Release notes for Five MODFLOW Utilities o Version 1.2.1 9/1/2011 This is a bug-fix release. MFBIN2RASTER (version 1.1.1) corrects the following bugs: Bug: Unusable results were produced when HDRY was specified as number less than or equal to zero and HNOFLO was greater than or equal to zero. Bug: Unusable results were produced when HNOFLO was specified equal to zero. Bug: Incorrect error message was written when 'modeldata.txt' file was not found. o Version 1.2.0 7/8/2009 This release adds minor new capabilities. CBC2RASTER (version 1.2.0) was modified to add support for extracting flow values recorded by the Drain (DRN), River (RIV), and General Head Boundary (GHB) Packages from a cell-by-cell flow file. To use the new capabilities, specify PID as "DRN", "RIV", or "GHB", respectively on the command line. For each of the newly supported packages, a raster text file is written for each layer for each time step that has nonzero flow values in the binary cell-by-cell flow file (similar to functioning when PID = 'WEL') o Version 1.1.0 6/17/2009 This release makes minor modifications to output. MFBIN2RASTER (version 1.1.0) was modified to minimize the amount of memory allocated during execution. Also, the output format for values read from the MODFLOW-generated head or drawdown file was changed to be able to represent a larger range of values by using exponents as required. o Version 1.0.1 3/27/2009 This release adds support for double-precision binary files. Double-precision executable files were added in the Bin directory for the CBC2RASTER, GRID2GRIDFLOW, and MFBIN2RASTER utilities. The double-precision versions are identified by file names that include "_dp". When a fully double-precision executable of MODFLOW-2000 or MODFLOW-2005 (generated during compilation by specifying a compiler option to promote all REAL variables to DOUBLE PRECISION) is used to generate the binary head, drawdown, and cell-by-cell flow files, the double-precision versions of the utilities that read these binary files must be used. o Version 1.0.0 10/15/2008 Initial release.
