Improved Voronoi Grid Generation

Support for unstructured grids (UGrids) began with GMS version 10. A variety of UGrids can be created using GMS. One type of UGrid is a Voronoi grid. A voronoi grid has certain desirable characteristics related to the computational scheme of MODFLOW-USG: MODFLOW-USG assumes that connected cells are perpendicularly bisected by a line connecting the centers of the cells. Recent enhancements to GMS 10.1 include a much faster Voronoi grid generator. An example model is shown below of a voronoi grid of the Biscayne Bay model area. This grid was generated in about 30 seconds on a core i7 3.4 GHz processor. The final grid has about 200,000 cells.

MODFLOW & More 2015 conference

Alan Lemon and Norm Jones had a great time at the MODFLOW and More 2015 Conference May 31 - June 3. We didn't seem to take any pictures of the conference, but here's one from the IGWMC Facebook page and if you look closely you can just make out the edge of the Aquaveo booth off to the right of the photo. :)
