Supported Packages and Engines
When you purchase Visual MODFLOW Flex you will recieve two separate standalone interfaces: Visual MODFLOW Classic Interface and Visual MODFLOW Flex Interface. The combination of both interfaces offer a complimentary set of tools that you can use to build and run your models.
Note: Items marked with an * are only available from within the accompanying Visual MODFLOW Classic Interface.
MODFLOW Engines
