Model.linedragnodestoformsurface

Model.linedragnodestoformsurface(sectionnodelist, draglinelist, dragnodelist, refplane_normal, refplane_base, using_default_vector)

Drags a list of nodes along a trimmed line 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 line-dragged surface for the automesher to use under the mesh without surface option.

Parameters:

• sectionnodelist (EntityList) – The list of node entities to be dragged.

• draglinelist (EntityList) – The list of line entities to drag along.

• dragnodelist (EntityList) – The list of two node entities which lie on the lines in the draglinelist which will be used to trim the line during surface creation.

• refplane_normal (hwTriple) – The hwTriple object defining the plane normal components. User can also supply a Python list of three doubles.

• refplane_base (hwTriple) – The hwTriple object defining the base point components of the plane. User can also supply a Python list of three doubles.

• using_default_vector (int) –

  Flag that defines the type normal vector. Valid options are:

  0 - Use plane normal vector

  1 - Use default normal vector

Example

Drag nodes with IDs 5 , 9 , and 10 along lines with IDs 2 and 1 , trimmed by nodes with IDs 29 and 30 , and use the given plane , create a surface but no elements

import hm
import hm.entities as ent

model = hm.Model()

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

sectionnode_list = [ent.Node(model, 5), ent.Node(model, 9), ent.Node(model, 10)]
dragline_list = [ent.Line(model, 2), ent.Line(model, 1)]
dragnode_list = [ent.Node(model, 29), ent.Node(model, 30)]
