*ADAPTIVE MESH REFINEMENT

Activate adaptive mesh refinement in an Eulerian domain.

This option is used to activate adaptive mesh refinement in an Eulerian domain and to specify the refinement criteria in that domain.

Required parameters

ELSET

Set this parameter equal to the name of the element set where adaptive mesh refinement is applied.

Optional parameters

LEVEL

Set this parameter equal to the maximum number of levels of refinement. The default value is 1.

COARSENING

Set COARSENING=YES (default) to specify that refinement can be removed once the refinement criteria are no longer met.

Set COARSENING=NO to specify that refinement cannot be removed even when the refinement criteria are no longer met.

RATIO

Set this parameter equal to the ratio of the maximum increase in the number of elements during mesh refinement compared to the original number of elements in the specified element set. The default value is 8.0.

Data lines to define the criteria used in the mesh refinement

First line

  1. Refinement criteria label (see Defining adaptive mesh refinement in the Eulerian domain).

  2. Value of the refinement criteria if applicable.

  3. Repeat this data line as often as necessary to define multiple criteria for mesh refinement.
