Create Surface Goals

Allows you to specify surface goals for your project.

Procedure

  1. Open the Surface Goals  dialog:

    • On the ribbon, click Flow Simulation > Insert > Goals > Surface Goals.

    • On the toolbars, click Surface Goals on the Flow Simulation Features toolbar.

    • In the menu, select Tools > Flow Simulation > Insert > Surface Goals.

    • In the Flow Simulation Analysis tree, right-click the Goals item and select Insert Surface Goals.

  2. Under Selection, select faces on which you intend to specify the surface goals in the graphics area (see “Selection List” for details).

    The selected faces appear in the Faces to Apply the Surface Goal  list.

    You can also select components in the flyout FeatureManager design tree.

    Tip

    To quickly select faces on which you have specified a boundary condition, fan or surface source, select the corresponding feature in the Flow Simulation Analysis tree. All faces belonging to the feature will be automatically selected.

    • If you have selected several faces and intend to specify several individual goals, one for each face, rather than to treat the selected faces on the whole as one surface, select the Create goal for each surface check box.

  3. Under Parameters, select parameters of interest in the Parameter table.

    • For non-integral parameters (e.g. “Static Pressure”, or “Total Pressure”, etc.) you can also select which parameter values, namely, minimum (Min), average (Av), maximum (Max) or bulk average (Bulk av.) will be used as surface goals.

      All values are calculated on the selected faces.

    • For the components of vector parameters (“Force X”, “Force Y”, “Force Z”, etc.), select the Coordinate System  in which these goals are calculated.

      By default, the Global Coordinate System is selected.

      Tip

      You can replace the default coordinate system by selecting your coordinate system in the flyout FeatureManager design tree.

      To create a coordinate system, click Insert > Reference Geometry > Coordinate System.

    Select the Use for Conv. (Use for Convergence Control) check box if you want the goal’s convergence to be included as a condition of finishing the calculation. If you clear this check box, the goal’s convergence is used for information only so the calculation may be stopped before the goal is converged. See “Finishing the Calculation” for details.

  4. In the Name Template box you can specify a template for names of goals that will be created for selected parameters.

    The default template is an abbreviated name of goal’s type (“SG” for Surface Goals) followed by <Parameter> and <Number>, where <Parameter> is the goal parameter and <Number> is a sequential number of the goal. When goals are created, <Parameter> is replaced by the goal parameter’s name (e.g. “Av Static Pressure”) and <Number> is replaced by a sequential number of the goal (for example, if the goal named “SG Av Static Pressure 1” already exists, the new goal will be named “SG Av Static Pressure 2” and so on). You can also add words “Inlet” or “Outlet” to the template by clicking the corresponding button. You can combine these standard elements in any order and add any appropriate characters to the template.

    To add a new standard element to the template, click the Inlet , Outlet , Parameter  or Number  button.

  5. Click OK .

    -or-

    Click Keep Visible  before clicking OK  to keep the dialog open and define more surface goals.

Results

The new Surface Goal items (SG) appear in the Flow Simulation Analysis tree.

To edit the definition of a Surface Goal, in the Flow Simulation Analysis tree, double-click the Surface Goal item, or right-click the item and select Edit Definition.
