-------------------------------------------------------------------------------------- February 13, 2015 GFLOW version 2.2.2 -------------------------------------------------------------------------------------- GFLOW installation instructions and upgrade information: GFLOW version 2.2.2 (dated February 1, 2016 on the splash screen) * Microsoft Windows XP or later. * 500 MB of RAM or more * Microsoft Internet Explorer version 4.01 Service Pack 2 or later. ---------------------------- To install GFLOW proceed as follows: ----------------------------------------- 1) NOTE: Remove any older version of GFLOW, including the GFLOW folder and all its contents under "C:\Program Files" and make sure you run no other applications while installing GFLOW version 2.2.2! 2) Double click GFLOW_v222_setup.exe and follow the instructions on the screen. I recommend you use the default installation path "c:\Program Files\GFLOW" 3) NOTE: You may encounter some Warnings about files that the install program likes to replace, but which are "protected by the operating system". GFLOW will most likely run fine with the current operating system configuration, hence click OK and proceed with the installation. If GFLOW fails to run properly, one or more of the warnings indicate the need to update the operating system. The GFLOW install program cannot do this (Microsoft policy), you must go to the Microsoft website to download the necessary operating system upgrade. A typical GFLOW run-time error message that indicates missing or incorrectly installed operating system components is: "Object variable or With block variable not set (error number 91)" 4) After installation of GFLOW, you will find GFLOW on the Start>Programs menu. Additionally, a short cut is placed on the desktop. 5) Version 2.2.2 is equiped with a new HTML based context sensitive Help system that requires no MS downloads (as was needed with earlier versions). 6) If you did not yet run a licensed "Professional Version" of GFLOW on your computer the program will come up as the "Educational Version". The educational version has several features disabled, see the License Agreement and the "Overview of Features in GFLOW.pdf" document. Commercial use of the Eucational Version is strictly prohibited, see the "GFLOW Licence Agreement.rtf" document. 7) If you did run a licensed professional version before this install procedure, the program will automatically come up as a professional version. You do not have to register again. 8) If you want to register your program to obtain the professional version, go to the web site www.haitjema.com for pricing and ordering information. You may Email me at sales@haitjema.com or call me at 812 336 2464. 9) Test the program by opening the file "example.gfl" in the folder “c:Documents and Settings\\My Documents\GFLOW projects\example" If you are new to GFLOW, I recommend that you go over the Tutorial for an introduction to the program. NOTE: Upon opening “example.gfl” or any other project file delivered with this program you may receive a message stating: “Your Project File and your Intermediate Model Files are not set in the same place! This may cause problems.Would you like to set your Intermediate Model File path to your project path?” Simply click on Yes to correct this. The message is due to the fact that the project file may have been opened on another drive (with another drive letter) than the one it is on currently. 10) IMPORTANT: If you have been a GFLOW user already and created GFLOW projects you should move these projects (organized in your project folders) to the Document or My Document folder in the PERSONALDATA path. For instance, on a Windows XP macine this is \Documents and Settings\\my documents\GFLOW projects. After GFLOW installation you may seacrh for the folder "GFLOW projects" to find the proper path on your machine. —————————————————————— Important document —————————————————— I highly recommend that you read the document “Overview of features in GFLOW.pdf” which offers a good introduction to GFLOW’s versatile modeling tools. ------------------------- Important information: ------------------------------------------ 1) Warning for users outside the USA: The GFLOW solver is a FORTRAN code which only recognizes the period as the decimal point. For proper operation of GFLOW the Windows operating system must be set to the English (United States) locale. To do so proceed as follows: Go to: Start Menu>Settings>Control Panel>Regional Options under "Your locale (location)" select: English (United States) 2) When using basemaps in GFLOW avoid large detailed maps. They are useful for presentation graphics, but unnecessary as basemaps for groundwater modeling purposes. Large detailed maps will result in very slow redraws and often obscure the analytic element layout and graphical modeling results (contours, pathless, etc.). To simplify your basemap in GFLOW, break your original map up in "layers" and create separate files for each layer. This allows you to limit the number of layers to be displayed by selecting or deselecting files (map layers) on the View>Base Map menu. For presentation purposes export model results to a CAD or GIS program for mark-ups and combination with more detailed maps. 4) Before using the MODFLOW extract feature consult the GFLOW manual (from the program or as pdf) for limitations and proper option settings. The user is responsible for checking that the MODFLOW solution is the same as the GFLOW solution!! Only after verifying the integrity of the MODFLOW extract process should you undertake to make modifications to the model in a MODFLOW GUI. NOTE: Not all MODFLOW GUIs are equally good at importing MODFLOW files - the extract feature is known to work correctly with GWVista from Environmental Solutions Incorporated (ESI). 5) Always check the accuracy with which boundary conditions are met by going to Model>View Model Run Files>Runtime Message File. The first line in that file indicates the last update of the solver (of importance when looking for patches or upgrades). Below that follow solution progress reports for the various iterations. Boundary conditions, in general, should be met within 1%. Note: the default GUI setting is to automatically display this file after each solution. 6) Visually inspect the contour plots for irregularities. Jumps in the head can only occur at no-flow or resistance barriers, or when the groundwater elevations are drawn down to the edge of a domain with a jump in the base elevation. Jumps in the head show up as bundled up contours. Always be on the alert for unreasonable solutions. 7) When tracing streamlines in a very large model window, it may be necessary to override the default stepsize. The default stepsize depends on the window size. Too large a step size may lead to hooky and inaccurate pathlines. To reduce the stepsize go to Model>Settings>Tracing. 8) Start simple (with a small simple model) and then gradually add detail and complexity as needed. Frequently solve when adding features or making changes. 9) Regularly visit www.haitjema.com to check for new releases, program upgrades, and new documentation. 10) You may save the documents on the website by opening them in Adobe Acrobat Reader (click on the document name) and then save them on your hard drive. I wish you much success Sincerely, Henk Haitjema (president Haitjema Software)
