## 8.1. Vista RTD Workflows

There are two main ways to use Vista RTD:

- Vista RTD can be used in an iterative fashion to create a 1D design as follows:

  1. With ANSYS Workbench running, create a new Vista RTD system (available in the Component Systems toolbox).

     (Double-click the Vista RTD system or drag it onto the Project Schematic view.)

  2. Either Edit the Blade Design cell (of the new Vista RTD system) or show that cell's properties.

     (Right-click the Blade Design cell and select either Edit or Properties from the shortcut menu.)

     Editing the cell causes the Vista Radial Turbine Design dialog box to appear.

     The cell properties can be used as an alternative to the dialog box. One advantage of using cell properties is that you can make use of Workbench input parameters to specify the values of input settings.

  3. Specify the required input settings:

     - Information about the operating conditions such as mass flow rate, expansion ratio, and rotational speed

     - The fluid properties

     - Geometric constraints such as the mean vane thickness at the throat

     - Some aerodynamic and geometric settings (for example, the number of vanes) that are open to change during this 1D design procedure.

     See Data Review and Edit for details on the input settings.

  4. Compute a turbine design by clicking Calculate.

  5. Assess the results.

     See Viewing the Results for descriptions of the results.

  6. Continue to revise the input data and refresh (regenerate) the results until you obtain a satisfactory 1D design.

- Vista RTD can be used to model an existing turbine. This use of Vista RTD is described in Using Vista RTD to Model an Existing Turbine.
