Model.failed_elements_cleanup

Model.failed_elements_cleanup(collection, elem_type, min_elemsize, max_feature_angle, max_reverse_angle)

Cleans up the mesh by eliminating reversed and small sized elements. May create new elements instead of reversed.

Parameters:

• collection (Collection) – The collection containing the element entities of the original mesh.

• elem_type (int) –

  Determines the type of new elements:

  0 - trias

  1 - mixed type (quads and trias)

• min_elemsize (double) – Determines minimum element size of elements in the mesh after cleanup.

• max_feature_angle (double) – Determines mesh feature angle for keeping features when possible after cleanup.

• max_reverse_angle (double) – Determines maximum angle between adjacent element normals for reversed elements detection.

Example

Eliminate elements in the displayed tria mesh with size less than 1.5, remove reversed elements with adjacent normals greater than 150 degrees, trying to keep features greater than 60 degrees

import hm
import hm.entities as ent

model = hm.Model()

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

model.failed_elements_cleanup(
    collection=element_collection,
    elem_type=0,
    min_elemsize=1.5,
    max_feature_angle=60.0,
    max_reverse_angle=150.0,
)
