Description
|
||||
Selects a section of mesh based on a cellSet.
|
||||
|
||||
The utility sub-sets the mesh to choose only a part of interest. Check
|
||||
the setSet/cellSet utilities to see how to select cells based on various.
|
||||
|
||||
The mesh will subset all points, faces and cells needed to make a sub-mesh
|
||||
but will not preserve attached boundary types.
