MFI2005 A Data Input Program for the U.S. Geological Survey Modular Finite-Difference Ground-Water Model (MODFLOW-2005) Instructions for installation and execution are provided below. For assistance, enhancement requests, or bug reports contact Arlen Harbaugh via e-mail sent to harbaugh@usgs.gov. Availability of assistance for nonUSGS users is limited. MFI2005 runs only on personal computers using one of the Windows operating systems. Compilation of the code requires a Fortran 90 compiler and the Winteracter Subroutine Library (Interactive Software Services). The use of product and firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. INSTALLATION MFI2005 is distributed as a self-extracting distribution file: mfi2005v1_0.exe Execution of this distribution file will create a number of individual files. The distribution program will ask for an installation directory. It is recommended that you use C:\WRDAPP. The remaining instructions assume that C:\WRDAPP is the installation directory. The following directory structure will be created in C:\WRDAPP: |--MFI2005.1_0 |---bin ; compiled executable to run MFI2005 |---doc ; documentation files |---src ; source code It is recommended that no user files are kept in the MFI2005.1_0 directory structure. EXECUTION The easiest way to execute MFI2005 after it is installed is to make a desktop icon that runs file C:\WRDAPP\MFI2005.1_0\bin\mfi2005.exe. See your system administrator for information on how to do this. MFI2005 can also be executed within a command-prompt window. When running MFI2005 from a command-prompt window, it is convenient to make the MFI2005 program accessible without using a full pathname. Do this by including the C:\WRDAPP\MFI2005.1_0\BIN subdirectory in the PATH environment variable. The method for changing the PATH variable depends on the operating system being used. See your system administrator for directions for doing this. As an alternative, the MFI2005 executable file in the C:\WRDAPP\MFI2005.1_0\BIN subdirectory can be copied to a directory already included in the PATH environment variable. MFI2005 offers the capability to execute MODFLOW-2005 and UCODE_2005. These programs are invoked using Windows batch (.BAT) files, which are constructed by MFI2005. These batch files are executed in a separate command-prompt window. The batch file for running MODFLOW-2005 assumes that the MODFLOW-2005 runfile is named MF2005.exe, and this runfile is located in a directory in the PATH environment variable. If the MODFLOW-2005 runfile has a different name, or the runfile is located in a directory not in the PATH environment variable, the Pathnames command in the FILE menu of MFI2005 can be used to specify a full pathname for invoking MODFLOW-2005. Similarly, the command for running UCODE_2005 is assumed to be UCODE_2005, but this can be changed using the Pathnames command.
