Model.hmmeshlinedrag

Model.hmmeshlinedrag(quads)

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

Parameters:

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

Example

Drag the given nodes along lines with IDs 2 and 1 , trimmed by nodes with IDs 29 and 30 , and use the given plane , create 45 elements

import hm
import hm.entities as ent

model = hm.Model()

model.surfacemode(mode=3)
node1 = ent.Node(model, 5)
node2 = ent.Node(model, 9)
node3 = ent.Node(model, 1)
node4 = ent.Node(model, 15)
node5 = ent.Node(model, 18)
node6 = ent.Node(model, 39)
