Research Note Abstract
We present details on the advancing front surface meshing algorithm that has been developed to provide surface meshing capabilities for the mesh generation component (MeshKit) that is part of the SIGMA toolkit. The open-source implementation has been abstracted to work with geometry and mesh data-structure agnostic interfaces, thereby providing an extensible and efficient tool for performing parallel mesh generation on complex geometries. The algorithm can be readily adapted to utilize either on-node or inter-node parallelism by utilizing the graph-based architecture in MeshKit and can be easily extended to use different templates for advancing the front or different two-dimensional approximations to the surface geometry. Preliminary results for several test problems are shown and performance of the algorithm in comparison to NETGEN is presented.
