3D Grid

• 12180 Extra "Projection:" field in the 3D Grid Properties table dialog.

MODFLOW

• 12143 MF2K Incomplete Files when Saving Native Text. When the native text files are saved to run it through a USGS executable, and only the *.dis and *.obs files are in the *_MODFLOW_text folder. Using MODFLOW | Advanced | Export Native Files as a workaround caused the same error again using the USGS code.
• 12102 Multiplier in Stream package isn't preserved.
• 12100 MODFLOW-USG files incomplete. The model runs as it is with the USGS executable, but when imported to GMS and trying to run with the h5 executable there are array size issues. Running the text files saved by GMS is not an option because only the BA6, DISU, and GNC files save. However, running the USGS executable with the h5 files appears to work.

Time Series

• 12079 CCF removed due to time step issues. After successfully running MODFLOW, when selecting the CCF file, an error appears that the time steps for the CCF file do not match the existing time steps and the file is removed.

UGrid

• 12118 UGrid XYZS S portion of toolbar not active.
• 12113 Lock and unlock03: Error saving UGrid after constraints have been set to none.

Vectors

• 12150 Incorrect Dataset Export for Vector Datasets. Vector datasets, when exported in ASCII format from GMS 10.4, do not accurately write the dataset information. The exported values are written in a single column, rather than 3, so only the first part of the XYZ values are written, and they're written as a single component. When this dataset is reloaded, it appears as a scalar dataset.

GMS 10.4.7 - November 11, 2019

Export

• 12009 Exporting 3D Grid to shapefile does not include selected dataset. When exporting a 3D Grid as a shapefile, there is an option to export a selected dataset. However, no matter which dataset is selected, the resulting shapefile does not include it. The datasets appear to export fine through the 'all datasets' or 'active dataset' options.

MODFLOW

• 12032 MODFLOW-USG Transport: Loading native solution does not load CON file(s). After running a project from native files, GMS will read the MODFLOW solution but does not load the CON file. There is a CON file with the native solution.
• 12096 MODFLOW simulations are removed after opening with Save boundary fluxes option turned on.
• 12081 Reducing Stress Periods manually disrupts ET array. Adjusting the number of stress periods by manually deleting rows, rather than adjusting the number in the scroll box, and after saving and reopening the project got an error that the ET array had improper dimensions. If the number of stress periods is corrected by editing the number in the scroll box, the error does not appear.
• 12031 MODFLOW-USG Transport: Adding RCH package leads to unsuccessful model run.
• 11949 PEST inconsistencies. In some cases, upon running MODFLOW, PEST does not create iterations or plots. However, if the project is saved and MDOFLOW run again, PEST appears to work.
• 11996 MODFLOW 2000 model gets stuck on RCH package. When importing the *.mfn as a MF2K model, the model appears to translate successfully but then gives an error concerning the RCH file. If the RCH package is commented out of the MFN, the rest of the model loads without issue.
• 11970 CLN inputs incorrectly read by h5 version of MODFLOW-USG. The FELEV input from the CLN is not correctly echoed in the OUT file from the h5 executable. The native files/executable echo correctly.

MODPATH

• 12067 MP3DU cannot find CCF. For reasons unknown, modpath is giving an error in the log that there was a problem opening the MODFLOW CCF file. It appears that the file is not correctly called, because the error lists () as the CCF file.

Opening File

• 12008 Importing MFN for USG model nonresponsive. When trying to load in a MODFLOW model from the MFN file for a USG model, GMS does not give any indication that a file import was attempted, let alone load the project.
• 11977 When there is a large model (over 1 million cells), Map to MODFLOW causes GMS to become unresponsive.

Popup Menu

• 11801 Right-clicking is not consistent for Qt menus. Menu does not always appear.

Quadtree

• 11969 Refining quadtree fails to copy datasets to new UGrid.

UGrid

• 12055 UGrid created outside GMS should have flag when editing elevations from Cell Properties dialog. When attempting to edit elevation arrays through the Global Options, a warning appears that the elevations cannot be edited because the UGrid was not created by GMS. However, when selecting cells, right-clicking, and selecting 'Properties', the same flag should appear but does not.
• 11984 UGrid MODFLOW head solution not accessible from array editor. When selecting a dataset to assign to the UGrid through an array editor (e.g. Starting Heads), any dataset in a subfolder is not available as an option.

