Model.linemesh_savedata_bar1#

Model.linemesh_savedata_bar1(entity_type, create_flag, config, property_id, vector, offset_x_a, offset_y_a, offset_z_a, offset_x_b, offset_y_b, offset_z_b, auto_flag, organize)#

Creates 1D elements, with options for bar2 elements, and cleans up memory.

Each call to this function must be paired with a previous call to Model.linemesh_preparedata1() or Model.linemesh_preparenodeslist1().

Parameters:

entity_type (EntityFullType) – The type of entity to 1D mesh. Valid values are lines and nodes.
create_flag (int) –
Flag for generating elements:

0 - Do not generate elements.

1 - Generate elements.
config (int) – The 1D element config ID of the elements to create. For bar2 elements, this should be set to 60.
property_id (int) – The ID of the property to assign to the 1D elements.
vector (hwTriple) – The hwTriple object defining the y-axis vector components. User can also supply a Python list of three doubles. This argument is only used if auto_flag=0 and config=60.
offset_x_a (double) – The offset in the x-direction at end a. This argument is only used if config=60.
offset_y_a (double) – The offset in the y-direction at end a. This argument is only used if config=60.
offset_z_a (double) – The offset in the z-direction at end a. This argument is only used if config=60.
offset_x_b (double) – The offset in the x-direction at end b. This argument is only used if config=60.
offset_y_b (double) – The offset in the y-direction at end b. This argument is only used if config=60.
offset_z_b (double) – The offset in the z-direction at end b. This argument is only used if config=60.
auto_flag (int) – If set to 0, vector is used. Otherwise, vector type is set to auto. This argument is only used if config=60.
organize (int) –
Organizing new 1D elements:

0 - Organize new 1D elements to current component.

1 - Organize new 1D elements to input lines component(s).

Examples#

Mesh lines with IDs 15 and 18 with a 30 degree break angle, creating bar2 elements with no property or offset and using the auto vector#

import hm.entities as ent

model = hm.Model()

# prepare for 1D meshing.
line_collection = hm.Collection(model, ent.Line, [15, 18])

# Assing meshing parameters to line segments for 1D meshing.
