Model.contactsurfcreatewithfaces

Model.contactsurfcreatewithfaces(name, color, elem_collection, node_collection, break_angle, reverse_normals, on_face)

Creates a contact surface using 2D element edges or 2D/3D element faces.

Parameters:

• name (hwString) – The name of the contact surface to create.

• color (int) – The color of the contact surface. Valid values are 1 through 64.

• elem_collection (Collection) – The collection containing the element entities to use.

• node_collection (Collection) – The collection containing the containing the node entities that define an edge or a face of an element.

• break_angle (double) – The break angle for finding adjacent elements.

• reverse_normals (int) –

  0 - Create contact surface along element normal.

  1 - Create contact surface opposite element normal.

• on_face (int) –

  0 - Create contact surface on edge.

  1 - Create contact surface on face.

Example

Create a contact surface named “test” with elements with IDs 1-100 with faces defined by nodes with IDs 1-5 and a breakangle of 30.0

import hm
import hm.entities as ent

model = hm.Model()

model.contactsurfcreatewithfaces(
    name="test",
    color=5,
    elem_collection=hm.Collection(model, ent.Element, list(range(1, 101))),
    node_collection=hm.Collection(model, ent.Node(model, list(range(1, 6)))),
    break_angle=30.0,
    reverse_normals=0,
    on_face=1,
)
