Model.createweldelemsfromalinelist(surf1_collection, surf2_collection, tol, createplot, configval, syst, code, num_nodes, linelist1, nodelist1, biasstyle, biasingintensity, spacing, offset_type, endoffset, property)

Creates weld elements between surfaces using a line list to determine the weld points.

Parameters:

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

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

• 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).

• linelist1 (EntityList) – A list containing the line entities.

• nodelist1 (EntityList) – A list containing the node 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 the property.

Example

Create five equally spaced spotwelds on different lines : Lines with IDs 95 , 96 , and 97 are joined together into a single line . Each of these nodes is projected normally on the two surfaces ( IDs 237 and 253 ) within a tolerance of 1.0 . Then the two surfaces are welded together at the projection points

import hm
import hm.entities as ent

model = hm.Model()

Lines = [ent.Line(model,95), ent.Line(model,96), ent.Line(model,97)]
Filter = hm.FilterByCollection(ent.Node, ent.Line)
Line_col = hm.Collection(Lines)
Nodes = [n for n in hm.Collection(model, Filter, Line_col)]

model.createweldelemsfromalinelist(
    surf1_collection=hm.Collection(model,ent.Surface,[237]),
    surf2_collection=hm.Collection(model,ent.Surface,[253]),
    tol=1.0,
    createplot=1,
    configval=3,
    syst=0,
    code=0,
    num_nodes=5,
    linelist1=Lines,
    nodelist1=Nodes,
    biasstyle=1,
    biasingintensity=0.0,
    spacing=0.0,
    offset_type=0,
    endoffset=0.0,
    property="myprop",
)

Create the same with spacing value of 2.0 and half spacing option

import hm
import hm.entities as ent

model = hm.Model()

Lines = [ent.Line(model,95), ent.Line(model,96), ent.Line(model,97)]
Filter = hm.FilterByCollection(ent.Node, ent.Line)
Line_col = hm.Collection(Lines)
Nodes = [n for n in hm.Collection(model, Filter, Line_col)]

model.createweldelemsfromalinelist(
    surf1_collection=hm.Collection(model,ent.Surface,[237]),
    surf2_collection=hm.Collection(model,ent.Surface,[253]),
    tol=1.0,
    createplot=1,
    configval=3,
    syst=0,
    code=0,
    num_nodes=5,
    linelist1=Lines,
    nodelist1=Nodes,
    biasstyle=1,
    biasingintensity=0.0,
    spacing=2.0,
    offset_type=1,
    endoffset=0.0,
