Abstract

This study is aimed at developing 2D parallel adaptive mesh refinement algorithms for engineering applications such as penetration mechanics, manufacturing and combustion which use the finite element method for simulation. A new algorithmic approach, called piecewise adaptive mesh refinement for parallelization, is developed and implemented to run on a sequential machine. Performance of the new method is compared against a conventional advancing front technique proposed earlier. A parallel implementation model to run on a massively parallel computer is proposed and its expected efficiency is analyzed theoretically. Furthermore, some issues concerning parallelization and task partitioning are also discussed. In addition, a visualization tool is developed for pre- and post-processing of the finite element meshes that were generated. This tool runs under X-window environment and is used to display the triangular elements that form the mesh along with the physical values at the nodal points which are represented in color.
