These options are now saved in the MODFLOW super file and are therefore portable. Capture Zone Analysis dialog rearranged CCF files are read more generically and data in unsupported packages is imported MODFLOW writes out the final array values of input arrays that use parameters. For example, if HK is being estimated with pilot points then part of the MODFLOW solution in the Project Explorer will be an HK data set with the final array values. Stochastic analysis of MODFLOW solutions now includes calculating the min, max, mean, and standard deviation of the MODFLOW parameter arrays that are part of the MODFLOW solutions. PEST Push-of-a-button support for PEST null space Monte Carlo. Generate multiple calibrated models for uncertainty analysis.

Images Online dynamic images Choose from several online images, maps, and elevation data to include as background images. The images update automatically while panning and zooming. Create a static image from the dynamic image to save with the project Raster/DEM import and interpolation Support for large DEMs (multiple formats) and GeoTIFFs containing elevation data (such as those created from USGS NED data online maps). These can be imported and interpolated directly to TINs, 2D scatter points, 2D grids and 2D meshes without the need to convert to 2D scatter points. DEMs can be exported in multiple formats. Images moved to be under GIS layers. Images folder no longer exists. Horizons to Solids using rasters Project On-The-Fly Individual objects can now define their own projections and get projected on-the-fly to the display projection. This is how images have always worked and now it's available for all GMS objects. Projection files saved and imported A projection file (.prj) is saved whenever a geometric object (TIN, mesh, borhole etc) is exported to a file. GMS will also look for a corresponding .prj file whenever a file is opened if the current projection is local. If one is found, it is opened and the current projection is set to the information in the file. This is a precursor to full project-on-the-fly which is in the works. Current projection displayed at the bottom of the graphics window Latitude/longitude displayed at the bottom of the graphics window CAD file changes Support for having multiple CAD files added to the project CAD files are no longer saved when the project is saved CAD properties dialog Tutorials MNW2 tutorial for non-vertical wells and pump capacity MODFLOW Subsidence Package MODFLOW STR Package Split MODFLOW conceptual model tutorial into two Null Space Monte Carlo Online Maps Rasters Horizons with Rasters Miscellaneous Measure tool The static tool palette gets a new tool for quickly and easily measuring distances.
