hm_flangedetectioninit

Syntax

hm_flangedetectioninit entity_type mark_id ?consider_geom=<mode>?

Type

HyperMesh Tcl Query

Description

Initializes the flange detection module. This must precede any calls to other hm_flangedetection* APIs, and must be followed by a call to hm_flangedetectionend.

"Major" database changes made while inside of the flange detection module will invalidate and delete any results.

Inputs

entity_type

The type of entities to find flanges for. Valid values are comps, surfs, and elems.

mark_id

The ID of the mark containing the entities. Valid values are 1 and 2.

consider_geom=<mode>

Used when entity_type is comps:

0 - Use elements from the comps (default if not specified)

1 - Use geometry from the comps

Examples

To find 2D flanges from elements in all components, using a min width of 2, a max width of 20 and a feature angle of 20, and write out all flange details to a file named C:/temp/flanges.txt:

set flangesfile [open "C:/temp/flanges.txt" "w"]
*createmark comps 1 all
hm_flangedetectioninit comps 1
hm_flangedetectionsetparams min_width=2.0 max_width=20 feature_angle=20
hm_flangedetectionfindflanges 1
set n [hm_flangedetectiongetnumberofflanges]
if { $n > 0 } {
    puts $flangesfile "Number of flanges = $n"
    puts $flangesfile "Flanges details"
    for {set i 0} {$i < $n} {incr i} {
        puts $flangesfile "$i details = [hm_flangedetectiongetflangedetails $i]"
        puts $flangesfile "$i midline = [hm_flangedetectiongetmidline $i 0]"
    }
    hm_flangedetectionfindmates
    set m [hm_flangedetectiongetnumberofmatinggroups]
    if { $m > 0 } {
        for {set i 0} {$i < $m} {incr i} {
            puts $flangesfile "$i = [hm_flangedetectiongetmatinggroupdetails $i]"
        }
    } else {
        puts $flangesfile "Flange mates not detected."
    }
} else {
    puts $flangesfile "Flanges not detected."
}
hm_flangedetectionend
close $flangesfile
