hm_holedetectionsetholeparams
Defines parameters for finding 2D holes in both geometry and FE.
Syntax
hm_holedetectionsetholeparams hole_shape=<> ?parameter1=<>? ?parameter2=<>? etc...
Type
HyperMesh Tcl Query Command
Description
Defines parameters for finding 2D holes in both geometry and FE. Multiple calls to this command can be made to override or redefine the parameters for each hole shape. Settings are cleared on any call to hm_holedetectioninit/hm_holedetectionend.
This must be preceded by a call to hm_holedetectioninit.
Only hole_shape is mandatory. All other parameters are optional and have default values. Parameters can be specified in any order.
Inputs
- hole_shape=
- The shape of hole the parameters are being defined for. Bit values are used and the
value is calculated as (Bit0 + 2*Bit1 + 4*Bit2 + 8*Bit3 + 16*Bit4).
- Bit0
- 0 - Do not consider general holes
- Bit1
- 0 - Do not consider circular holes
- Bit2
- 0 - Do not consider rounded holes.
- Bit3
- 0 - Do not consider square holes.
- Bit4
- 0 - Do not consider rectangular holes.
- ?hole_type=<>?
- The hole type to consider. If 0 (default), the holes type check is skipped. Bit values
are used and the value is calculated as (Bit0 + 2*Bit1 + 4*Bit2 + 8*Bit3).
- Bit0
- 0 - Do not consider surface holes.
- Bit1
- 0 - Do not consider flanged surface holes
- Bit2
- 0 - Do not consider cylindrical holes.
- Bit3
- 0 - Do not consider conical holes.
- ?max_avg_adj_surf_angle=<>?
- Maximum average angle deviation of holes axial direction of adjacent surfaces normals. Acceptable values are [0.0, 90.0]. If less than 0.0, this check is skipped. Default value 45 degrees.
- ?max_big_planar_dim=<>?
- This threshold applies to the rounded (elongated) and rectangular holes. The maximum planar dimension of the hole cannot exceed this value. If less than or equal to 0.0, this check is skipped. Default value 0.0.
- ?max_geom_angle_dev_abs=<>?
- Sets the absolute angle threshold for deviation of corner angles of rectangular holes from right angle, see holes_shape. Acceptable values are [0.0, 90.0], otherwise the closer extreme is used. If less than 0.0, this check is skipped. Default value -1.
- ?max_geom_dev_abs=<>?
- Sets the absolute threshold for linear hole shape deviation, see hole_shape. If less than 0.0, this check is skipped. Default value -1.
- ?max_geom_dev_percent=<>?
- Sets the relative threshold for hole linear and angle shape deviation, see hole_shape. Acceptable values are [0.0, 100.0], otherwise the closer extreme is used. If less than 0.0, this check is skipped. Default value -1.
- ?max_offset_plane_dev=<>?
- 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. Default value 0.0.
- ?max_planar_dim=<>?
- The maximum width of the hole cannot exceed this value. If less than or equal to 0.0, this check is skipped. Default value 0.0.
- ?max_smooth_edge_angle=<>?
- See hole_shape. Acceptable values are [0.0, 90.0], otherwise the closer extreme is used. If less than 0.0, this check is skipped. Default value -1.
- ?max_straightness_dev_percent=<>?
- Sets the relative threshold for the chordal deviation of the sides of rectangular holes of straight lines, see hole shape. Acceptable values are [0.0, 100.0], otherwise the closer extreme is used. If less than 0.0, this check is skipped. Default value -1.
- ?min_planar_dim=<>?
- The minimum width of the hole must exceed this value. If less than or equal to 0.0, this check is skipped. Default value 0.0.
