Abstract
This research note reports the design and implementation of a novel, robust parallel algorithm using GPUs (graphics processing units) to generate triangular meshes over complex, unstructured domains or with an unsuitable initial discretization. Algorithms have been implemented using the CUDA architecture and compared with their serial counterparts for several benchmark case studies. Results demonstrate that the GPU-based parallel algorithms developed are several orders of magnitude faster than their serial equivalents.