Closing

• 11944 GMS process lingers when closing GMS.

Contours

• 11989 Block Fill contours broken for 3D Grid cross sections. When a cross section is created, the contours appear not to work. However, upon closer inspection this only affects the contours when set to Block Fill. Also, if the 3D Grid Data toggle is turned off, the cross section contours are still visible - the toggle does not also completely toggle off the grid cross sections, even though they are nested under that folder.

Export

• 11975 Shapefile Export Error. When attempting to export a scatter set with multiple datasets as a shapefile, an error stating "Error adding one of the function fields" is generated and the shapefile is not created.

Interpolation

• 11950 Select "Use reference time" option crashes GMS. After interpolating a transient scatter set from a scatter to a tin, checking the "Use reference time" option in the dataset calculator causes a crash.

Mesh

MODFLOW

• 11962 Model converges in GMS 10.3.5 but diverges in 10.3.8 or 10.4.5.
• 11688 MODFLOW-USG Transport tutorial files do not converge. Caused by MODFLOW-USG Transport code update. Updated tutorial.
• 11836 PEST is not getting consistent results. Is an issue with parallel PEST and communication with the slaves. Issue is related to PEST, not GMS. Aquaveo cannot fix this.
• 11791 DDREFERENCE not supported in OC Package. Has been implemented.

Project Explorer

• 11995 Slashes / \ or other symbols or special are removed from item names in the Project Explorer.
• 11991 Zone Budget ID is in the wrong place in the Project Explorer.

Menu

• 11883 Add invert selection option to right-click menu in main display.

MODFLOW

• 11907 Copy + Pasting leads to Incomplete parameter rows leads to GMS crash. Since the MODFLOW Parameters dialog didn't initialize all parameters, a list was copied from Excel to paste into the Parameters dialog. However, if the user attempts to exit the Parameters dialog before all fields are filled, GMS crashes. However, at least the 'Tied' field does not allow itself to be filled.
• 11798 LAK package Theta. For steady-state models, if the user enters a non-zero value as theta in the LAK package, the value is not retained when the project is saved, closed, and reopened. The value is also not written to the native *.LAK file.
• 11885 CLN Observations not handled correctly for PEST. When attempting to run PEST in a project where it should run, it gives an error that it can't open *.pval_1. This is because *.pval_1 was not written. The *.ins file is empty.
• 11829 MODFLOW Check Simulation crashes GMS. The problem is due to mixing STR and SFR2 arcs in the same coverage. This shouldn't be done.
• 11627 MODFLOW-USG Translator won't open files. The UGrid for these files is apparently very large, because the DIS and GSF files are both over 1 GB. When attempting to read into GMS, the 64-bit version gets further than the 32-bit version, but still gives an error when converting the GSF to VTU. In GMS 10.3 the files translate successfully but then also give the GSF to VTU error.
• 11834 mod-PATH3DU Error requires LIST to be first. Running an MP3DU set gives error "FIRST ENTRY IN NAME FILE MUST BE LIST" which suggests an issue may be with the exported file.

MODPATH

• 11843 Tutorial Review: MODPATH Polyfill not displaying. Turning on the Poly fill options is not showing a fill behind the pathlines.
• 11842 Tutorial Review: Particle set ordering not functioning. When there are multiple particle sets, the order in the project explorer is being ignored in the Graphics Window. Instead, GMS seems to be arbitrarily displaying the particle sets in the Graphics Window.
• 11841 Tutorial Review: Changing particle duration creates new coverage. Changing the particle set duration is creating a new map coverage with an arc showing the capture field. Also, often this arc/coverage can't be hidden unless the Show Inactive Coverage display option is turned off.

MT3DS

• 11820 Crash when turning on load solution checkbox after MT3D encounters an error.

Online Maps

• 11823 Online images not showing when zoomed in too far. Online images was not grabbing lower resolution images when a higher resolution image was not available.

GMS 10.4.4 - May 02, 2019

3D Grid

• 011774 Splitting layer crashes GMS. Discovered when creating a new K boundary on a 3D grid caused GMS to crash.

Feature Object

• 11735 Drain observation not labelled, does not plot. When an observed flux is used for drains, the words "observed flow" are missing from the status bar. Also, the S/S Flow vs. Time plot only shows the calibration target values are shown even when the box for observed values is selected. This is a MODFLOW-USG simulation on a UGrid.

