Starting at GMS 8.0 there is a free version of GMS called "GMS Community Edition". This version includes the MODFLOW and 3D Grid components and thus allows grid-based creation and editing of MODFLOW simulations. Existing simulations can be imported and edited as normal. There are size limits in this free version: grids can be no bigger than 5,000 cells and MODFLOW is limited to 3 stress periods. You can still import models bigger than this but then printing and saving are disabled. Otherwise, printing and saving work as normal. Also, once a model exceeds the limits a watermark will appear in the graphics window.
We hope this free version will allow more users to easily begin discovering GMS.
