wrap

Mesh.wrap(min_size=None, max_size=None, growth_rate=1.2, elements_per_gap=None, normal_angle=18.0, input_parts='*', input_labels='*', keep_inputs=False, region_extract=WrapRegion.EXTERNAL, material_point=None, extract_features=True, create_intersection_loops=False, use_existing_features=False, enable_feature_octree_refinement=True, feature_angle=40.0, contact_prevention_size=None, number_of_threads=None, remesh_postwrap=True, recompute_remesh_sizes=False, use_existing_size_fields=False, size_fields=None, wrap_size_controls=None, remesh_size_controls=None, feature_recovery_params=None, contact_prevention_params=None, leak_prevention_params=None)

Wrap and remesh the input.

The default behavior is to perform an external wrap of all parts in the model using curvature sizing and extracting features. The wrap is then remeshed to provide a surface mesh for the extracted region.

Geodesic sizing is used only if soft and curvature controls are set. If contact prevention size is set and geodesic sizing is available, contact detection is used globally.

If minimum and maximum sizes are provided, variable size mesh is generated between the minimum size and maximum size by applying sizes based on curvature.

If either minimum size or maximum size is provided, constant size mesh is generated with the provided size.

If neither minimum size or maximum size is provided, global minimum and maximum settings are used to generate a variable size mesh based on curvature.

• Parameters:

  min_size : Minimum edge length of the mesh. The default is None.
