Model.linemesh_preparedata1#

Model.linemesh_preparedata1(collection, break_angle, config)#

Prepares the selected entities for 1D meshing.

Each call to this function must be paired with a call to Model.linemesh_savedata1() or Model.linemesh_savedata_bar1() to clean up memory.

Parameters:

  • collection (Collection) – The collection containing the entities to 1D mesh. Valid entity types are lines and nodes. If collection of nodes is provided, then only two nodes can be provided.

  • break_angle (double) – If the angle between the lines’ tangents at a joint is greater than this value, the line is split to force a node at that location. If set to break_angle=0.0, no split will occur.

  • config (int) – The configuration of the element to create. Only 1D configs are valid.

Example#

Meshing lines with IDs 15 and 18 with a 30 degree break angle, creating rigid elements with no property#
import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection of line entities which we will
# prepare for 1D meshing.
line_collection = hm.Collection(model, ent.Line, [15, 18])

model.linemesh_preparedata1(collection=line_collection, break_angle=30.0, config=5)

# Assing meshing parameters to line segments for 1D meshing.
model.linemesh_saveparameters(segment=0, density=3, bias=0, bias_style=0)

model.linemesh_saveparameters(segment=1, density=2, bias=0, bias_style=0)

# Creating 1D elements and cleans up memory.
model.linemesh_savedata1(create_flag=1, config=5, property_id=0, organize=0)
