Starting in GMS 10.5, GMS can create a basic MDOFLOW 6 project. Building a MODFLOW 6 project in GMS makes use of a simulation workflow. The new simulation workflow builds the MODFLOW 6 using a different procedure than previously used in GMS. This process allows for multiple MODFLOW 6 simulations to be contained in the same project file.
Before building a MODFLOW 6 simulation, a 3D UGrid of the project area is required. While the project can contain multiple UGrids, only one UGrid can be attached to each MODFLOW 6 simulation.
To create a MODFLOW simulation:
When the simulation has been initially created, the select UGrid will be linked to the simulation and the simulation packages will appear in the Project Explorer. Certain packages will always be included in the simulation. These include the TDIS and IMS packages along with the GWF model which includes the DIS, NPF, IC, and OC packages. Optional packages, if any were selected, will appear under the GWF model.
Double-clicking on any of the packages listed in the Project Explorer will bring up the package dialog for that package.
In the Project Explorer, right-clicking on MODFLOW 6 simulation brings up a menu with several commands. Some of these commands are common to other Project Explorer right-click menus. Others are unique to the simulation right-click menus. Some of these unique commands are:
Starting in GMS 10.4, GMS can export MODFLOW files for use with MODFLOW 6. This version of MODFLOW contains a new object-oriented program and underlying framework for supporting multiple types of models within the same simulation.
The process for doing this is similar to that of saving native text files. In the MODFLOW Global/Basic Package dialog, there is an option to Save MODFLOW 6 copy. When this option is selected, MODFLOW 6 files will be generated when running MODFLOW from GMS.
The MODFLOW 6 export option does not function with projects that are incompatible with MODFLOW 6. Projects with unsupported features or parameters will not be successfully exported.
Not all MODFLOW packages are supported in MODFLOW 6. The following table shows the correlation between MODFLOW 6 packages and packages from previous versions of MODFLOW.

The files generated for MDOFLOW6 will appear similar to those created for other versions of MODFLOW. The *.mfn.log file will contain notes about the export and mention any items that could not be exported for MODFLOW 6.
