Model.solidmap_equivalence2#

Model.solidmap_equivalence2(collection, tolerance, find_faces)#

Equivalences two sets of nodes, based on a given tolerance and, optionally, does a special find_faces operation.

For equivalencing, the first set of nodes are from the elements in the solidmap and ^faces components. The second set of nodes consists of all of the nodes not included in the first set but falling within the specified tolerance.

For the find_faces operation, 3D elements in the solidmap component are used to find the faces. All pre-existing faces are filtered out and the remaining faces are added to the ^faces component. See the function . This step is useful for continuing with the next solid map operation.

Parameters:

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

  • tolerance (double) – The value of tolerance used for finding nodes during the equivalencing operation.

  • find_faces (int) –

    The flag indicating whether to perform the special faces operation.

    0 - Do not perform the find.

    1 - Perform the find.

Example#

Equivalence the displayed elements in collection with “^faces” nodes use a tolerance of 0.1 and find the new faces#
import hm
import hm.entities as ent

model = hm.Model()

model.solidmap_equivalence2(
    collection=hm.CollectionByDisplayed(model, ent.Element),
    tolerance=0.1,
    find_faces=1,
)
