Model.rbe3#

Model.rbe3(collection, independent_dofs, independent_weights, dependent_node, dof, weight)#

Creates an RBE3 element.

Parameters:

  • collection (Collection) – The collection containing the independent nodes.

  • independent_dofs (hwIntList) – The list of the integers containing the degrees of freedom for which each respective independent node of the element is active (any of the digits 1-6).

  • independent_weights (hwDoubleList) – The list of the doubles containing the weight for each respective independent node.

  • dependent_node (Entity) – The dependent node of the element. If set to None, the dependent node will be auto-created at the centroid of the independent nodes.

  • dof (hwBoolList) – The list of Boolean values representing the degrees of freedom for which the dependent node of the element is active.

  • weight (double) – The weight assigned to the dependent node.

Example#

Create an RBE3 element with dependent node ID 100 and independent nodes ID 101 , 102 , and 103 with all of the nodes have all six degrees of freedom and a weight of 1.23#
import hm
import hm.entities as ent

model = hm.Model()

# Creating collection containing node with ID 101, 102, 103
input_collection = hm.Collection(model, ent.Node, [101, 102, 103])
model.rbe3(
        collection=input_collection,
        independent_dofs=[123456, 123456, 123456],
        independent_weights=[1.23, 1.23, 1.23],
        dependent_node=ent.Node(model,100),
        dof=[True,True,True,True,True,True],
        weight=1.23
)
