####################################################


#########   Known Issues   #########################

 * The syntax of database files, *.gps, *.gdr, *.gad, and *.gdt files have changed since the maps are written in YAML syntax
   and new files may contain more than 16 material IDS. For this reason, these files are not compatible with older GeoDict versions.
   * The GAD geometry files can still be saved in the old XML-like syntax.
   * The GDT files can still be saved in the old GDT2 format when the geometry contains only material IDs smaller than 16.
 * It is not possible to directly export multiple result files to a single table in Excel anymore, as it is possible to directly combine result files in GeoDict.
   * From the Excel add-in this feature is still available, but will be removed in the future.
 * The direct specific Excel export, except for the FilterDict module, of GeoDict result files is not available anymore.
    * From the Excel add-in this feature is still available, but will be removed in the future.
 * BatteryDict:
   * The BEST solver do not work when the GeoDict project folder is a network path.
 * The Python functions gd.getBuiltinDefaults(...) and gd.getCurrentSettings(...) cannot convert the settings to an
   older version for all commands at the moment.

####################################################

 * Fixed "Continue on Error" for vary-macros. .
 * Fixed GUI behavior if a macro was varied and afterwards a macro or script without variables is selected (before vary
   was still selected).


Constituent Material Database:
 * If the transfer number of the electro-chemical properties of an electrolyte is changed in the material database dialog
   this change is now always saved correctly to the database file.


BatteryDict:
 * Fixed the initial loading of the Anode.gdt for "Analyze Battery".
 * Fixed small bug for meso-scale simulations in the MesoMeshGenerator which lead, because of rounding errors, to
   a voxel with wrong material ID.

   initial voltage drop for porous separators.
 * Fixed the calculation of the expected cell-SOC range for the constant-potential charging-profile step leading to an
   incorrect time-step size for these constant-potential step.
 * Always consider the complete surface at the interface between active material and porous separator with BESTmeso
   (to be consistent with BESTmicro simulations).


FlowDict:
 * Fixed bug in EJ solver for symmetric (Dirichlet) boundary conditions which was found for a 2D star-case example.

Notes for the GeoDict 2023 Service Pack 3 (66753)
Date: 2023-07-24 (Mon, 24 July 2023)

####################################################


Base:
 * Some minor bug-fixes in the GeoDict GUI.
 * Improved auto-complete in the GeoDict console.
 * GUF-Editor:
   * "Compute Metrics":
     * removed the option "Isotropic" for the direction for the computation of slice-wise minimal, maximal and mean value computation. This option does not work and should not have been in the GUI.
     * removed volume field choice "No field loaded" from the metric dialog. 
 * GAD-Selection:
   * If one edits the GAD selection shown in the according dock-widget on the right side of the GUI the dock-widget stays open now (before it did close automatically).
 * Have consistent voxel length for field and image if one loads a boxel volume-file without resampling to voxels.
 * Don't discard volume fields when undo is used and the geometry size does not change.


Visualization:
 * Fixed automatic scale-bar size in 3D for all possible positions and alignments.
 * Fixed crash when transparency was used with "Interpolation on Visible" when the volume field has a different resolution than the loaded geometry.


Licensing: 
 * The number of free and used licenses was sometimes not displayed correctly in the Manage Floating License dialog and in pop-up error messages. This is now fixed.


Constituent Material Database:
 * Fixed the unit conversion for solid density in the Physics dialog.
 * Fixed the unit conversion for fluid density in the Physics dialog.
 * Fixed copying of a material database file with an alias: now the alias is not copied anymore which prevents the according warning when two materials have the same alias.
 * Concentration dependent values are added to the reference and the metadata of "Electrolyte" in the material database.
   * Also updated concentration dependent values for active materials which are stored in the material database meta-data.


GeoApp:
 * Improved tool-tips for some digital rock Physics apps.


