For connectors and domains only, selecting the Database Associativity function causes grid points to be rendered in the Display window
according to whether those points are database constrained or free.
Tip: For most users maintaining the true shape of their underlying geometry is critical to a proper CAE solution. Prior to exporting to
your solver, always verify the database constraint of your wall surface grids using the Database Associativity function. You may wish to maintain
these wall domains in a particular or set of layers for easy selection.
At the top of the Options frame (shown below), you will find the Number of Database Entities associated with the currently selected grid
entities. The toggle buttons On and Off indicate whether or not to render grid points that are on or off database entities
respectively. Points that are projected to a database entity (on) are rendered in green while points that are not projected to a database entity (off) are
rendered in red. The number and total percent of grid points that are on or off a database entity can be seen in the Count and Percent
Use the Database Associativity function to visually determine which grid points are database constrained and the database entities they are
Tip: A point that is off the target database entity can be corrected using the Tweak command.
The Database Sources frame provides controls to color projected grid points and relevant projection information on a per database entity
basis. The On column indicates whether or not to render the grid points projected to specific database entities.
The Database column indicates the names of the different database entities with grid points projected to them; database entities without grid points
projected to them will not be listed in this table. The Count and Percent columns indicate the number and total percent of grid points
projected to specific database entities respectively. Finally, the self-explanatory All On and All Off commands operate on the entire list
of database entities.
Keep in mind that Fidelity Pointwise considers a point to be off a database if the point does not have an explicit reference to a database entity and parametric
coordinates. A point flagged as off may actually be within the same point tolerance of the database.
Cursor over a point that is constrained to a database entity, as shown below, the UV coordinates and the name of the associated database entity will be
displayed in the Probe area.
If a grid point is database constrained, the corresponding UV values will be displayed in the probe area in
the Status Bar
If you wish to examine other entities of the same type as the current selection, expand the Selection frame (shown at the top) and click
on Begin. Press End when the new selection is completed. The current selection can be highlighted in the Display window by checking
the Highlight Selection option.
