We have had some requests over the last couple of years for a limited version of GV that can be given to clients or others who just want to look at the model for review purposes. We have now created a 'Viewer Version' of Groundwater Vistas. When you run Groundwater Vistas without a hardware lock or code, it runs as a student version. The student version is limited to 50 rows, 50 columns, and 4 layers. If you try to open a Groundwater Vistas model larger than the student version GV reverts to 'Viewer' mode. In this mode, you can look at everything in the model and you can print. You cannot run models or make changes to the model, however. Thus, your client can simply download GV from our web site and install it to review your models.
