Model.optimized_elements_remesh2(collection, criteria_file, elem_size, elem_type, feature_angle, vertex_angle, comp_mode, break_flag, algorithm)#

Remeshes elements with the selection of the best meshing algorithm and optimization of node positions.

Parameters:

  • collection (Collection) – The collection containing the element entities to remesh.

  • criteria_file (hwString) – The path and file name of the criteria file. Set the value to “dummy” to use the default file.

  • elem_size (double) – The default element size used to calculate element densities along edges, when necessary. Element sizes along shared edges cannot be changed.

  • elem_type (int) –

    The type of elements to create. Valid values are:

    0 - trias

    1 - quads

    2 - mixed

    3 - right trias

    4 - quads only

  • feature_angle (double) – The angle, in degrees, specifying the feature lines. This is approximately the minimal internal angle between the elements adjacent to a feature line. Valid values are between 18-90 degrees.

  • vertex_angle (double) – The angle between two edge segments when a vertex is created.

  • comp_mode (int) –

    A flag that specifies how the elements are organized. Valid values are:

    0 - Elements are created in the current component.

    1 - Elements are created in the same component as their parent surface(s).

  • break_flag (int) –

    Determines if connectivity will be broken along shared edges between elements when a different element size is chosen. Valid values are:

    0 - Do not break connectivity.

    1 - Break connectivity.

  • algorithm (int) –

    Determines the algorithm for meshing. Valid values are:

    0 - Standard meshing

    1 - Meshing with flow “align” control

    3 - Meshing with flow “align” and “size” control

Example#

Re - mesh the displayed elements with element size 10 , mixed elements type , and optimize node positions use * default * criteria file (criteria_file="dummy " ) , feature and vertex angle of 30 degrees , and meshing flow with align and size control#
import hm
import hm.entities as ent

model = hm.Model()

remesh_elems_col = hm.CollectionByDisplayed(model, ent.Element)
