Creating a remeshing rule

Remeshing rules enable Abaqus/CAE to adapt your mesh iteratively to meet error indicator targets and sizing criteria that you have specified. For more information, see What are remeshing rules?.

  1. From the main menu bar, select AdaptivityRemeshing RuleCreate.

    Tip: You can also create a remeshing rule using the tool, located with the mesh tools in the Mesh module toolbox. (For more information, see Using the Mesh module toolbox.)

  2. Select the regions to which Abaqus/CAE will apply the remeshing rule, or click Done to select the entire model. If you assign a remeshing rule to a dependent instance, Abaqus/CAE remeshes the original part and each dependent instance of the part inherits the same mesh. The modeling space of the region must be homogeneous. For example, Abaqus/CAE does not allow you to select a region that contains both solids and shells.

    If necessary, you should use the Partition toolset to isolate regions that will generate stress singularities and to exclude those regions from the remeshing rule. For more information, see Singularities.

  3. The Create Remeshing Rule dialog box appears.

  4. If desired, use the Name text field to change the name of the new rule.

  5. If desired, use the Description text field to enter a description of the remeshing rule. You can use the description to help you keep track of the scope and the purpose of your remeshing rules. The Remeshing Rules Manager displays the name and the description of a remeshing rule.

  6. Click the Step and Indicator tab to select the following:

    • The step to which the remeshing rule will be applied.

    • The error indicator output variables that Abaqus/CAE will write to the output database, and the frequency at which they will be written.

    For more information, see Selecting the step and error indicator output variables for the remeshing rule.

  7. Click the Sizing Method tab to select the following:

    • The method that Abaqus/CAE will use to calculate the size of the elements during the remeshing process.

    • Whether to use automatic reduction of error indicator targets for the adaptive remeshing process or whether to specify the error indicator targets.

    For more information, see Choosing the remeshing rule sizing method.

  8. Click the Constraints tab to select constraints on the element size during the remeshing process. For more information, see Choosing remeshing rule constraints.

  9. Click OK to create the remeshing rule and to close the Create Remeshing Rule dialog box.
