A) Get the Deltares-software executables of iMOD
iMOD is open source software: since mid 2014 its source code can be downloaded from our SVN-repository. For those who prefer to use official Deltares-releases we are happy to announce:
|
The Deltares-executables of iMOD 4.2.1 are now available free of charge! ... including a new Parallel Krylov Solver Package allowing drastic reductions in run times ... To obtain the Deltares-executables of iMOD (for the request a 'Google form' is used; alternatively, please send an email to imod.support@deltares.nl directly) |
By submitting this form you are requesting for the use of the Deltares-software executables of iMOD. iMOD is Deltares-software; the source code of iMOD is also available as free open source software at oss.deltares.nl. You may use the Deltares-software executables of iMOD without any remuneration to be paid to Deltares if you accept the iMOD Software License Agreement (iMOD License) which is offered to you as a PDF-file, see http://oss.deltares.nl/web/iMOD/iMOD_Software_License_Agreement. Please go to the PDF-file of the iMOD License, read it and decide whether you want or do not want to accept the iMOD License. Without your acceptance of the iMOD License the use of the Deltares-executables of the iMOD-software is prohibited and illegal.
The iMOD software is distributed in the hope that it will be useful, but WITHOUT ANY GUARANTEE OR (IMPLIED) WARRANTY. Any use of the Deltares-executables of the iMOD-software is for your own risk. See the iMOD License for more details.
For more info, please contact: Stichting Deltares, P.O. Box 177, 2600 MH Delft, The Netherlands. Email: imod.support@deltares.nl.
After submitting this form you will receive download-specifications per email.
The Deltares-executables of iMOD are made available free of charge and does not include support, however, Deltares offers high level contracted support.

B3) Compile the iMOD source code
- To compile the iMOD Graphical User Interface please follow the steps as described in the file ReadMe.txt.
Some details from the ReadMe.txt file:
Software we used to compile the iMOD Graphical User Interface:
- Visual Studio 2008 Professional Edition, version 9.0.30729.1 SP (C) 2007 Microsoft Corporation
- Intel (R) Visual Fortran Intel(R) Compiler Professional for applications running on Intel(R) 64, Version 11.1.065
Necessary source code and libraries to compile the iMOD Graphical User Interface:
\BIN - should contain your binary after compiling the source;
\BMP - contains bitmaps for iMOD;
\CUR - contains cursors for iMOD;
\ICO - contains icons for iMOD;
\SRC - contains the fortran source code, subdivided in different folders;
\VS2008 - contains two Solution files for Visual Studio 2008 to compile iMOD.
\LIB - should contain libraries for third party software (not included in this repository)
\WINTERACTER - should contain the Winteracter 10.0 or higher library (www.winteracter.com)
\DELFTIO - should containt the Deltares IO library, needed to read in SOBEK files:
\NETCDF - should contain the NetCDF 3.0 library
\TUTORIALS - contains several tutorial data sets as describe on the iMOD Manual:
\TUT1_MAP_DISPLAY
\TUT2_DATA_MAP_OPER
\TUT3_MAP_ANALYSE
\TUT4_INITIAL_MODELING
\TUT5_SOLID_BUILDING
\TUT6_MODEL_SIMULATION
\TUT7_SCENARIO_TOOL

iMOD is partly based on the USGS MODFLOW2005 source code; for iMOD the USGS MODFLOW2005 source code has been expanded and extensively modified by Stichting Deltares. The resulting Deltares version of MODFLOW is also coupled with MetaSWAP (for simulating the vadose zone; Alterra, Wageningen University); the source code of MetaSWAP is also open source and should be downloaded here (the source code is not part of the iMOD svn-repository).
To compile the Deltares version of MODFLOW you need Intel(R) Visual Fortran Compiler XE 12.1.5.344. Please follow the steps as described in the file ReadMe.txt of the MODFLOW folder of the svn-repository.
Some details from the ReadMe.txt file:
- A Visual Studio 2010 solution is included (folder VS2010).
- For now, the code only runs on Windows.
- The main part of the iMOD utilities are located in the IMODUTL folder.
- The main program is called driver.f90, located in the DRIVER folder.
- This controller file calls a component based version of MODFLOW-2005, which can be seen as a low-level OpenMI implementation. Source code of MODFLOW is located in MF2005.
- In this folder, the file mf2005_comp.f shows the different phases in execution and the interface routines in case of a coupled code.
- This distributed code is prepared to couple MODFLOW with MetaSWAP, TRANSOL or MOZART. However, this code does not provide codes for MetaSWAP, TRANSOL or MOZART.
- For using iPEST: you should always pre-compile imod_pest.F90 with the IPEST flag. Note that in this release (iMOD 3.0) iPEST is not fully tested yet (in iMODFLOW 2.7 iPEST was fully tested).

C) Build your first iMOD groundwater model from scratch
The iMOD user manual contains several tutorials; tutorial 4 enables you to create your first groundwater flow model from scratch using iMOD. The necessary tutorial datasets are also made available via the iMOD svn-repository in the folder <iMOD-GUI tutorial dataset>; to download the tutorial data set please click here.
- Create the basic input files that are necessary to simulate a simple groundwater flow model;
- Enhance the model with an extraction well to compute the drawdown caused by the well;
- Simulate flowlines that describe the catchment area of the well
- Experiment with extraction rates to compute the maximum sustainable yield without extracting water from the sea.

D) Visualize your model output in 3D
Tutorial 5 of the iMOD user manual focusses on visualizing your model output (e.g. flowlines) and combine it with other geo-data of the subsurface such as borehole data. You can interactively edit and visualize the subsurface in 3D.

E) Exchange your experiences with other iMOD-users
- Make use of the iMOD-forum to get ideas from fellow-iMOD-users
- If your questions are not answered yet in the iMOD manuals or at the iMOD-forum
check out the support section to get high level support.
