MT3DMS Problem 10, Two Domains
The purpose of this example is to demonstrate the model setup for a coupled GWF-GWT simulation with submodels. It replicates the three-dimensional field case study model from the 1999 MT3DMS report. The results are checked for equivalence with the MODFLOW 6 GWT solutions as produced by the example ‘MT3DMS problem 10’.
Initial setup
Import dependencies, define the example name and workspace, and read settings from environment variables.

Define parameters
Define model units, parameters and other settings. Note: the (relative) dimensions of the two models are not configurable.
