Elements: Triangle

Surface Meshing: No

Tri/Tet Method: Delaunay

Generally Delaunay, but ACE/gredit is mostly a wrapper around triangulation routines produced elsewhere. The latest is Schewchuck's Triangle (http://www.cs.cmu.edu/~quake/triangle.html). Originally, the implementation of Steve Fortune's sweepline algorithm as found on Netlib was used for triangulation.

Element Sizing Method:

Points to be triangulated are generated in the domain based on numerical criteria such as the Courant number or the dimensionless wavelength.

Other Features:

Comments:

ACE/gredit supports generation of grids of triangles only, but will display quadrilateral elements.
