Adding Grid Points to a Connector Based on Surface Curvature
Adding grid points to the connectors on an unstructured domain is generally needed when the underlying database surface is highly curved. Begin with at least one of these connectors that does not adequately follow the curved surface upon which it has been created.
Note that the numbers in the following steps apply to the example database; you will need to find out what dimensions best work for your geometry.
With a connector average spacing of 1.0 set in the Defaults tab, the domain above was created automatically by selecting the database surface and clicking on Domains on Database Entities on the toolbar. However, the resulting domain and connectors created by only using the connector spacing default does not follow the surface curvature very well.
To see how adding grid points to the connectors can improve how closely the domain and connectors conform to the curved surface, follow these steps that make use of a Maximum Angle setting for the connectors.
The domain looks much better and you can see the areas in particular that benefited from the Maximum Angle setting.
To see how adding grid points by setting the Maximum Deviation can improve the connectors' curvature, follow these steps.
You are now out of the Grid, Dimension task panel.
You now have connectors with the original equal spacing dimensions.
Notice that the settings from the previous steps have not changed even though you exited from the task panel.
Click on Apply if you would like to accept the change, and then click on OK to exit the Grid, Dimension menu.
The domain has still improved from the original domain created with only the connector spacing set. But notice the areas where the domain has changed in a different way by having the Maximum Deviation setting versus before when the Maximum Angle was set.
Whether you use Max. Angle or Max. Deviation to add grid points depends on the database surface. As a suggestion, test the use of both settings at different times to see what works for every unique surface.
