Starting at GMS version 10.0, GMS supports MODFLOW-USG. MODFLOW-USG is a version of MODFLOW based on finite volume calculations, thus allowing for many different types of grid cells. This allows the model grid to more accurately match the model domain and be more efficiently refined in areas where more accuracy is desired.
MODFLOW-USG models are built using unstructured grids, or UGrids, which are a new (as of GMS 10.0) type of geometric object that can handle the wide variety of cell types supported by MODFLOW-USG.
Choosing MODFLOW Version
Only MODFLOW-USG is supported when using unstructured grids. MODLFOW-USG can also be used for a model using a 3D grid. Choosing to use MODFLOW-USG is done in the MODFLOW Global Options Dialog. With a 3D grid at any time you can switch from one modflow version to another.
