Surface Meshing: Yes

Tri/Tet Method: Delaunay, Advancing Front

We have meshers which use the Advancing Front and the Delaunay methods to generate tri's in 2D and on surfaces, as well as a Delaunay tet mesher. Advancing Front tet mesher is coming.

Quad/Hex Method: Advancing Front, Grid Based

Overlay

For generating quad elements in 2d and on surfaces, we offer meshers using the Advancing Front and overlay methods. Our hex mesher utilizes a grid-based method with coarsening.

Element Sizing Method: Manual

The 2D & surface Advancing Front and Delaunay (quad & tri) meshers use pre-defined divisions on the boundary curves to define the element sizes. These divisions may be defined manually or automatically according to average length, # divisions / curve, or error (curvature-based).

The 2D overlay mesher bases element size on # elements desired in the u and v directions (with bias factors).

The 3D (Delaunay) tet mesher conforms its mesh to an input tri surface mesh and bases the tet element size on this input.

The 3D hex mesher uses global element size specifications for each direction.
