Model.createnodesandspotweldelems(surf1_collection, surf2_collection, tol, createplot, configval, syst, code, num_nodes, collection, biasstyle, biasingintensity, spacing, offset_type, endoffset, property)

Creates nodes and spotweld elements between two surfaces on the selected lines at a specified spacing or density with an element type, coordinate system, and property ID.

Parameters:

• surf1_collection (Collection) – The collection containing the first surface entities.

• surf2_collection (Collection) – The collection containing the second surface entities.

• tol (double) – Search tolerance to identify the surfaces.

• createplot (int) – Creates a plot.

• configval (int) – Element type configuration value.

• syst (int) –

  Local coordinate system switch.

  0 - Do not build systems.

  1 - Build systems.

• code (int) –

  Code for one or all surface options.

  0 - All surfaces.

  1 - One surface.

• num_nodes (int) – Number of nodes on the line (for Density option only).

• collection (Collection) – The collection containing the line entities.

• biasstyle (int) – 1 - Linear.

• biasingintensity (double) – 0.0 - Equal spacing.

• spacing (double) –

  Spacing between weld elements.

  0.00 for Density option.

• offset_type (int) –

  0 - End offset.

  1 - Half spacing.

• endoffset (double) – End offset from the edge (= value).

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

Examples

Create five spotwelds ( bar2 elements ) between surfaces with IDs 1 and 2 , use the all surfaces option , within a tolerance of 0.01 along four marked lines at equal spacing . Elements are created without a coordinate system and with a property collector named “ name_prop “

import hm
import hm.entities as ent

model = hm.Model()

model.createnodesandspotweldelems(
    surf1_collection=hm.Collection(model,ent.Surface,[1]),
    surf2_collection=hm.Collection(model,ent.Surface,[2]),
    tol=0.01,
    createplot=1,
    configval=60,
    syst=0,
    code=0,
    num_nodes=5,
    collection=hm.Collection(model,ent.Line,[1,2,3,4]),
    biasstyle=1,
    biasingintensity=0.0,
    spacing=0.0,
    offset_type=0,
    endoffset=0.0,
    property="name_prop",
)

Creatingreate the same as the first example with an end offset value of 2.0

import hm
import hm.entities as ent

model = hm.Model()

model.createnodesandspotweldelems(
    surf1_collection=hm.Collection(model,ent.Surface,[1]),
    surf2_collection=hm.Collection(model,ent.Surface,[2]),
    tol=0.01,
    createplot=1,
    configval=60,
    syst=0,
    code=0,
    num_nodes=5,
    collection=hm.Collection(model,ent.Line,[1,2,3,4]),
    biasstyle=1,
    biasingintensity=0.0,
    spacing=0.0,
    offset_type=0,
    endoffset=2.0,
    property="name_prop",
)
