Defining an ALE adaptive mesh region

You can define regions of the model where you want ALE adaptive meshing and you can specify the frequency and intensity of adaptive meshing for that domain. For more information, see the following sections:

Note:

You can define only one adaptive mesh domain for any particular step.

  1. From the main menu bar, select OtherALE Adaptive Mesh DomainManager.

    Abaqus/CAE displays the ALE Adaptive Mesh Domain Manager showing the steps defined in the model and the adaptive meshing controls associated with each step.

  2. In the ALE Adaptive Mesh Domain Manager, select the step during which you will configure the adaptive meshing, and click Edit.

    Abaqus/CAE displays the ALE adaptive mesh domain editor.

  3. At the top of the editor, choose Use the ALE adaptive mesh domain below.
  4. Click next to the Region field, and use one of the following methods to select the region you want to mesh:

    • Use an existing set to define the region. On the right side of the prompt area, click Sets. Select an existing set from the Region Selection dialog box that appears, and click Continue.

    • Use the mouse to select a region in the viewport. (For more information, see Selecting objects within the current viewport.) Click mouse button 2 to indicate you have finished selecting.

    Abaqus/CAE highlights the selected regions in red in the viewport.

    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 on the right side of the prompt area.

  5. If you want to specify nondefault adaptive mesh controls, toggle on ALE Adaptive mesh controls, and select the name of the adaptive mesh controls to associate with the region.

    If you have not yet created mesh controls, you can click to the right of the ALE Adaptive mesh controls field to define the controls that you want to assign to the adaptive mesh domain. See Specifying controls for ALE adaptive meshing.

  6. Enter the Frequency, in increments, at which Abaqus will mesh the region.
  7. Enter the number of Remeshing sweeps per increment. An increment in this case is each adaptive mesh increment, as defined by the Frequency setting above.
  8. For adaptive meshing in Abaqus/Explicit steps, type the number of Initial remeshing sweeps that Abaqus/Explicit will apply at the beginning of the step.
  9. Click OK to save the settings and to close the ALE adaptive mesh domain editor.

    The ALE Adaptive Mesh Domain Manager displays the adaptive mesh controls associated with the step.

  10. Click Dismiss to close the ALE Adaptive Mesh Domain Manager.
