TriAdvance

Applies to: Surfaces

Summary: Automatically meshes surface geometry with triangle elements.

Syntax:

Surface <range> Scheme TriAdvance

Discussion:

The triangle meshing scheme TriAdvance fills an arbitrary surface with triangle elements. It is an advancing front algorithm which allows holes in the surface and transitions between dissimilar element sizes. It can use a sizing function like the pave scheme if one is defined for the surface. Future development will add hard lines to this scheme's capabilities. You specify this scheme for a surface by giving the command:

To insure that coplanar (two-tris-sharing-three-node condition) or nearly coplanar tris at sharp geometric vertices are not generated using this scheme, a corrective edge-swap is automatically done.
