A TWO-DIMENSIONAL PARALLEL QUADTREE FINITE ELEMENT MESH GENERATOR
A. J. BARRAGÁN, Jeff S. Reeve · 2000
INTRODUCTION Finite element mesh generation has come a long way since its beginnings, having evolved from being manual procedures for feeding data to finite element programs, to becoming integral part of the solution process. Nowadays, mesh generation is also linked to sophisticated methods for representing complex three-dimensional geometries in an attempt to wholly automate the design-analysis process. Recently, the availability of high performance computing (HPC) has opened the door to the use of more refined meshes. This may allow for more accurate geometric representations in some cases, and more precise iterative methods in others. HPC has become more available for two main reasons: On one side, the increasing ratio performance/cost in hardware, and in the other, the increased availability of programming tools such as the Message Passing Interface Library (MPI), that have lightened the task of writing parallel programs for different computing environments. 2 REL
