Creating and Editing Iso-Surfaces

VMoveCAE also provides the ability to create iso-surfaces. This tutorial describes the procedure for creating iso-surfaces.

  1. Start VMoveCAE and Load a CAE file: Start VMoveCAE and load the new_file.rst file provided in the Samples directory.

  2. Select any scalar result or derived type: Iso-Surfaces can be created for scalar results only. For vector, 6-DOF and tensor results, user can create iso-surfaces for their scalar derived types. Selecting on a scalar or a derived type enables the “Add Iso-Surface” tool.

  3. Click on the “Add Iso-Surface” tool: Iso-surfaces can be created using “Iso-Surface” window. To enable this window, click on the “Add Iso-Surface” tool. This pops up the “Iso-Surface” window. The result for which the iso-surface is created is shown as the iso-surface label and its value is displayed in a text area which can be altered as desired.

  4. Add an iso-surface: Let us now enter an iso-surface value say “10” in the text area and click on “Add”. This will create the “Strain Energy = 10” iso-surface as shown in the following diagram.

    First Iso-Surface


  5. Changing iso-surface properties.: Let us now add a second iso-surface at say “Strain Energy = 25” by entering 25 in the text area and pressing Add.

    Added second iso-surface


    Let us now select the iso-surface “Strain Energy = 10”. We can observe that the label and values on the “Iso-Surface” window changes accordingly. This can be repeated by selecting the “Strain Energy = 25” again. Let us now change the properties of “Strain Energy = 25” iso-surface. Now expand the “Stress” tree to display its derived types. Now select “Von Mises”. This will change the iso-surface label to “Stress - Von Mises”. Enter a value of 120 and click apply.

    Changing the second iso-surface

    One can now observe that the iso-surface “Strain Energy = 25” is now changed to “Stress - Von Mises = 120”.

  6. Save CAX: Translate and create a CAX file. Open it in Pro or Presenter to visualize the iso-surface. If the iso-surface is out of bounds and not cutting the geometry then no iso-surface will be created. The next beta version will provide a slider to improve the iso-surface interface and to help the user understand the valid ranges.
