The Advanced group of global mesh controls appears in the Details View when the Mesh object is selected in the Tree Outline. The Meshing application automatically removes loops according to the criteria you specify for the loop removal options in this group. Prior to meshing, you can use the Show Removable Loops feature to preview the loops that will be removed according to the current settings.
The loop removal feature is supported for the following mesh methods:
Surface Meshing:
Note:
The loop removal controls are passed to the MultiZone Quad/Tri method as described in MultiZone Quad/Tri Method Control.
If you are meshing with loop removal on (using the Quad Dominant or MultiZone Quad/Tri method), making changes to a loop after meshing (such as adding a load on a loop) invalidates the mesh and you will need to re-mesh. You should apply loads to the model before meshing when using these controls. Refer to Protecting Topology Defined Prior to Meshing for related information.
The options for defining loop removal are described below.
Sheet Loop Removal
The Sheet Loop Removal control determines whether loops will be removed (meshed over) by the mesher. When Sheet Loop Removal is set to , the mesher removes any loop with a radius less than or equal to the value of Loop Removal Tolerance.
Valid values are and . The default is .
Loop Removal Tolerance
The Loop Removal Tolerance control sets the tolerance for loop removal. Any loop with a radius less than or equal to the value of Loop Removal Tolerance will be meshed over by the mesher.
Specify a value greater than .
