Editing the region to which a prescribed condition is applied

You can edit the region to which a prescribed condition is applied in the step in which the load, boundary condition, or predefined field was created. You cannot edit the region if the definition of the prescribed condition refers to subregions within the original region (a material assignment predefined field, for example).

Note: Gravity loads can be applied to regions in your model, but they cannot be applied to individual point masses in Abaqus/CAE.

Using the Load module

  1. From the Load, BC, or Predefined Field menu in the main menu bar, select Manager to display the Load Manager, Boundary Condition Manager, or Predefined Field Manager.

  2. Click the cell located in the row of the prescribed condition that you want to modify and in the column of the step of interest, and click Edit. Alternatively, you can just double-click the cell.

    Tip: You can also initiate this procedure by clicking the step in which the prescribed condition was created in the Step list located in the context bar. From the Load, BC, or Predefined Field menu in the main menu bar, select Editprescribed condition. For example, to edit a load you would select LoadEditload of your choice.

    An editor appears.

  3. In the top part of the editor, click to edit the region selection.

  4. Edit the region using one of the following methods:

    • Select and unselect objects in the viewport. When you have finished editing the region, click mouse button 2. (For more information, see Selecting objects within the viewport.)

      Tip: You can limit the types of objects that you can select in the viewport by specifying filtering options in the Selection toolbar. See Using the selection options, for more information.

    • To select from a list of existing sets or surfaces, do the following:

      1. Click Sets or Surfaces on the right side of the prompt area. (The name of the button depends on the type of object you are editing. For example, if you are editing a pressure load, a Surfaces button appears.)

        Abaqus/CAE displays the Region Selection dialog box containing a list of available sets or surfaces.

      2. Select the set or surface of interest and click Continue.

    Note:

    The default selection method is based on the selection method you most recently employed. To revert to the other method, click Select in Viewport or Sets or Surfaces on the right side of the prompt area.

  5. In the editor, finish editing the prescribed condition definition as desired and then click OK.

    The symbols representing the prescribed condition in the viewport change to appear on the newly edited region.
