32.5.8 Adapt/Controls...

The Adapt/Controls... menu item opens the Grid Adaption Controls panel.



Grid Adaption Controls Panel


The Grid Adaption Controls panel allows you to set limits on the minimum cell size, the minimum and maximum number of cells, and the cell types that can be adapted. In addition, it allows you to vary the volume weighting of the gradient adaption function. See Section  26.12 for details about the items below.

Controls

Type   contains check buttons that control the type of adaption that is performed. See Section  26.2.3 for information about choosing the adaption method.
Hanging   enables hanging node adaption (the default).

Conformal   enables conformal adaption.

Options   contains check buttons that control the manner in which the grid can be adapted.
Refine   toggles grid adaption by adding points.

Coarsen   toggles grid adaption by removing points.

Zones   contains a list of cell zones from which you can select the zones in which to perform adaption (or marking). By default, all cell zones are selected.

Min Cell Volume   restricts the size of the cell that is considered for refinement. Even if the cell is marked for refinement, it will not be refined if its cell volume is less than this threshold value.

Min # of Cells   specifies the minimum number of cells required in the grid.

Max # of Cells   limits the total number of cells allowed in the grid. A value of zero places no limits on the number of cells.

Max Level of Refine   specifies the maximum level of refinement for the cells.

Volume Weight   controls the volume weighting in the gradient adaption function. Valid values are between 0 and 1: 0 for no volume weighting and 1 for full volume weighting.

Node Removal Flags   contains check buttons that control the node removal permissions associated with the conformal coarsening process. These items will appear only for 2D problems when Conformal is the selected adaption Type and Coarsen is activated.

Boundary - Original   toggles the permission to remove original nodes on boundary zones.

Internal - Original   toggles the permission to remove original nodes on interior zones.

Periodic - Original   toggles the permission to remove original nodes on periodic zones.

Boundary - Refined   toggles the permission to remove nodes generated by refinement on boundary zones.

Internal - Refined   toggles the permission to remove nodes generated by refinement on interior zones.

Periodic - Refined   toggles the permission to remove nodes generated by refinement on periodic zones.