Macros and Scripting (GeoPy):
 * Fixed usage of table variables in GeoPy macros and scripts.
 * In the macro execution dialog show a tool-tip to explain which folder can be removed (or is a default folder which cannot be removed).


GeoDexcel:
 * Make the *.gdr file export to Excel via Python more robust for files which do not follow the GeoDict standards for *.gdr files e.g. created via a GeoApp.


ProcessGeo:
 * If one uses "Reassign Material ID" with the option "Assign Corresponding Material" the properties for "Manual" materials are set correctly now.


ImportGeo-VOL:
 * If the voxel length of a gray-value image is changes during the image processing the new voxel length is handled correctly when "Undo" is used.
   * Also if single gray-value fields have different sizes and voxel-lengths this is shown in the status section now.
 * If one loads a gray-value image into the GeoDict image processing one can save the image again with "File -> Save Volume Field as ..." as *.grw file.
 * If one loads an image stack with the same size as a currently loaded gray-value image the misleading image size message was fixed.
 * When writing Tiff files larger than 4GB GeoDict now writes BigTiff instead of truncating the files. Some other software might nor support reading BigTiff.


ImportGeo-CAD:
 * Fix bug that caused user-given material IDs to be ignored when a mesh was imported via Python macro and the suggest mode was not set to "Manual".
 * Fixed GeoDict crashes when *.obj files without information about objects/groups are imported. This case should work now.


MeshGeo & ExportGeo-CAD:
 * Fixed the surface triangulation of the voxel surfaces with "Avoid Repeating Edges", where the resulting triangulation was not closed before.


BatteryDict:
 * Fixed the reported total overpotential in the *.gdr result-file for the BEST:er-micro solver.
 * Fixed macro-compatibility with older versions, which resulted in an error message for some macros / scripts when one tried to run them with the current GeoDict release. 
 * Currently, LIR calculates the kinetic overpotential of the Lithium reservoir, but does not consider this for the cell potential and as a result the difference between OCV and cell potential is not the same as total overpotential. This was changed for the LIR solver so the behavior is like the one of the BEST(er)-micro solvers.
 * Charging-Profile simulations:
   * Fixed error when running a charging profile simulation, that was caused by the non-charging-profile cell-potential settings.
   * The charging-profile simulations run now also with the new Version of the BEST micro solver.
   * At the moment the charging-profile simulation does not work with the Best meso solver. In this case a proper error message is shown now. This feature will be added for GeoDict2024.
 * Additional references are added to the "Equations & References"-tab in the charge battery and charge half-cell dialog.
 * Make reports from "Analyze Battery" for connected / unconnected active materials in Cathode fit with the data for connected / unconnected active materials in the report of "Charge Half Cell".

 * Renamed the solver "BESTmicro" to "BESTmicro (legacy)".
 * Fixed the initial voltage drop and the overpotential diffusion electrolyte for BESTmeso simulations.
 * Fixed Over-Potential computation in the LIR solver where the diffusive Over-Potential was not computed correctly. Now the total Over-Potential should be the difference between Cell Potential and Equilibrium Potential.

 * For "Effective Stiffness" simulation, a bug in user interface for LIR solver was fixed. The option "Restart from .gdr File" was removed.
 * Using the LIR solver with symmetric boundary conditions the resulting stiffness tensor is now always orthotropic.
 * Fixed large jump in the plot of the transferred charge for battery charging simulation, which could be observed for some simulations.


SatuDict:
 * Fixed crash for the post-processing of resistivity index *.gdr result files.


ProcessGeo:
 * Fixed "Flood Fill Large Pores" when the pores do not have material ID 0.


GridGeo:
 * Fixed usage of the length-unit "Voxel" in the GUI. For the sphere-grid option the "Voxel"-unit was disabled as the voxel-length is computed automatically when parameters are changed.


LayerGeo:
 * Do not allow to choose the "Geometry Mode" "Analytic Geometry" for "Add" and "Subtract" in the GUI, when the GAD data does not match the current voxel geometry.


