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
