HYDRUS is fully operational under Windows Vistas; however, the user may encounter several small issues. For a list of these issues and the solutions to them, click here.

The HYDRUS software package is a major upgrade and extension of the HYDRUS-2D/MESHGEN-2D software package (originally developed and released by U.S. Salinity Laboratory, International Groundwater Modeling Center, and PC-Progress). HYDRUS has a completely new graphical environment for both two- and three-dimensional applications and should provide users with much more comfort than the original HYDRUS-2D software. This new software is released under the name HYDRUS and its different versions (called below levels) will encompass both two- and three-dimensional applications.

HYDRUS provides users with the flexibility to purchase only that segment of the software that they need. Table 1 contains description and pricing of five available HYDRUS Levels and their brief description. Users can thus select software only for two-dimensional or for both two- and three-dimensional applications, or for simpler or complex geometries. Users are able to upgrade from any lower HYDRUS Level to higher Levels, as well as from older software (HYDRUS-2D or HYDRUS-2D/MESHGEN-2D) to any new HYDRUS Level. Multiple user licenses for up to 20 PCs are priced at the double price of a single license. The regular updates will be provided free of charge for the next two years).

New Features

Graphical User Interface:

• Completely new GUI based on Hi-End 3D graphics libraries.
• MDI architecture - multiple projects and multiple views can be opened at the same time in the Hydrus main window.
• New organization of geometric objects. All objects are numbered and summarized in an organized system based on the principle of "parents and children". Object indexing enables easy control of object definition.
• Navigator window with an object explorer and a tree of display options.
• Many new functions improving the user-friendliness, such as drag-and-drop, context sensitive pop-up menus after clicking on objects, and selection and editing of multiple objects in the same dialog window.
• Improved interactive tools for graphical input. Users can combine graphical input with numerical input of parameters on the Edit bar. It is also possible to change the view (zoom/scroll/rotate scene) without interrupting the current tool.
• Sections, objects similar to AutoCAD layers, can be used to simplify work with very complex models and FE-meshes.
• Cross-Sections and Mesh-Lines for charts can be saved with the project data.
• Display Options - all colors, line styles, fonts and other parameters of graphical objects can be customized.
• Extended print options.
• Extended information in the Project Manager (including project preview).
• Actual and cumulative fluxes across internal meshlines (lines connecting sequential FE-nodes).
• Many additional improvements
  

Calculations:

• Water flow in a dual-porosity system allowing for preferential flow in fractures or macropores while storing water in the matrix (Simunek et al., 2003).
• Root water uptake with compensation.
• Spatial root distribution functions of Vrugt et al. (2001, 2002).
• Soil hydraulic property models of Kosugi (1995) and Durner (1994).
• Transport of viruses, colloids, and/or bacteria using an attachment/detachment model, filtration theory, and blocking functions (Schijven and Simunek, 2002; Bradford et al., 2003, 2004, 2005).
• Constructed wetland module (only in 2D) (Langergraber and Simunek, 2005).
• Hysteresis model of Lenhard et al. (1991) and Lenhard and Parker (1992) to eliminate pumping by keeping track of historical reversal points.
• New print management (printing at regular time intervals or after constant number of time steps).
• Dynamic, system-dependent boundary conditions (e.g., switching between pressure heads, seepage face, zero flux or atmospheric boundary depending on the position of the water level).
• Flowing particles in two-dimensional applications.
  

System Requirements

Intel Pentium or higher processor, 16 Mb RAM, hard disk with at least 20 Mb free disk space, VGA graphics (High Color recommended), MS Windows 95, 98, NT, 2000, XP

License Information

The HYDRUS license is protected by a software lock that is based on information about your hardware. Without activation HYDRUS works as a demo version - you can run it but you will not be able to run calculation and save your data.  

How to activate HYDRUS:

• Before activation we recommend you to download the latest HYDRUS version.

• After installation of the HYDRUS on your computer go to the "Hydrus Activation" dialog and generate authorization codes specific for your computer. Send us these codes via e-mail.

• We will generate activation codes according to the license type that you have purchased and send you these codes back. 

• After entering these codes your HYDRUS will be activated.

HYDRUS reinstallation or moving to another computer:

• With a "single user" license you are eligible to install and use HYDRUS on two computers (for example a computer in your office and your notebook).      

• If you reinstall HYDRUS on an activated computer or if you install a newer HYDRUS version then your previous authorization will remain active. However, HYDRUS must be installed on the same hard drive (not necessarily to the same directory) as the previous installation.

• Before any hardware changes or reinstallation of Windows OS or if you want to move your license to another computer you should deactivate HYDRUS on the original computer. Go to the Hydrus Activation dialog
  
  
  and press button "Deactivate HYDRUS".
  
  
  Click Yes.
  
  
  Save DeactH3D.lf in the folder you want to save.
  
  
  
  Send us a copy of the file that will be created during the deactivation. After you finish HYDRUS installation on the new computer you will have to activate it in the same way as described above.

Discounts for the educational use:

• We do not offer any discounts for the academic/educational use.
