Move or Delete Existing Points
Select this option on the Settings tab if you want AutoGEM to move or delete existing points as required.
AutoGEM sometimes cannot create a full set of elements on a surface or volume having complex features. If you select Move or Delete Existing Points, AutoGEM is more likely to fully cover the surface or volume with elements. In general, you should select Move or Delete Existing Points.
AutoGEM moves or deletes a point only if the point meets the following conditions:
The point is associated with a single curve, a single surface, or both a curve and surface associated with each other.
The point is not associated with model entities such as loads, measures, or material properties.
The point is not a user-created datum point.
