Description

Finds flanges in shell meshes that are within a specified proximity. Flanges are found on elements or components specified by a previous call to *findflangestoposhell, but can also be found within the specified proximity of non-flange areas. Note that at least one side must have been identified as a flange. The output is either a mark, elements, or the creation of duplicate elements denoting where flanges where identified. This can also be used to create auto-pitch points.

The process of finding flanges requires the initialization of the process using *findflangesinit. This initialization process requires the components or elements utilized by subsequent * findflangestoposhell and *findflangesproximityshell commands. To utilize different input components or elements, the *findflangesinit command needs to be rerun. After completing the find flanges process, the command *findflangesend should be called to clear the memory.

Inputs

mark_id: The mark ID containing the output flange elements. Valid values are 1 and 2.; If set to 0, duplicate elements are constructed from the identified elements and placed in the component ^face_flange_prox_shell.; The output_elems argument is used to decide what types of elements are output.
non-flanges: Defines if proximity should be extended to elements not identified as flanges. Valid values are:; 0 - Only elements on flanges considered.; 1 - Elements on one flange with other not on flange.; 2 - Elements need not be on flanges
max_proximity: The distance that defines the maximum proximity to use.
max_align: The maximum angle between normals of facing elements.
auto_pitch_comp: Defines the component for auto pitch points. Valid values are:; < 0 - Use current component; > 0 - Use specified component ID; = 0 - Do not build
auto_pitch_spacing: Defines the spacing for auto-pitch points. Points are not created if set to 0.0.
auto_pitch_offset: Defines the initial offset for auto-pitch points. If set to 0.0, auto_pitch_spacing/2 is used.
auto_pitch_edge_distance: Defines the distance from the free edge for auto-pitch points.
output: The output type. Valid values are:; 0 - No output; 1 - Output all flange elements found within proximity; 2 - Output elements on flanges not within proximity; 3 - Output elements on flanges from which no auto-pitch points were created
create_points_in_middle: 0 - Auto-pitch points are created on one of the flanges (default).; 1 - Auto-pitch points are created at the midplane of the flanges.
reserved: Reserved for future use. Must be set to 0.

Example

To find all flanges in shell elements of the displayed components using a feature angle of 30 degrees, and to create auto-pitch points using a search distance of 0.5, a spot pitch distance of 1.5, an end offset of 2.0, and a free edge distance of 0.1:

*createmark comps 2 displayed
*findflangesinit components 2 2 30 0 0 0
*findflangestoposhell 0 1 4.0 0.0 0.0 0.0 0.0 0 0 0 0.5 0.5 0.0 45.0 0 0 0 0.0
*findflangesproximityshell 0 1 0.5 45.0 -1 1.5 2.0 0.1 0 0 0.0
*findflangesend

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
