Extension for Ansys Workbench

How to use it

1. Install and load Ansys Workbench Extension

  • During the CFturbo installation, the Workbench Extension is installed automatically for all available Ansys versions, if this was not deactivated explicitly.
  • The installation is made in the corresponding directory
    c:\Program Files\Ansys Inc\<Version>\Addins\ACT\extensions\.

For manual installation, the following procedure must be used:

  • Download the Extension CFturbo.wbex
  • In Ansys Workbench the file CFturbo.wbex has to be selected via the menu Extensions / Install Extension.
  • Installation is made in the directory
  • The extension is loaded by the Extension Manager, menu Extensions / Manage extensions. Then the extension CFturbo must be activated via the checkbox. In order to load the extension automatically, "Load as Default" must be selected from the right‑click menu.

Additional Prerequisites

To enable the usage of Named Selections for workflows with CFturbo, the following prerequisite needs to be fulfilled:

  • In the Tools menu inside Ansys Workbench, select Options.
  • Click on Geometry Import in the bottom left corner of the dialog and scroll down to the Basic Options area on the right.
  • Check that the Named Selections option is selected and Filtering Prefix is set to NS.

2. How it works

2.1 Create CFturbo subsystem

  • CFturbo is available as a separate subsystem in the Ansys Workbench Toolbox.
  • By double-clicking or drag-and-drop, a CFturbo system with a setup component can be integrated into the project.
  • Double-click the Setup container or choose Edit from the right-click menu to open CFturbo interactively.

2.2 Configure CFturbo Subsystem

  • The parameter and export configuration can be made within CFturbo using PROJECT / Ansys Workbench.
  • All CFturbo settings are saved in the working directory of Ansys Workbench.

2.3 Display in the Ansys Workbench

  • For every exported component, the CFturbo system creates a corresponding component in Ansys Workbench. The exported CFturbo nodes and the corresponding Ansys application are displayed.
  • The parameters created in CFturbo are written into the parameter set within the Ansys Workbench. Parameters can be modified bi-directionally.

2.4 Update options and information

  • CFturbo can export geometry to SpaceClaim in 2 alternative formats: STEP, PARASOLID
  • The CFturbo Workbench extension provides an option to process the geometry in SpaceClaim. This option applies to all SpaceClaim exports from CFturbo and can be set in the Project Schematic properties of the CFturbo setup cell ("Convert *.stp to *.scdoc").
  • The following conversions are made:
    - STEP : The conversion option is optional. If it is active, geometry exports in *.stp format are converted to SpaceClaim's *.scdoc file type, which includes Named Selections of relevant geometry features.
    - PARASOLID : The conversion option has to be used mandatory. Geometry preparation is performed, but currently no Named Selections are available.
  • CFturbo export updates can be performed for the complete CFturbo system by selecting Update in the right-click menu of the CFturbo system header
  • All files created by CFturbo can be viewed in the workbench. See View / Files menu.
  • To view the logfile, see Extensions / View Log File.

2.5 Workflows

  • CFturbo models can be linked to corresponding Ansys Workbench systems.
  • To add a new system with a link to a CFturbo export cell, right-click the appropriate cell in the CFturbo system and select Transfer Data To New... from the context menu.
  • If the conversion of STEP files into the SpaceClaim Document file type was activated, one can use the created Named Selections in other Ansys Systems like Ansys Meshing, CFX-Pre or CFD-Post to reduce the configuration effort and fortify the workflow.

3. Current restrictions

  • When using SpaceClaim, problems may occur under certain circumstances, the solution of which is described in the CFturbo manual.
  • The status of the *.stp to *.scdoc conversion should be set onetime before the initial update of the CFturbo system. If the conversion option is changed later, one needs to reset the cell state of the CFturbo export cells manually.

4. Uninstalling Ansys Workbench Extension

a) after automatic installation

  • Delete the following in the installation directory
    c:\Program Files\Ansys Inc\<Version>\Addins\ACT\extensions\:
    - File CFturbo.wbex
    - Directory CFturbo
    (Administrator rights required, Workbench needs to be closed)

b) after manual installation

  • To uninstall, use the Extension Manager,  Extensions / Manage extensions.
  • Important: To uninstall the extension, it must not have been loaded when the workbench was started. Therefore, the extension must first be deactivated and the workbench must be restarted.
  • Then the extension can be uninstalled via context menu.
