Model.voxel_lattice_hex_mesh_add_entities

Model.voxel_lattice_hex_mesh_add_entities(collection, mode)

Adds entities to the voxel domain. Voxel gridding is done along the intersection profile of the entities. This must be preceded by a call to Model.voxel_lattice_hex_mesh_init() and must be followed by a call to Model.voxel_lattice_hex_mesh_create().

Parameters:

• collection (Collection) – The collection containing the entities to be added. Valid entities are component, element, surface, solid and line entities.

• mode (int) –

  1 - Voxelize only the input entity profile.

  2 - Voxelize only voids/volumes of the input entity profile.

  3 - Voxelize both the input entity and voids/volumes.

Example

Create voxels of size 10.0 to include components with IDs 100 - 110 and exclude components with IDs 200 - 203

import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the components to be included
filter_in_components = hm.FilterByEnumeration(ent.Component, list(range(100, 111)))
in_component_collection = hm.Collection(model, filter_in_components)

# Creating a collection that contains the components to be excluded
filter_out_components = hm.FilterByEnumeration(ent.Component, list(range(200, 204)))
out_component_collection = hm.Collection(model, filter_out_components)

    collection=out_component_collection, mode=1
