To automatically detect and collapse regions of faces narrower than a specified size, in the Geometry toolbar, from the
Virtual Operations menu (
), select
Collapse Face Regions (
). You can also select it from the
Geometry node’s context menu’s
Virtual Operations submenu. Such narrow regions of faces can cause unwanted mesh refinement or even meshing failure. The collapse face regions operation determines narrow regions of a face and then collapses those resulting sliver faces.
Select the faces for which you want to collapse narrow face regions in the Graphics window. They then appear in the
Faces list. If the geometry sequence includes user-defined selections above the
Collapse Face Regions node, choose
Manual to select faces, or choose one of the selection nodes from the list next to
Faces.
Click the Active button to toggle between turning ON and OFF the
Faces selections.
By default, the Narrow regions tolerance list is set to
Automatic. Select
Manual to enter a value in the
Maximum width field that appears. The tolerance is the maximum width of a face region to be considered as narrow. If you build the operation with
Automatic and then switch to
Manual, the
Maximum width field shows the value of the parameter that was used when the operation was built.
