  1. In the Analysis Workbench, click Force/Displacement.
  2. In the dialog, ensure the Faces radio button is selected.
  3. In the modeling window, select the highlighted face as shown in the below figure.
    Figure 1.


  4. Specify a Z direction force of -1500 N.
  5. Click OK.
The new force, Force/Displacement 1, appears in the Project Tree. Vectors representing the load are shown on the model.

Import Superelement Interface Points

  1. On the Analysis Workbench click Interface points.
  2. Click Import from .csv.
  3. Select Interface points.csv from the File Explorer.
    Interface points coinciding at the same coordinate points or with same ID will show warnings.
  4. Optional: Change the coordinate units.
    By default, SimSolid accounts the units from the imported geometry.
  5. Click OK.
Point set 1 will be mapped to the respective location of the model.
Figure 2.


Edit Solution Settings

  1. In the Analysis branch of the Project Tree, double-click on Solution settings.
  2. In the Solution settings dialog, for Adaptation select Global+Local in the drop-down menu.
  3. Click OK.

Run Analysis

  1. On the Project Tree, open the Analysis Workbench.
  2. Click Solve.

Export Superelements

After solving the structural superelement export analysis, Export is enabled in the Analysis Workbench.

  1. Click Export to create DMIG file.
  2. In the dialog, select appropriate units for Coordinates as [mm], Stiffness matrix as [N/mm], and Load vectors as [N].
  3. Click OK.
  4. Choose desired directory to save the DMIG file in File Explorer.
  5. Click Save.
DMIG file is created.
