Creating and Editing Flow Lines

VMoveCAE provides the ability to create flow-lines. At present, two types of flow-lines, streamlines and path-lines are supported. This support is also limited to unsteady flows only. This tutorial describes the procedure for creating streamlines and path-lines.

  1. Start VMoveCAE and Load a CFD file: Start VMoveCAE and load the a CFD file.

  2. Select Velocity in the results list: Select a velocity result. This enables the flow-lines tool in the toolbar.

    Velocity Selected
  3. Click on the “Add Flow Lines” tool: Flow-lines can be created using “Flow Lines” window. To enable this window, click on the “Add Flow Lines” tool. This pops up the “Flow Lines” window.

    Flow Lines Window
  4. Set flow-line parameters and click “Add”: User can provide various flow-line parameters in the “Flow Lines” window. User can select between “Streamlines” and “Path lines” Starting locations needs to be provided by the user for the streamline/path-line. User can either provide a single point, or select a part from the “Geometry and Features” tree. When a part is selected, VMoveCAE uses the centroids of the part's faces as flow-line starting points. Path-lines require addtional inputs such as time-step, number of steps in the animation and injection frequency (Ex. injection frequency of 10 means particles are injected at the starting points every 10 steps).

    Parameters Entered
  5. Set flow-line parameters and click “Add”: After providing the appropriate inputs, click the “Add” button in the “Flow Lines” window. This adds a new flow-line in the “Features” tree in “Geometry and Features” window.

    Flow-line Added
  6. Save CAx and open it in VCollab Professional: Translate and create a CAx file. Open it in Professional or Presenter to visualize the added flow-line. For a better flow-line visualization, user can make the parts transparent.
