*Program TriGrid : *

Delaunay triangulation using decomposed constructive geometry modeling for partial differential equations

# Program Abilities :

- Transform any two dimensional surface to a constructive solid geometry model CSG

- Decompose the CSG model into a set of minimal regions

- Using the decomposed CSG model to create a delaunay triangulation on the surface or at the entire outer domain

- 2D Euler rotation to rotate the surface inside a stationary frame before the domain grid initialization or to simply rotate the surface grid itself

- Reads geometry files of X and Y points describing the two dimensional surface

- Writes all the results to a text file
