Hydrus 3.x User Interface and Point Export

Post by garyhecox » Tue Feb 12, 2019 3:14 pm

Good morning,
I have been using Hydrus 3.x for a couple months now and here are some suggestions with the graphic interface and model export:
1. It would be good if the user could turn off the line numbering but leave the lines on when working with geometric objects in Domain Properties, Initial Conditions, and Boundary Conditions. Numbering the lines can get pretty cluttered (see screen cap). The work-around is to turn the Lines off in the View tab on the bottom of the Navigator bar (next to the Data tab).
2. When a bitmap model background is displayed, results to not show up at the cursor position (see screen cap). It would be good if the user could display the results without turning the bitmap off as it was in Hydrus 2.x. The work-around to display results at the cursor is to turn the bitmap off in the View tab.
3. The XYZ coordinates won't display for the finite element mesh is a bitmap is turned on. Work-around is to turn off the bitmap.
4. The XYZ coordinates of observation nodes won't display when pointing to the nodes on the mesh even with a bitmap turned off. This is important because we use the Z coordinate to set up the elevations of the nodes for flow model calibrations.
5. It appears that being able to use a log scale for the Y-axis is no longer an option in the Observation points graphs. This is a minor thing but log scales are useful when modeling contaminant transport. Work-around is to export the data to a text file and import into Excel.
6. The Export All button in the graph menu creates a file with no results in it. Button probably should be removed if this can't be fixed.
7. Is there any way to export the geometric objects point numbers along with the geometry? As an option, is it possible to sequentially renumber the points? The reason is that we use the point geometry coordinates in flow model calibrations to match observed data and simulated results. (We need the model elevation of an observation node to calculate the offset to match observed groundwater elevations. See attached PDF.) Since observation points on geometric objects are assigned by point number, it would help to have the point numbers in the export file to lookup the geometry. The work-around is to manually get the coordinates from the Point Data menu. This gets a bit cumbersome with a lot of observation points or changes to observation points.
8. It would be nice if there was a calibration module in Hydrus but this is probably a bit far down my wish list. At this point, we export the temporal model results to a text file, import the text file results into an Excel file where the data are assigned to the appropriate observation nodes using a couple formulas and lookups. We then export the observed and simulated values to a statistical program to generate the calibration graphs. In this manner we have been able to use temporal calibration procedures to successfully calibrate our Hydrus models (flow and transport) to real-world conditions.
Thanks,
Gary

Gary,
thank you for your comments and suggestions. I have passed this information to our programmers.
Mirek

P.S.: As for the mapping topological objects to mesh entities (e.g. geometric points to mesh nodes), we are planning to add all these maps to VTK files (*.vtu format - see vtkXmlUnstructuredGrid, https://vtk.org/doc/nightly/html/classv ... riter.html). This will allow various filtering of graphical outputs in Paraview (see also HYDRUS main menu - File -> Export -> Export Data to Paraview), as well as reading these maps by external programs using the vtkXmlUnstructuredGridReader. This new feature will be available in the next version of HYDRUS 3.02, that will be released in April 2019.