MODFLOW

• 11780 GMS crashes when opening file saved with many CLN TransientIBOUND inputs. When copy + pasting transient IBOUND data into the CLN package, it appears to import OK. However, once the project is saved and then tried to reopen, GMS crashes.

Online Maps

• 11794 Add online maps doesn't load the desired image.

Save

• 11729 Display Theme options incorrectly executing. The end user originally reported that the display theme options didn't always save when the project was saved, closed, and reopened, but in addition to that we also found that the display options don't behave as expected when turned on or off in the first place.

GMS 10.4.3 - April 16, 2019

Interpolation

• 11454 Tutorial Review: Interpolate Raster to Feature Objects issue. The elevation values from rasters were only being interpolated to the nodes of feature objects and not to the vertices.

Legend

• 11534 Missing MODAEM Legend. Turning on the legend would not cause the MODAEM legend to appear.
• 11460 Legends not appearing consistently. When using UGrids, not all of the UGrids legends would appear and those that did would overlap each other.
• 11409 Legend Text Color Options. In earlier versions (verified in 10.0 and 10.1) the legend text would be white if the background was set to a darker color. In more recent versions, the text stays blank and is difficult to read.
• 11429 DEM legend moved to be displayed incorrectly in the center of the DEM.

Main Menu

• 11459 Contour Options is always enabled when using the Display | Contours Options command.

Materials

• 11501 Deleting last HUF material causes crash. When first opening the HUF package, there are no materials listed. When adding a material and then attempting to delete it, GMS crashes.

MODFLOW

• 11544 Crash opening USG native MFN. When attempting to load in the native MFN file written out by GMS, the MODFLOW translator runs successfully, but when the project tries to load, GMS crashes.
• 11507 MODFLOW-USG not using all observation points. It was not creating a gauge or calculating the head for all points.
• 11556 GMS vs native results with pilot points. When changing interpolation settings for pilot points (e.g. using the nearest 16 points down to the nearest 4 points), the head solution in the GMS run does not match the head solution from the native files written out from the same run.
• 11551 MODFLOW-USG different results running native files; the heads are noticeably different between the GMS files and the native files.
• 11500 Capture Zone solutions display simultaneously. When you select a capture zone solution, then scroll with the up/down arrow keys to other solutions, the first solution is still displayed and two solutions are visible at once.
• 11391 MODFLOW-USG results incorrect when observation on dry area included. When an obeservation point is included over a dry area of the model, the head values end up being all the same. When the dry observation point is removed, the values return to what is expected.
• 11481 CCF does not match grid. After running a transient MODFLOW, the CCF file does not match the grid that was just used to run MODFLOW.
• 11463 MODFLOW HOB bug. Observations that are at the end of sp1 and the beginning of sp2 are assigned to sp2 at time 0 and it makes the most sense for them to be assigned to sp1 at the end time.
• 11482 MODFLOW Steady State solution keeps transient time steps. When a MODFLOW model is changed from transient to steady state and rerun, the solution keeps the transient steps.

Observations

• 11490 CLN Well Observations map to MODFLOW incorrectly. When mapping CLN observation wells to MODFLOW, one of the non-pumping wells maps to 'Well To Node' instead of to 'Cln Well To Node' like the other non-pumping wells.

Particles

• 11390 Generate particles at wells in MODPATH was not detecting wells that are selected.

Plots

• 11319 S/S Flow vs. Time plot always enabled even when it should not be a valid plot option.

UGrid

• 11510 UGrid swap tool not working as expected with the tool swapping edges in an unpredictable manner.
• 11509 UGrid split/merge tool not finding correct edge when merging or splitting UGrid cells. This caused the wrong set of cells to be merged or split. In some cases GMS would not allow merging or split even though the criteria had been met.
• 11470 Unexpected behavior when converting Map to UGrid with a selected Map node. The Ugrid was displayed incorrectly after generating the UGrid until refreshed.
• 11431 GMS hanging when creating UGrid points in the UGrid module.
• 11461 Unable to unlock UGrid for editing.

Vectors

• 11489 Velocity vectors were not being extracted from CCF when using the Extract Velocity Vectors command in the Project Explorer.
