Exporting Mapped Data

Simcenter STAR-CCM+ solution data that has been mapped onto an imported CAE model can be exported from Simcenter STAR-CCM+ so that it can be used in an external CAE package. Data is exported from Simcenter STAR-CCM+ in text files that can be read by the respective CAE package.

The following table shows the export options supported by Simcenter STAR-CCM+:

CAE Package
Field Function NASTRAN Abaqus ANSYS RadTherm
Pressure

Traction





-
Heat Transfer Coefficient and Reference Temperature

Before exporting data, ensure you have mapped the surface, beam or volume data from the Simcenter STAR-CCM+ model to the imported model.

To export mapped data:
  1. Right-click the Imported Models > [Imported CAE model] node of interest and select Export Mapped Data...

In the Export File dialog:
  1. Navigate to the location you want to save the file and enter a file name, or select an existing file. If you activate Append to existing file, the exported data will be added to the end of the selected file.
  2. Use the Export Mode menu at the bottom-right of the dialog to select either the Surface Data or Volume Data export option.

    This selection will affect the options shown in the dialog.

  3. In the Imported Surfaces or Imported Volumes tab (depending on the selected export mode), select the surfaces or volumes for which you wish to export data.
    In the following screenshot, the settings specify that surface data will be exported for the imported surface INNER.

  4. Select the FieldFunctions tab.
  5. From the Export data as menu, select the field data you wish to export.
  6. From the Data to export menu, select the corresponding field function.

    Note that to export heat transfer coefficient data, select the mapped heat transfer coefficient field function in the Data to export menu and the mapped reference temperature field function in the Tref to export menu. To export traction data, select the mapped wall shear stress field function in the Data to export menu and the mapped pressure field function in the Pressure to export menu.

    If you are exporting Temperature data for surfaces, you should select Temperature BC. If you are exporting Temperature data for shell surfaces, you can choose either temperature option.

  7. Ensure the correct units are selected in the Export units menu.
  8. A summary of the selected surfaces/volumes and field functions will be displayed in the box underneath the tabbed panel.
    In the screenshot below, the settings specify that the Mapped Local Heat Transfer Coefficient and Mapped Local Heat Transfer Reference Temperature field functions will be exported as heat transfer coefficient data.

  9. To export the data, click Save.

If no mapped field functions are available for the selected surface or volume, a message will be displayed in the summary box in the Export File dialog. Further information on exporting data to NASTRAN, Abaqus, ANSYS, and RadTherm are provided in a separate section.
