- Export chart data to CSV file
- Support for rotated numerical grids in numerical workflow (when create new grids, for MODFLOW-2000 and 2005)
- Improved usability for workflows (better defaults when importing models or generating numerical models from conceptual models)
- Fix the default zoom level for the 2D (layer view) in the Flex Viewer, when at the View/Grid step and View/BC step (in MODFLOW-2000,2005 workflows)
- Create the Grid Specification File (GSF) during MODFLOW-USG translation (reserved for future development, including MODPATH-3DU and PEST)
- Export pathlines to polyline shapefiles
- Add option to assign new Specified Flux Boundary (assign / polyline, assign/polygon), in the numerical workflow (Available for MODFLOW-2000, 2005)
- When show unstructured grids in 3D viewer, added option to view the cell geometry as smoothed continuous surfaces (and not discrete flat top/bottoms)
- At the Define Boundary Condition step in numerical workflow, added option to create numerical boundary condition from existing data objects (polygon, polyline), (excludes Well objects.) (Available for MODFLOW-2000 and 2005)
- Improvement in the way time schedules are handled for boundary conditions, to catch boundary conditions that have start/end times that are inconsistent with other boundary conditions.
Fixes
- Could not create thin layers (less than 0.01 m or ft) at the Create Grid step in Numerical workflow (MODFLOW-2000 and 2005)
- When export raw point, polyline, or polygon data to shapefiles, VMOD Flex did not create shapefiles correctly. In some cases, the shapefiles could not be loaded in Third-party software
- In the Import Data window, wells shows up twice in the list of data object types, after you close and reopen a project
- The attributes below the Layer view (on status bar) did not refresh when changing the mouse locations for rotated grids.
- Inactive cells were not showing up correctly for models with rotated grids
- At the end of the PEST workflow, after save results as new run, in the new model run the head observations were not included on the model tree.
- Could not create numerical grid with certain layer number configurations
- PEST - after doing update model inputs, the PEST workflow was also being cloned
- When edit a conceptual boundary condition, the attribute values for species concentrations did not show up
- In settings for imported 3D Grid object (.HDS) the transient output times were not showing correctly
- During import VMOD Classic model with a few thousand wells, there was a very long delay when calculating time schedules
- For a USG Grid, 3D Viewer, displaying Cells, the Legend option was not working
- After import 3d grid object (HDS), the time values were not using the correct units from the project settings
- Transparency did not work for 3D Gridded objects (eg. MODFLOW conductivity) for cells view
- Error saving project, with USG numerical models (only occurred in certain computer/regional setting configurations)
- Stand-alone 3D viewer was showing results from previous MODFLOW run (and was not refreshing after a re-run of the model)
- After importing a Surface data object, when View Spreadsheet, values were showing duplicate XYZ values.
- Storage property zone values were flipped/mirrored after importing a model from VMOD Classic
- Error during import of project with rotated particles, and particles did not show in the correct location
- 3D view, Z axis labels were mirrored/flipped, when viewing simple surfaces.
- Improved the loading time in Flex viewer when displaying Recharge and EVT Boundary Condition cell zones.
- Define Properties step in numerical workflow was reverting back to displaying Conductivity every time you return to this step
- The status bar was cutting off the last few digits for Kx, when the value is E-04 range, and was incorrectly rounding up
- When importing a surface, if you chose a text file that contains XYZ points, and not gridded ESRI ASCII .GRD, you got an error.
- Improved engine run times by disabling detailed logging.
- In PEST workflow, were encountering error when trying to generate .PST file at the Sensitivity Analysis step (with certain parameter configurations)
- When edit attributes for Specified Flux numerical boundary condition, the wrong units were being displayed.
- MT3D runs failed due to problem with MXSS value in the SSM package
- Improved error message at Translate step, when using the Initial Heads option “ Use Heads from previous MODFLOW Run” and the .HDS file could not be found
- Error "object reference" occurs if you add a structural zone to the grid without first creating a new property zone (in Conceptual Model workflow)
- Fixed the zoom level for 2D view by Row or Column, when you adjust the vertical exaggeration
- In 2D viewer, when editing points, it was taking a long time to add new points when other viewers were opened.
- Unable to import well data (Excel data file-specific), and unable to convert pumping rates from L/day to project units.
- 3D viewer, Settings/Isosurface, the correct values were not appearing when returning back to Edit an Isosurface
- Added option to Edit/Single and Edit/Group for Specified Flux boundary condition in the numerical modeling workflow (MODFLOW-2000 and 2005)
- MODFLOW USG, 3D viewer, showing slice, when reload style settings, make change to slice, it restores the Cells view.
- Increased precision for the label for time values in the Head style settings
- Improved the conversion time for Recharge and Evapotransperation boundary conditions when going from Conceptual Model to Numerical Model (MODFLOW-2000, 2005 and LGR)
- Error when trying to create a surface with a blank point data object
- Get error when creating a Surface if using points object created from an operation. (eg. well tops or HGA XS)
- Fixed the behavior of the Assign and Edit buttons at the Define Boundary Conditions step (Numerical Workflow) in the event when you do not complete one of the selected actions; added an option to “Cancel Editing” when right-clicking on the view, will take you back to the original state.
- Define Particles, when add new particles this was always overwriting the previously defined set of particles
- Import Surface data object, if you chose a .txt file that is not ESRI ASCII grid format (such as XYZ points), you would encounter a non-user friendly error
- When creating Voronoi USG grid consecutive times with the same grid generator settings, the resulting grid cell count was not exactly the same
- Error message and program freezes when importing certain polyline objects
