E3SM Best Poster Award
JIGSAW Wins Best Poster Award
Out of 84 posters presented at the E3SM poster session at the Earth and Environmental System Modeling (EESM) PI Meeting in November 2018 at the Bolger Center in Maryland, the Best Poster Award went to the poster “JIGSAW: Multi-resolution Unstructured Mesh Generation for MPAS” by Darren Engwirda, Mark Petersen, Phillip J. Wolfram, Luke Van Roekel, Matt Hoffman, and Xylar Asay-Davis.
The authors beautifully present the generation of high-quality, multi-resolution unstructured grids for MPAS-O/SI. The new grid is a core requirement for upcoming E3SM science campaigns, allowing model resolution to be tailored to the physics and areas of interest associated with particular studies. The generation of such meshes is a non-trivial task! The authors describe recent work on the development and use of JIGSAW; a new unstructured mesh generation package designed to assemble complex two- and three-dimensional tessellations suitable for multi-resolution MPAS-O/SI configurations. A particular advantage of JIGSAW is its ability to rapidly generate very high-quality ‘generalised’ Delaunay triangulations and Voronoi-type tessellations optimised for high-resolution MPAS-O/SI studies. The authors present details of JIGSAW’s underlying mesh generation and optimisation algorithms, applicability to a range of global, regional and coastally-refined model configurations, and outline its integration into MPAS-O/SI workflows.
