Th. van Genuchten, New features of the version 3 of the HYDRUS (2D/3D) computer software package, Journal of Hydrology and Hydromechanics, a Thematic Issue "HYDRUS Applications to Subsurface Flow and Contaminant Transport Problems",66(2), doi: 10.1515/johh-2017-0050, 2018.
History of changes:
==================================
Version 3.03.0300 – 15.12.2020
==================================
New Features and improvements:
- Inverse Solution was enabled for 3D projects
- A dynamic rooting system (root growth) was included also into the UnsatChem and Wetland modules.
- Line Probes - allows you to draw a graph of any quantity along any curve defined by a polyline.
- Point Probes - allows you to display values of any quantity at points anywhere in the transport domain (independent of FE nodes).
- The clipping of the 3D model and the FE-mesh has been extended with a new option, the "Clipper-Box" tool.
- Improvements of the functionality and performance of 3D graphics: Drawing of objects in transparent mode, control of the center of rotation when rotating a scene, speed up graphics when drawing complex models and large FE-meshes.
- New options for manipulation and graphical display of background layers and bitmaps.
Fixed Errors:
- Root growth in 2D is active when horizontal root growth is inactive.
- The HP2 calculation module could fail to start under certain circumstances
- Error in SlopeCube2D when editing boundary conditions on mesh
- Error when generating tetrahedral mesh for a 3D-Layered domain
- Many other minor errors…
==================================
Version 3.02.0440 – 10.10.2019
==================================
New add-on Modules:
- Furrow 3D
- Slope Cube 3D
New Features:
- The new ObsNodCh.out output file with EC and SAR at observation nodes of the UnsatChem computational module.
- Export to Paraview: new array “Geo_Numbers” added to “PointData”. This array contains number of corresponding geometric nodes (or “0” if the mesh node does not have a corresponding geometric node”)
- Export and import of the 3D viewing matrix (main menu -> View -> Import/Export View Settings) - allows setting the same view in different HYDRUS projects
- Project Templates and initialization of project from a template (the “New Project” dialog and also Main Menu -> File -> Project Templates)
- New type of selection: Main Menu -> Edit -> Select -> Select by Object Numbers...
- New option to set the factor of translucency for geometric objects, FE-mesh, etc. (Main Menu -> Options -> Transparency Options...)
- Added support for 4K monitors (high-dpi resolution)
- Improved graphical tools “Slicer” and “Clipper”
Fixed Errors:
- Flowing particles were not calculated in 64-bit version (HYPAR and H3D_Calc)
- Error in the Root Water Uptake Parameters dialog (combo-box selection)
- Error in the Heat Transport Parameters dialog for Inverse Solution (combo-box selection)
- Several minor errors when working with bitmaps – see details at https://www.pc-progress.com/forum/viewtopic.php?f=3&t=3418
- Fixed Chart printing
- Fixed about 60 other minor errors in the GUI
=================================================
Version Hydrus3D_3.01.1450 – 28.01.2019
=================================================
Improvements:
- New options in the dialog for importing values from scattered points
Fixed Errors:
- Flowing particles were not calculated in 64-bit version (HYPAR and H3D_Calc)
- Fixed several minor errors in the implementation of Expanded Root Growth (variable plant centers for root growth, etc.)
- An error in the HP2-Components dialog (values in the “component” column were disabled)
- A minor error in the dialog for Chart Options - some check-boxes were not displayed correctly under certain circumstances
- Values in the Time-variable boundary conditions dialog were not updated correctly under certain circumstances
- A minor error in the chart with results at observation nodes (inverse data were not displayed for some boundary conditions BC=7,8,9)
- Several errors in HYPAR - if the Expanded Root Growth or Reservoir Boundary Conditions were used.
- Allowing the Walker equation for both negative and positive exponent
