For those of you attending the MODFLOW Conference at Colorado School of Mines in a couple of weeks, I will be demonstrating the use of nested grids in a new version of MODFLOW called MODFLOW-USGs, developed by Sorab Panday. We use the term nested grid to refer to a refinement to the finite-difference grid where the grid lines do not extend beyond the refined area, as shown above. This greatly reduces the number of grid cells. It is similar in concept to MODFLOW2005-LGR (Local Grid Refinement), except that MODFLOW-USGs is one simulation rather than two. Chris Langevin and Sorab Panday will both be presenting papers on this new style of MODFLOW modeling and on MODFLOW-USGs specifically.
Our demonstration will take place on Monday evening, June 6th, from 5:30 to 7:30 in the Green Center, Friedhoff Hall. Please stop by and I can show you more. I will also be posting a lot more about this new MODFLOW version in coming blog posts.
Hope to see you there.
