Model.hmmeshspline

Model.hmmeshspline(quads)

Within the automeshing module, generates quad or tria elements using a flexible surfaceless algorithm. Can only be used together with model.surfacemode(mode=3) and one of the Model.splinesurface() function.

Parameters:

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

Example

Generate elements with densities of 10 , 11 , 10 , and 10 along the given edges

import hm
import hm.entities as ent

model = hm.Model()

model.surfacemode(mode=3)
line1 = ent.Line(model, 1)
line2 = ent.Line(model, 2)
line3 = ent.Line(model, 7)
line4 = ent.Line(model, 8)
