Model.createweldsbetweenelemsusingnodes

Model.createweldsbetweenelemsusingnodes(elem1_collection, elem2_collection, single_col, node_collection, tol, syst, configval, property, remesh)

Creates weld element(s) between pre-existing elements at the given node(s).

Parameters:

• elem1_collection (Collection) – The collection containing the element entities for the first element collector.

• elem2_collection (Collection) – The collection containing the element entities for the second element collector, if given.for the second comp collector, if given.

• single_col (int) –

  Flag for the number of element collectors used:

  1 - One element collector.

  0 - Two element collectors.

• node_collection (Collection) – The collection containing the node entities.

• tol (double) – The maximum distance allowed between the node (from the node collection) and the element (from the element collection) to weld this element.

• syst (int) –

  Systems flag:

  1 - Build systems.

  0 - Do NOT build systems.

• configval (int) –

  Type of weld element created:

  2 - plot

  3 - weld

  5 - rigid

  21 - spring

  60 - bar

  61 - rod

  70 - gap

• property (hwString) – Name of the property collector. Used to retrieve the property ID.

• remesh (int) – Remesh flag (always 0).

Example

Each of the three nodes on the collection with IDs (16, 17, and 18) try to project normally onto as many elements as they can that are within a tolerance of 1.0. All of the non-adjacent elements found for each node’s projections are then welded together at their projection points

import hm
import hm.entities as ent

model = hm.Model()

elems1 = hm.Collection(model, ent.Element, populate=True)
elems2 = hm.Collection(model, ent.Element, populate=False)
nodes = hm.Collection(model, ent.Node, [16, 17, 18])

model.createweldsbetweenelemsusingnodes(
    elem1_collection=elems1,
    elem2_collection=elems2,
    single_col=1,
    node_collection=nodes,
    tol=1.0,
    syst=1,
    configval=3,
    property="myprop",
    remesh=0,
)