FoamGeo:
 * Improved generation of periodic Kelvin cells: avoid that structure GAD elements appear 2 times in the generated geometry (this also fixes the *.g32 index image created for such a foam).


WeaveGeo:
 * Fixed weave geometry created with the GeoApp "Orthogonal Weave (Composite)" using the "Single" warp option.


FiberFind:

#########   Complete List of Changes   #############  

Base:
 * The GeoDict installer for Windows does not automatically create the desktop shortcuts for GeoLab and GeoDexcel anymore. To get the shortcuts one has to select this explicitly during the installation process.
 * With the GeoDict installation one gets now example datasets for all our business areas. In Windows these data-sets are automatically installed when "Download example datasets" is chosen during the installation process.
 * The basis data structure for the geometries in GeoDict was changed from 4-bit (16 material IDs) to 8-bit. With this change up to 256 material IDs are possible now.
 * The map syntax for the up to 256 materials was changed to avoid overly long material settings maps. In the new syntax materials of material IDs which are not in the map are implicitly set to be "Undefined".
 * Improved "Undo" and "Redo" of geometry changes: compressed geometries are saved now in memory.
 * The syntax of the *.gps (dialog settings), *.gad (analytic geometry files), and *.gdr (result files) was changed to a YAML:

     * Here, one can automatically upload a single macro run or a parameter study (vary-macro).
     * Clicking the "Run in Cloud", a dialog is opened, in which one can choose the hardware and which files are uploaded.
     * After a cloud simulation is started, a dialog is shown, in which one can see the currently running cloud projects and the finished cloud projects. Here one can also download the results.
   * The "Run in Cloud" button is also available in the GUI of all modules to upload e.g. a single flow computation on the current geometry.
   * One can choose between different machine configurations e.g. with or without strong GPU (for GeoDict-AI).

   * Furthermore a different surface charge can be given per z-layer of the filter media.
 * Analyses the filtration result distinguishing between depth and cake regime and calculate f and sigma for both regimes. These results are added to the result map and the report.

   * By default the saturation field is written but not the pressure field.
   * Renamed "Pressure" field to "Pore Filling Pressure".
   * Renamed "Saturation" field to "Pore Filling Saturation".
 * Added support for thin films to the "Resistivity Index" command:

   * The thin films are then considered between the invading fluid and the solid materials.
   * This feature requires a special license.
 * Fixed capillary pressure values for the "True Contact Angle" method for 2D cases where the value was overestimated by a factor of two.
 * Improved built-in defaults for the "Oil&Gas" edition:
   * The default fluid is now "Water (Brine)".
   * The default solid material is "Quartz".
   * The default settings for "Capillary Pressure" command correspond to a primary drainage experiment.


PoroDict & MatDict:
 * Added the option to compute the "2-Point Correlation" for voxel geometries to MatDict.
 * With "Analyze Objects" in MatDict one can now analyze the currently loaded index images (*.g32).
 * In MatDict "1D Statistics":
   * The estimated solid volume fraction (SVF) of the medium over the thickness of the medium is reported.
   * Beautification and small fixes of the report in the *.gdr result file.


AcoustoDict:
 * Improved layout of and better defaults for the "Match" and the "Stack" dialogs.
 * Added the "Absorption Curve" to the "Delany-Bazley" *.gdr result file. In the command post processing one can change the layer thickness and see how this changes the frequency-dependent absorption.
 * Added the "Absorption Curve" to the "Johnson-Champoux-Allard" *.gdr result file. In the command post processing one can change the layer thickness and see how this changes the frequency-dependent absorption.
 * Allow running flow simulations in AcoustoDict also with the LIR solver.
 * Introduce "Equations & References" tabs in the dialogs and updated the model names.
 * Improved approximation of the viscous characteristic lengths for the "Johnson-Champoux-Allard" model.
 * Changing the default frequencies and the database folder is now a command with the name "AcoustoDict:Config". The changed settings are now also used after a GeoDict re-start.
