*surfacetorus

Creates a full or partial torus, 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.

Description

Creates a full or partial torus, 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.

Inputs

center
A node specifying the major center of the torus.
major vector
A node specifying the major axis of the torus.
normal vector
A node specifying the normal axis of the torus.
minor radius
The minor radius of the torus.
major radius
The major radius of the torus.
major start angle
Angle at which the major radius of the torus starts (0.0 to < major end angle).
major end angle
Angle at which the major radius of the torus ends (> major start angle to 360.0).
minor start angle
Angle at which the minor radius of the torus starts (0.0 to < minor end angle).
minor end angle
Angle at which the minor radius of the torus ends (> minor start angle to 360.0).

Example

This example creates the bottom half of a torus with center at node 1, normal vector at node 12, major vector at node 4, and a major radius of 10 and a minor radius of 2.5, but does not continue to the automesher for element creation:

*surfacemode(4)
*surfacetorus(1,12,4,2.5,10.0,0.0000,360.0000,180.0000,
   360.0000)

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

Errors

None.
