Model.adjustgroupsnormal

Model.adjustgroupsnormal(name, main_flag, collection, elem_flag, orientation_element, reverse_normal)

Adjusts a group normal using an orientation element.

Parameters:

• name (hwString) – The name of the group entity to adjust. User can directly supply a Python string.

• main_flag (int) –

  0 - Use secondary

  1 - Use main

• collection (Collection) – The collection containing the elements to adjust.

• elem_flag (int) –

  Flag for reversing the contact normal of all or individual elements of the group.

  0 - All elements, collection is ignored

  1 - Individual elements, collection is used

• orientation_element (unsigned int) – The ID of the shell element that should be used for shell group normal correction on shell face. This element should be part of the selection.

• reverse_normal (int) –

  0 - Correct group normal along the direction of orientation_element normal

  1 - Correct group normal opposite to the direction of orientation_element normal

Examples

Reverse the normal of all main elements of the group “ test “

import hm
import hm.entities as ent

model = hm.Model()
model.adjustgroupsnormal(
    name="test",
    main_flag=1,
    collection=hm.Collection(model,ent.Element,populate=False),
    elem_flag=0,
    orientation_element=0,
    reverse_normal=0
)

Reverse the normal of all secondary elements of the group “ test “

import hm
import hm.entities as ent

model = hm.Model()
model.adjustgroupsnormal(
    name="test",
    main_flag=0,
    collection=hm.Collection(model,ent.Element,populate=False),
    elem_flag=0,
    orientation_element=0,
    reverse_normal=0
)

Adjust the normal of group “ test “ for the elements with IDs 12 , 23 , 29 , and 53 in the normal direction of reference element with ID 23

import hm
import hm.entities as ent

model = hm.Model()
elems = hm.Collection(model, ent.Element, [12,23,29,53])
model.adjustgroupsnormal(
    name="test",
    main_flag=1,
    collection=elems,
    elem_flag=1,
    orientation_element=23,
    reverse_normal=0
)

Adjust the normal of group “ test “ for the elements with ID 12 , 23 , 29 , and 53 in the reverse normal direction of reference element with ID 23

import hm
import hm.entities as ent

model = hm.Model()
elems = hm.Collection(model, ent.Element, [12,23,29,53])
model.adjustgroupsnormal(
    name="test",
    main_flag=1,
    collection=elems,
    elem_flag=1,
    orientation_element=23,
    reverse_normal=1
)
