Creating a Speos system in Ansys Workbench

This page shows the main steps to create a Speos system in Ansys Workbench. The Speos system in Ansys Workbench allows you to create a link between the two software. This link/bridge allows the software to exchange input and output data.

Note: If you need more information on Ansys Workbench functioning and behavior, refer to Ansys Workbench User's Guide.
Note: As a project cannot mix *.scdoc data and *.scdocx data, a Workbench project created with *.scdoc data should be recreated after the *.scdoc file conversion to *.scdocx file

For more information, refer to SCDOC File Import.

To create a Speos system in Ansys Workbench:

Prerequisites: The assembly, all parts used in the assembly, and the Speos input files folder must be located at the same directory level. Plus, all file used by the assembly and parts must be in this same Speos input files folder.
  1. From Windows Start Menu, launch Workbench with Speos.
    CAUTION: If you launch Workbench (not Workbench with Speos), the Speos environment will not be loaded when you open a SpaceClaim session from the geometry system or cell.
  2. Before working, make sure Workbench with Speos runs in foreground, and the Geometry Editor is set to SpaceClaim Direct Modeler:
    1. Select the Tools tab and click Options.
    2. Select the Solution Process section.
    3. In the Default Update Option drop-down list, if not defined, select Run in Foreground.
    4. Now, select the Geometry Import section.
    5. In the Preferred Geometry Editor drop-down list, if not defined, select SpaceClaim Direct Modeler.
    6. Click OK.
  3. If Speos extension is not displayed in the Toolbox, click Extensions> Manage Extensions...
  4. From the list, select Speos and click Close to import the extension in Workbench.
  5. Drag and drop Speos extension from the Toolbox to the Project Schematic pane to create a standalone project.
    Note: Project dependencies are not preserved when duplicating a Speos block.
  6. If you want to modify the solver to compute the simulation:
    1. In the Speos system, select the Simulation Task cell.
    2. In the Properties panel of the Simulation Task, select the Solver to use between Local (CPU) and GPU
  7. To import the Speos project, right-click Geometry > Import Geometry.
    You can select a previously used design (*.scdoc file) or browse to a specific location to retrieve a project.

    Your geometry and project is imported in Ansys Workbench.
  8. If you want to import a geometry parameter (like a dimension parameter), double-click the Geometry cell to open SpaceClaim.
    1. Modify a parameter on a geometry.
      SpaceClaim proposes you to add the parameter in Ansys Workbench.

    2. Click Add as parameter .
      The geometry parameters is linked and imported in Ansys Workbench.

  9. Double-click Speos Simulation Task to open Speos.
  10. In Speos, define the Speos input parameters to import in Ansys Workbench:
    1. From Speos tree, select a feature (a source for example).
    2. Click the Workbench tab and click Publish Parameters .
    3. From the list, select the Speos parameters to be imported (for a source for example, its flux or total angle).
      Note: Publish Parameters are not compatible with the control points positions (%) of the Light Guide feature.
  11. In Speos, define the Speos output parameters to import in Ansys Workbench:
    1. If not already done, create a simulation and Compute it.
    2. Open the result and define Measures.
    3. Select File > Export template.
    4. In Speos, use the template as XML template in the sensor that generated the result.
      This will define the measures as output parameters.
    5. Save the current project.

      All output data/parameters (measure performed on the simulation results) are automatically imported in Ansys Workbench.

      Note: Once the Publish Parameters are defined, you can close Speos or leave it open and running in the background.
  12. In Ansys Workbench, right-click Simulation Task and click Generate Parameters to import Speos input parameters.
    The input parameters are imported into Ansys Workbench. The loop is created between the two software.

The project is created, you can now interact and adjust parameters directly from Workbench to observe result variation.

Tip: If you need to refresh or modify input data, repeat the procedure from step 6. Modify input publish parameters and regenerate the import.
