Model.assignsystem_fromcurves#

Model.assignsystem_fromcurves(collection, geom_collection, size, color, only_orient, rebar=0, table_id=0, reverse_flag=0)#

Assigns a system to an entity type based on lines. The axis of the system is then projected on the element/property plane. It also re-orients and visualizes the element (material) coordinate system for selected entities. When review is complete, the function Model.vectorsoff() must be run. This function is currently supported for Abaqus, Nastran and OptiStructsolvers.

Parameters:

  • collection (Collection) – The collection containing the entities. Supported entities are elements and properties.

  • geom_collection (Collection) – The collection containing the entities from which the system will be referenced. Supported entities are nodes and lines.

  • size (double) – If only_orient=1, this defines the size of the displayed vectors. If set to 0, the size will be determined automatically.

  • color (int) – The color of the vectors or lines. Valid values are 1 through 64.

  • only_orient (unsigned int) –

    0 - The new x-element directions are shown as continuous gradient lines starting and ending on free edges.

    1 - The new x-element directions are displayed as vectors starting from the element centroid.

  • rebar (unsigned int) – The rebar value, valid only for Abaqus user profile.

  • table_id (int) – The ID of the distribution table. For Abaqus, the distribution table with this table ID will be updated accordingly. For Nastran and Optistruct, the only valid value is 0 and a distribution table is created and updated internally.

  • reverse_flag (unsigned int) –

    0 - The line’s direction will not be flipped.

    1 - The line’s direction will be flipped.

Example#

Project the axis of the line with ID 210 on the element plane of all the elements , and display the projection as cyan vectors (color=7 ) with size=3.0 , without flip the direction#
import hm
import hm.entities as ent

model = hm.Model()

elem_col = hm.Collection(model, ent.Element)
line_col = hm.Collection(model, ent.Line, [210])

model.assignsystem_fromcurves(
collection=elem_col,
geom_collection=line_col,
size=3.0,
color=7,
