Model.solidmap_equivalence#

Model.solidmap_equivalence(tolerance, find_faces)#

It equivalences two sets of nodes, based on a given tolerance and, optionally, does a special find_faces operation. This function is used by the solid mapping algorithm.

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 Model.solid_facesfind(). This step is useful for continuing with the next solid map operation.

Parameters:

  • tolerance (double) – The tolerance to use for finding nodes in the equivalence operation.

  • find_faces (int) –

    A flag indicating whether to perform the special faces operation. Valid values are:

    0 - Do not perform the find.

    1 - Perform the find.

Example#

Equivalence the solidmap and “^faces” nodes use a tolerance of 0.01 and find the new faces#
import hm
import hm.entities as ent

model = hm.Model()

model.solidmap_equivalence(tolerance=0.01, find_faces=1)
