3 New Features in GMS 10.1

GMS 10.1 adds the "Name File" dialog, which adds the following new capabilities:

  • Unsupported packages (packages that don't have an interface in GMS) can be included in the solution and edited in a text editor
  • Unsupported packages can be removed from the simulation
  • Unit numbers are no longer altered by GMS
  • Unit numbers can be set by the user

An example of the Name File dialog in use is shown below. In this example, a MODFLOW-CFP model was imported into GMS. Although GMS does not have an interface for the MODFLOW-CFP packages included in the model, those packages are still part of the simulation and are listed in the dialog. The input files for those packages can be edited from the dialog (using a text editor), or the packages can be removed from the simulation. But there is no need to remove the packages from the simulation because GMS 10.1 comes with a MODFLOW-CFP binary that can read the MODFLOW files that GMS writes. So this model can be run from GMS, and the solution, including the MODFLOW-CFP parts, can be displayed in GMS. This illustrates how GMS 10.1 includes better "support" for unsupported packages.

MODFLOW SWI2 package support in GMS 10.1

GMS 10.1 includes support for the MODFLOW SWI2 package. "The SWI2 Package allows three-dimensional vertically integrated variable-density groundwater flow and seawater intrusion in coastal multiaquifer systems to be simulated using MODFLOW-2005" (USGS) A tutorial and sample files are available with GMS 10.1. Below is an animation created in GMS of the movement of a freshwater \ saltwater boundary due to changes in head and well pumping rates.
