Model.linearmesh#

Model.linearmesh(quads)#

Within the automeshing module, generates quad or tria elements using a flexible surfaceless algorithm that approximates a ruled surface. Can only be used together with Model.surfacemode() where mode=3 and one of the Model.linearsurfacebetweenlines() or Model.linearsurfacebetweennodes() or Model.linearsurfacebetweennodesandline(). functions.

Parameters:

quads (int) – If nonzero, specifies that the created elements should be quads.

Example#

Identify a region in the shape of a ruled surface and sends it into the automesher to create quad elements and store the elements to the HyperMesh database#
import hm
import hm.entities as ent

model = hm.Model()

'''

Indentifying a region in the shape of a ruled surface using
the model.surfacemode(mode=3), the model.linearsurfacebetweennodes()
and sends it into the automesher via the model.set_meshedgeparams()
to create quad elements via model.linearmesh(quads=1). The
model.storemeshtodatabase() stores the elements in Hypermesh database.
