When working with models in CFD-CADalyzer, especially the more complicated ones, Blanking, Grouping and Selection tools can considerably simplify model setup and visualization. On the top right corner of the Entity List panel, there are 8 tools that are available in all Picking modes (Edges, Surfaces, Parts).

These tools perform the following functions:

Blanking and Unblanking

Blank - Blanks selected entities: To blank front surfaces/parts to gain access to the rest of the model; to check the grid on the inner surfaces/parts of the model. Ctrl-B (after making the selection) is the corresponding keyboard command.

Blank Remaining - Blanks all unselected entities: To blank out everything except one (or a few) part that needs to be worked on. Ctrl-R (after making the selection) is the corresponding keyboard command.

Unblank - Unblanks selected objects: To make visible a surface/part that was just blanked out.

UnBlank All - Unblanks all entities: To make all surfaces/parts in the model visible again

Grouping and Ungrouping

Group - Groups selected entities: To group together surfaces that are to be assigned the same boundary condition (similarly for parts with same VCs); group together surfaces/parts over each of which the grid needs to be locally refined to the same extent.

Ungroup - Ungroups selected group: destroys the grouping and gives back the individual surfaces/parts.

General Selection

Select All - Selects all visible entities. Ctrl-A is the corresponding keyboard command.

Deselect All - Deselects all entities
