Model.barelement#

Model.barelement(node1, node2, vector, orientation_node, y_dir, pin_flags_a, pin_flags_b, property_name)#

Creates a bar element.

Parameters:

  • node1 (Entity) – The first node ID (end a).

  • node2 (Entity) – The second node ID (end b).

  • vector (hwTriple) – The hwTriple object defining the vector components. User can also supply a Python list of three doubles.

  • orientation_node (Entity) – The orientation node ID. If set to None, then vector is used. If non-zero, then y_dir specifies whether this node defines the local y- or local z-axis.

  • y_dir (int) – If set to 1, then orientation_node defines the local y-axis of the bar. Otherwise, orientation_node defines the local z-axis.

  • pin_flags_a (hwBoolList) – The pin flags at end a. A pin flag of None passes forces in all degrees of freedom.

  • pin_flags_b (hwBoolList) – The pin flags at end b. A pin flag of None passes force in all degrees of freedom.

  • property_name (hwString) – The name of the property collector assigned to the bar.

Example#

Create a bar3 element between nodes with IDs 101 and 102 with its local y-axis defined by the vector (1, 0, and 0) and assigned property prop1#
import hm
import hm.entities as ent

model = hm.Model()

model.barelement(
        node1=ent.Node(model, 101),
        node2=ent.Node(model, 102),
        vector=(1, 0, 0),
        orientation_node=None,
        y_dir=0,
        pin_flags_a=None,
        pin_flags_b=None,
        property_name="prop1"
)
