changelog

PHAML's primary initial goal of the PHAML project was to produce a parallel version of MGGHAT. This has subsequently been extended to include additional capabilities. The target architecture is distributed memory multiprocessors, such as Beowolf-type PC clusters.

MGGHAT is a sequential program for the solution of 2D elliptic partial differential equations using low or high order finite elements, adaptive mesh refinement based on newest node bisection of triangles, and multigrid. All aspects of the method are based on the hierarchical basis functions.

Adaptive refinement, multigrid and parallel computing have each been shown to be effective means of vastly reducing the time required to solve differential equations. However, effectively combining all three techniques is not easy and is the subject of current research. PHAML is an attempt to solve this problem.
