Model.setredoconnectparams

Model.setredoconnectparams(mesh_side, num_layers)

Specifies parameters for redo connectivity element remeshing.

Use of this function implies that it will be followed by a function that performs remeshing/meshing by elements with redo option selected.

Parameters:

• mesh_side (int) –

  Flag indicating where the transition from existing element density to selected density occurs:

  0 - Transition starts at border formed by selected elements and goes num_layers outside (default)

  1 - Transition starts at border formed by selected elements and goes num_layers inside

• num_layers (int) – The number of layers for transitioning from existing element density to selected density. (default = 2)

Examples

Remesh the elements with IDs 1 - 40 , redo connectivity option selected and transition from current element size to element size of 10.0 occur in two layers of elements outside the border formed by selected elements

import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the elements with IDs 1-40
filter_elements = hm.FilterByEnumeration(ent.Element, list(range(1, 41)))
elements_collection = hm.Collection(model, filter_elements)

model.setredoconnectparams(mesh_side=0, num_layers=2)

model.defaultmeshelems(
    collection=elements_collection,
    elem_size=10.0,
    elem_type=2,
    elem_type_2=2,
    comp_mode=0,
    size_control=1,
    skew_control=1,
    edge_mesh_type=1,
    min_size=0.0,
    max_size=0.0,
    max_deviation=0.0,
    max_angle=0.0,
    previous_settings=3,
    vertex_angle=30.0,
)

Remesh the elements with IDs 1 - 40 , redo connectivity option selected and transition from current element size to element size of 4.0 occur in three layers of elements inside the border formed by selected elements

import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the elements with IDs 1-40
filter_elements = hm.FilterByEnumeration(ent.Element, list(range(1, 41)))
elements_collection = hm.Collection(model, filter_elements)

model.setredoconnectparams(mesh_side=1, num_layers=3)

model.defaultmeshelems(
    collection=elements_collection,
    elem_size=4.0,
    elem_type=2,
    elem_type_2=2,
    comp_mode=0,
    size_control=1,
    skew_control=1,
    edge_mesh_type=1,
    min_size=0.0,
    max_size=0.0,
    max_deviation=0.0,
    max_angle=0.0,
    previous_settings=3,
    vertex_angle=30.0,
)
