Appendix 1—Data Input Instructions for Multi-Node Well (MNW2) Package 45 Appendix 1—Data Input Instructions for Multi-Node Well (MNW2) Package MODFLOW Name File The MNW2 Package is activated by including a record in the MODFLOW name file using the file type (Ftype) “MNW2” to indicate that relevant calculations are to be made in the model and to specify the related input data file. The user can optionally specify that information calculated for specific multi-node wells are to be written to separate output files by including a record in the MODFLOW name file using the file type (Ftype) “MNWI” that specifies the relevant input data file giving selected well locations. The MNW2 and MNWI Packages are compatible with MODFLOW–2000 (Harbaugh and others, 2000) and MODFLOW–2005 (Harbaugh, 2005) and with compatible versions of the ground-water transport process, but not with earlier versions of MODFLOW. MNW2 Package Input Data The MNW2 input file consists of input items (datasets) numbered from 0 through 4, each consisting of one or more records, as described in detail below. These data are used to specify information about the locations, flows, physical and hydraulic properties of the wells, and possibly solute concentrations, as well as specifying certain output control options. In the following description, input parameters are indicated as being optional by their enclosure in curly brackets. All input variables are read using free formats. In free format, variables are separated by one or more spaces or by a comma and optionally one or more spaces. Thus, in free format, a blank field cannot be used to s...
