Model.updatefeatures

Model.updatefeatures(flag)

This function specifies for element remesh with feature edged when 1D elements selected as features are also refined. This function implies a function that performs re-meshing/meshing by elements with redo option selected is to follow.

Parameters:

flag (int) –

0 - 1D elements selected as feature edges are not refined.

1 - 1D elements selected as feature edges are refined. New 1D elements connected to a new mesh are created.

Example

Remeshe elements 1 - 40 with element size 10 , use 1D elements with IDs 100 - 110 as feature edges , and create along these feature edges new 1D elements with the same properties connected to created mesh

import hm
import hm.entities as ent

model = hm.Model()

# Creating the collection that contains the elements with IDs 1-100 that will be used as feature edges.
filter_remesh_elements = hm.FilterByEnumeration(ent.Element, list(range(1, 101)))
collection_remesh_elements = hm.Collection(model, filter_remesh_elements)

# Defining the collection of elements as fearure edges before remeshing.
model.elementsaddelemsfixed(collection=collection_remesh_elements)

# The elements with IDs 1-100 selected as feature edges are refined. New 1D elements connected to a new mesh will be created.
model.updatefeatures(flag=1)

# Specifying the mode for defining and using feature edges for element-based re-meshing.
model.setusefeatures(mode=1)

# Creating the collection of the remeshing elements with IDs 1-40.
filter_remeshing_elements = hm.FilterByEnumeration(ent.Element, list(range(1, 41)))
collection_remeshing_elements = hm.Collection(model, filter_remeshing_elements)

# Remeshing the elements with IDs 1-40.
