Create Isosurfaces

Displays surfaces along which the parameter is constant.

Procedure

  1. Open the Isosurfaces  dialog:
    • On the ribbon, click Flow Simulation > Results > Insert > Isosurfaces.

    • On the toolbars, click Isosurfaces on the Flow Simulation Results Features toolbar.

    • In the menu, select Tools > Flow Simulation > Results > Insert > Isosurfaces.

    • In the Flow Simulation analysis tree, right-click the Isosurfaces item and select Insert.

  2. Under Parameter, in the Parameter  list, select a parameter for which you want to display isosurfaces.
  3. Under Definition select the way results are displayed:
    • One by One. This mode allows to specify each displayed value of the parameter separately.

    • Number of Levels. This mode allows to specify the range within which the parameter changes.

  4. If the One by One mode is selected, under Value 1 specify a parameter Value  for the isosurface.

    Select Value 2 to create another isosurface and specify the parameter value for the second isosurface. You can create up to sixteen isosurfaces.

  5. If the Number of Levels mode is selected, under Value specify the range within which the parameter changes.

    To see how the parameter changes within the specified range, specify the Number of Levels  (see Number of Levels).

    Then specify the parameter Minimum  and Maximum  values, which are the lowest and highest values to be displayed.

  6. Under Appearance specify the coloring options.
    • In the Color by  list, select the way to color isolines:

      • If you want to display the isolines using a fixed color, select Fixed Color and click Color  button to specify this color.

      • If you want the isolines to be colored in accordance with the distribution of the parameter, select By Parameter.

        • To see how a parameter changes within the specified range, click Adjust Minimum/Maximum and Number of Levels .

          Then specify the parameter Minimum  and Maximum values, which are the lowest and highest values to be displayed.

          To automatically set Minimum or Maximum to the parameter lowest value in the whole computational domain, click Auto Scale to Global Minimum  or Auto Scale to Global Maximum .

          To automatically set Minimum or Maximum to the parameter lowest value in the plot, click Auto Scale to Plot Minimum  or Auto Scale to Plot Maximum .

          Note:

          If the Auto Scale to Plot Minimum/Maximum mode is selected, the plot has its own color bar and the maximum and minimum values are updated accordingly to the displayed plot area when the plot is shown or exported.

          Then specify the Number of Levels .

        • For vector parameters with the separately listed X, Y and Z components you can select a Coordinate System  calculated. By default, the Global Coordinate System is selected.

          You can replace the Global Coordinate System by selecting your coordinate system in the flyout FeatureManager design tree. To create a coordinate system, click Insert > Reference Geometry > Coordinate System.

    • Plot Transparency . Sets the transparency for the plot in the range from 0 (full opacity) to 1 (full transparency).

    • Grid  can be toggled on/off. Grid Step is the distance between adjacent lines of the grid projectedonisosurfaces.The grid displayed on the isosurface helps you see the isosurfaces shape.

  7. Under Options specify general display options for the isosurfaces.
    • Moving display (available if you have selected the Local region(s) (Sliding) option on the Analysis Type tab of the General Settings or Wizard dialog). When checked, the plot moves with the rotating region.

  8. Under Crop Region define the 3D box that crops the isosurfaces plot area (see “Crop Region (Isosurfaces)” for details).
  9. You can immediately show up all changes made in the plot definition on the plot.

    To preview the plot, click the Detailed Preview  button at the top of the dialog.

    Now all changes made in the plot definition immediately show up on the plot.

    Note:

    All changes made in the Preview mode are not saved until you click OK .

  10. Click OK  to create the plot and close the dialog.

    -or-

    Click Keep Visible  before clicking OK  to keep the dialog open and proceed with the plot definition.

Results

The new isosurfaces item appears in the Flow Simulation analysis tree.

To edit definition of the plot, in the Flow Simulation analysis tree, double-click the plot item, or right-click the item and select Edit Definition.
