MIKE+ 2023 Release Notes

New Features

Modul/Typ Neues Feature
General New unit systems are available for 'Rivers, collection system and overland flows' model type. They control the unit for discharge and volume values in input editors and in results presentation windows.
General The 'Apply' option in 'Rivers, collection system and overland flows' model type and the 'Is active' option in the 'Water Distribution' model type have been added to all relevant editors. When this option is unselected, the corresponding items will be ignored in the simulation without having to create scenarios.
General User-defined columns are now automatically imported from MIKE URBAN setups.
General The 'Import and export' tool allows importing data to and exporting from user-defined columns.
General The 'Import and export' tool offers a new transfer mode to skip the import of records already existing in the target MIKE+ database.
General MIKE+ can now open a .sqlite database even if it doesn't have a corresponding .mupp file. The .mupp file will be created automatically.
General The 'Interpolation and assignment' tool can use feature layers in .xyz format as source for interpolation of data.
General The 'Network simplification' tool can be executed from a command line.
General Any scenario can be converted to a Base scenario, in a new database. This new option is accessible in the context menu of the scenarios tree.
General A new 'Combine tiles' tool has been added to the 'Tools' tab of the ribbon. It merges multiple DEM tiles into a single DEM file for later use in MIKE+.
General In the 'Versions management' tool, the 'Compare' and the 'Update' tools have a new 'Filter on model type' which allows to analyse only the tables relevant for the active features and modules in the project.
General In the 'Versions management' tool, the 'Compare' and the 'Update' tools can compare networks with merged pipes to their original network, to avoid considering merged pipes as new pipes.
Results visualization The 'Results differences' tool can compare link results on networks with merged pipes to results obtained with the original network.
Results visualization The 'Results differences' tool can now also analyse results differences between Water Distribution results (.res files) or between SWMM results (.out files).
Results visualization The 'Compare' button in the 'Results' tree view, used to create a result file with differences between two source files, now supports the following types of files: MIKE 1D results (.res1d), 2D Overland (.dfs2, .dfsu), Water Distribution (.res, .resx), SWMM (.out).
Results visualization 2D Overland results (.dfs2, .dfsu files) can be presented on result maps. It is therefore possible to visualize 2D result maps without opening a model database.
Results visualization The 'Results tables' window has been redesigned. It provides a clearer presentation of tabular data, options to show statistical values for each result location, and new options to select model data based on results selection or vice versa.
Collection System Roughness values can be specified in Manning (n) instead of Manning (M), when defining catchments or pipes and canals.
Collection System SWMM runoff result files (.out) and SWMM outflow interface files (.txt) can be used as input file for 'Inflow from result file' boundary condition in 'Rivers, collection system and overland flows' network simulation.
Collection System A new routing option is available in the 'Catchment connections' editor, to introduce some time delay and attenuation of the runoff hydrograph before it enters the network. This option can be enabled from the 'Network simplification' tool, for catchments which are reconnected after a trimming operation.
Collection System A new button 'Update markers' has been added in the 'Generic shapes' editor for automatically inserting markers at default locations in shapes with type 'X-Z-R-M Open'.
Collection System and Rivers The 'Wave approximation' numerical solution can be changed for selected pipes or rivers, in the 'Pipes and canals' and 'Rivers' editors.
Collection System and Rivers A new 'Variable expression' type of sensor is available in the 'Control rules' module. It allows defining sensors with an advanced user-defined expression, typically as a function of other sensors. The result time series of this sensor can be saved in result files.
Collection System and Rivers A new 'Analyse network' tool is available in the 'Simulation setup' editor for network simulations. It aims a finding and reporting locations prone to instabilities, in order to improve the model stability. Improved stability allows running simulations with longer time steps, therefore resulting in shorter simulations.
Collection System and Rivers When importing a full MIKE FLOOD setup, the River/Urban links from MIKE FLOOD are now converted to connections between the river and the collection system network.
Collection System and Rivers For catchments modelled with the 'RDI' rainfall-runoff method, it is possible to enable an autocalibration of the RDI parameters against a discharge measurement time series. Autocalibration is enabled in the 'RDI' tab in the 'Catchments' editor, and the calibration settings are defined in the 'Parameters RDI' editor.
Collection System and Rivers The symbology for catchment connections can now be customised.
Collection System and Rivers A new type of initial conditions definition, using 'State files', is available in the 'Simulation setup' editor for network simulations. State files are special result files saving detailed information for later use as initial conditions, and therefore need to be saved during a previous simulation. To save state files, a simulation must contain a result file with the new content type 'State files (initial conditions)'.
