Model.dragnodestoformsurface

Model.dragnodestoformsurface(entitylist, direction_vector, distance, solid_stitch=0)

Drags a list of nodes to create a surface, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of a dragged surface for the automesher to use under the mesh without surface option.

Parameters:

• entitylist (EntityList) – The nodes to be dragged.

• direction_vector (hwTriple) – The direction vector to drag the nodes.

• distance (double) – The distance to drag the nodes.

• solid_stitch (int) –

  0 - Created surface will not be stitched to a solid.

  1 - Created surface will be stitched to a solid.

Example

Drag the nodes with IDs 5, 6, 7, 10, 11 and 12, -100.0 units in the direction of the y-axis, create a surface but no elements

import hm
import hm.entities as ent

model = hm.Model()

# The model.surfacemode(mode=4) tells HyperMesh not to pass the information on to the automesher for element creation.
model.surfacemode(mode=4)

nodelist = [ ent.Node(model,id) for id in [5,6,7,10,11,12] ]

model.dragnodestoformsurface(
    entitylist=nodelist,
    direction_vector=[0.0, 1.0, 0.0],
    distance=-100.0,
)
