Model.adjustcontactsurfacenormal#

Model.adjustcontactsurfacenormal(name, collection, elem_flag, orientation_element, reverse_normal)#

Adjusts a contact surface normal using an orientation element.

Parameters:

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

  • 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 contact surface.

    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 contact surface normal correction on shell face. This element should be part of the selection.

  • reverse_normal (int) –

    0 - Correct contact normal along the direction of orientation_element normal

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

Examples#

Adjust the normal of contactsurf “ 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.adjustcontactsurfacenormal(
    name="test",
    collection=elems,
    elem_flag=1,
    orientation_element=23,
    reverse_normal=0
)
Adjust the normal of contactsurf “ test “ for the elements with IDs 12 , 23 , 29 , and 53 in the reverse normal direction of reference element with ID 23#
import hm
