Abstract
A strategy for the parallel generation of 3D tetrahedral unstructured meshes is proposed based on the extension of the 2D algorithms presented by Okusanya et al. These are based on a sequence of point insertion and load balancing cycles. Points are inserted concurrently within each subdomain and dynamic load-balancing is incorporated to ensure an even work distribution during the generation process. The inter-processor boundaries are allowed to move to accommodate element migration between subdomains.
