Model.surfacetorusfromthreepoints

Model.surfacetorusfromthreepoints(major_center, minor_center, minor_radius)

Creates a torus which passes through the three specified nodes, and optionally, prepares it for immediate use in the automesher. It also can identify a toroidal region for the automesher to use with the mesh without surface option.

Parameters:

• major_center (Entity) – The node entity specifying the major center of the torus.

• minor_center (Entity) – The node entity specifying the minor center of the torus.

• minor_radius (Entity) – The node entity through which the minor revolution will pass.

Example

Create a torus which has the major center at node with ID 1 , the minor center at node with ID 5 , and the minor radius at node with ID 13 , and not create any elements

import hm
import hm.entities as ent

model = hm.Model()

model.surfacemode(mode=4)

model.surfacetorusfromthreepoints(
    major_center=ent.Node(model, 1),
    minor_center=ent.Node(model, 5),
    minor_radius=ent.Node(model, 13),
)

Note

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