Generating Multibillion Element Unstructured Meshes on Distributed Memory Parallel Machines

Table 1

Comparison of parallel mesh generation approaches.

Approach	Quality of modelling geometry
Mesh multiplication (uniform refinement) [13–15]	Worst
Mesh multiplication with geometry correction [16, 17]
Geometry partitioning [9] and PMSH
Fully parallel meshing [3, 5–8, 12]	Best
