There are three boundary condition packages in this model: the CHD, MAW, and MVR packages. The CHD package is used to generate a uniform flow field from west to east. The MAW package is used to specify three injection wells and one withdrawal well. The MVR package is used to transfer the flow from the withdrawal well to two of the injection wells.
