Within this new framework, a regional-scale groundwater model may be coupled with multiple local-scale groundwater models. Transfer of information between models is isolated to exchange objects, which allow models to be developed and used independently of one another. These models can be independent of one another with no interaction, they can exchange information with one another, or they can be tightly coupled at the matrix level by adding them to the same numerical solution. In the new design, any number of models can be included in a simulation. This version of MODFLOW is labeled with a "6" because it is the sixth core version of MODFLOW to be released by the USGS (previous core versions were released in 1984, 1988, 1996, 2000, and 2005). MODFLOW 6 is an object-oriented program and framework developed to provide a platform for supporting multiple models and multiple types of models within the same simulation. This type of layered grid can be represented using the Discretization by Vertices (DISV) Package in MODFLOW 6. This figure shows a triangular grid in which the size of the triangular cells is reduced in areas with relatively large hydraulic gradients, such as around the shoreline of a lake, near pumping wells, and along a stream.
