Model.createweldsbetweenelemsusingpoints

Model.createweldsbetweenelemsusingpoints(elem1_collection, elem2_collection, single_col, point_collection, tol, syst, configval, property, remesh)

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

• single_col (int) –

  Flag for the number of element collectors used:

  1 - One elem collector.

  0 - Two elem collectors.

• point_collection (Collection) – The collection containing the point entities.

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

• syst (int) –

  Systems flag:

  1 - Build systems.

  0 - Do NOT build systems.

• configval (int) –

  Weld element type 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 zero).

Example

Each of the three points on the mark (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 point’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)
points = hm.Collection(model, ent.Point, populate=True)

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