SYMPTOM:
When modifications (e.g. name changes, location changes, creation/deletion) are made to Named Selections in DesignModeler, some changes are not reflected in CFX-Mesh after perrforming a Geometry Update action.

PROBLEM:
This happens because there is no internal identifier associated with a Named Selection other then the user specified name. Hence when it is renamed, for example, the association between the Named Selection and the Region in CFX-Mesh is lost.

The following behaviour should also be noted:

If you modify the location of an existing Named Selection in DesignModeler, then when you update the geometry in CFX-Mesh, this modification will be applied to the equivalent Composite 2D Region in CFX-Mesh as long as the new location does not overlap with the location of any existing Composite 2D Regions in CFX-Mesh (including other regions generated from Named Selections).

If you delete a Named Selection in DesignModeler then when you update the geometry in CFX-Mesh the equivalent Composite 2D Region is not deleted. You must delete it manually if you no longer want this region in CFX-Mesh.

If you rename a Named Selection in DesignModeler, then when you update the geometry in CFX-Mesh, the Named Selections will not be re-imported. You must either rename or delete the equivalent Composite 2D Region in CFX-Mesh before updating the geometry. This is because CFX-Mesh effectively sees the renamed Named Selection as a new Named Selection, and then finds that its location overlaps with the existing Composite 2D Region which has the original name of the Named Selection.


WORKAROUND:
There is no workaround.

FIXED IN:
ANSYS CFX Release 11.0.
