Description
Finds holes in solid meshes. The solid elements are bounded by two connected and closed sequences of feature edges subject to the specified parameters. Note that only holes with two such sequences are found. Each sequence is referred to as a "rim". The output is shell elements for bounding faces of holes, and plot elements for rim perimeters.
The process of finding holes requires the initialization of the process using *findholesinit. This initialization process requires the components or elements utilized by subsequent *findholesshell and *findholessolid commands. To utilize different input components or elements, the *findholesinit command needs to be rerun. After completing the find hole process, the command *findholesend should be called to clear the memory.
Inputs
- hole_type
- The type of hole to find. Valid values are:
- 0 - any
- 1 - circular
- 2 - square
- 3 - rectangular
- min_height
- The distance between the center of the rims must exceed this value. If less than or equal to 0.0, this check is skipped.
- max_height
- The distance between the center of the rims cannot exceed this value. If less than or equal to 0.0, this check is skipped.
- min_cone_angle
- The inward facing normal direction of all faces comprising the wall of the hole must make this angle with respect to the primary axis. The primary axis is between the centers of the rims. If less than or equal to 0.0, this check is skipped. A value of 45.0 is recommended.
- max_offset_angle
- The normal associated with each rim must not differ by more than this angle from the primary axis. If less than or equal to 0.0, this check is skipped. A value of 45.0 is recommended.
- min_planar_dim
- Applied to each rim. The minimum planar dimension of the hole must exceed this value. If less than or equal to 0.0, this check is skipped.
- max_planar_dim
- Applied to each rim. The maximum planar dimension of the hole cannot exceed this value. If less than or equal to 0.0, this check is skipped.
- max_offset_plane_dev
- Applied to each rim. No node on the perimeter of a hole must exceed this distance from the mean plane. If less than or equal to 0.0, this check is skipped.
- max_geom_dev_percent
- See hole_type. Acceptable values are [0.0, 100.0], otherwise closer extreme is used. If less than or equal to 0.0, this check is skipped.
- max_smooth_edge_angle
- See hole_type. Acceptable values are [0.0, 90.0], otherwise closer extreme is used.
- capped_holes_filter
- A flag used to define how capped holes are handled. Valid values are:
- 0 - Output both open holes and those capped on one side.
- 1 - Output only open holes.
- 2 - Output only holes capped on one side.
- organize
- A flag used to define how found edge plot elements are organized. Valid values are:
- 0 - Place found edge plot elements in ^edge_holes_shell component.
- 1 - Place found edge plot elements in current component.
- create_hole_edges
- A flag used to define if plot elements are created. Valid values are:
- 0 - Plot elements are not created.
- 1 - Plot elements are created.
- flag
- Reserved for future use. Set to 0.
- param
- Reserved for future use. Must be set to 0.
