Availability: Public Domain

Customer Support: Yes

Pricing: None, the binaries are free

Platform: Windows, UNIX (SGI, Sun, Linux ELF and others)

DOS

Input: Native

Boundary points. The points that describe the polygonal region.

Engineering Discipline: CFD

Elements: Quadrilateral

Surface Meshing: No

Quad/Hex Method: Structured Grid Generation

Discrete Methods: The grid is obtained by a optimize process using functionals that measure geometric properties (see http://www.mathmoo.unam.mx/unamalla/problem.html)

Element Sizing Method:

Manual and Automatic based on global feature size and others geometrics properties.

Other Features: Refinement

Uniform refinement, solve some Elliptic PDE using difference-finite scemes.

Comments:

This system uses the new adaptive functionals to solve the grid generation problem over very irregular regions. The system works over polygonal regions without holes and regions with one hole using an aditional segment inter boundaries.