Rivers A new 'Steady state' type of initial conditions is available in the 'Simulation setup' editor for river simulations.
Rivers For boundary conditions of type 'River Q/h relation', a new 'Compute' button allows estimating the Q/h relation table based on cross section geometry at the boundary location.
Rivers A new type of boundary condition 'Groundwater leakage' is available for river networks.
Rivers A new plot has been added to the 'Culverts', 'Weirs', 'Gates' and 'Bridges' editors. It provides a graphical view of the structures geometries along with their upstream and downstream cross sections, for comparison.
Rivers The main river boundary condition types are now visible on map using new dedicated map layers.
Rivers Muskingum and Muskingum-Cunge routing methods are available for rivers. Routing location and method are specified in the 'Routing' tab of the 'Rivers' editor, after defining the river type as 'Simple routing'.
Rivers Couplings between rivers and MIKE SHE can now be defined in the new 'MIKE SHE couplings' editor. It is enabled by activating the 'Coupling to MIKE SHE' option in the 'Model type' editor. After setting up a river model including such couplings, the .m1dx simulation file must be exported from the File \ Export menu, for use in MIKE SHE.
Rivers A new tool 'Trace rivers from DEM' has been added to the ribbon, in the 'River network' tab. It is used to create new rivers, following highest slopes from a Digital Elevation Model.
Rivers The 'Catchments delineation' tool has been extended to allow creating catchments for river networks, based on a Digital Elevation Model.
Rivers The 'Bed roughness' editor now has a new type of roughness distribution, based on multiple zones on the vertical axis. It also includes a new 'Roughness factors' tab to define constant or time-varying factors to the bed roughness.
Rivers A new tool 'Interpolate resistance' has been added to the ribbon, in the 'River network' tab. It is used to spatially interpolate bed roughness values and apply them to cross sections.
2D overland In the '2D boundary conditions' editor, the 'Source' type of boundary offers a new 'Q/h relation' type of definition, designed to specify an outflow value as a function of the water level.
2D overland 'Saturation' can now be saved as a new result item in 2D result files.
2D overland The numerical scheme for the hydrodynamic calculations using the higher-order scheme has been improved (improvements to the well-balanced scheme; including velocity-based reconstruction of face values), to improve the simulation's stability. This may result in differences of results after updating to this new version.
2D overland The performance of simulations using GPU acceleration has been improved, to reduce simulation times.
2D overland The initialisation phase is now faster for simulations with infrastructures defined with shape files including many thousands of polygons (for example, house footprints to be included in the calculation).
2D overland Stability has been improved for free outflow boundary conditions.
2D overland The log file from 2D overland simulations better reports locations of errors related to 1D-2D couplings, with clear indication of river ID and chainage or node ID.
Water Distribution It is possible to export the network and results data shown on the Profile plot window to a text file. This new option is accessible from the context menu of the Profile plot windows.
Water Distribution In the 'Network simplification' tool, filters are now available in a new 'Select to exclude' tab, to exclude some network element types from the simplification.
Water Distribution In the 'Optimization' special analysis, new target types have been introduced: 'Water quality', 'Pump power', 'Pump energy cost' and 'Pump speed'.
Water Distribution A 'Level control' option has been added to TCV valves to model float valves.
Water Distribution The 'Connection tool' is now available in the 'WD network' tab in the ribbon, to connect demand allocations and measurement stations to the network.
Water Distribution A new special selection 'Pipes connected to selected nodes' has been added.
Water Distribution The 'Zone mapping' tool offers a new option to separate zones based on pipes with user-selected criteria.
SWMM Catchment connection lines are now visible on the map.
MIKE 1D engine Changed behavior of pump sump to use pump stop level for setting initial water level of pump (TT61508).

Fixed issues

Modul/Typ Fehler
General Various unexpected errors, popping up in different situations, have been fixed.
General The pipe direction was unexpectedly taken into consideration when performing a network simplification. As a consequence, pipes could not be merged when they were defined in opposite direction. This pipe direction criterion has been removed.
General Results values shown in X-axes data under a profile plot, were not refreshed when animating results.
General The 'ArcGIS integration' sometimes failed to export geometry data for 1D result layers.
General The 'ArcGIS integration' sometimes failed to export results from 2D result files in .dfsu format.
General An unexpected error could show up when loading some .TIF files as an image layer on the map.
General When joining model data and results in a report table, the table contained some attributes which were not selected in the report settings.
General Levee elevation shown on the Profile plot for pipes defined with a generic shape was wrong, if the last two points defining the shape have the same X-value.
General While running a simulation, the remaining simulation time was always shown in accumulated seconds. It is now shown in hours, minutes and/or seconds.
General Exporting 1D-2D couplings to shape file using the option 'Export selected layers to shape file' from the layer's context menu failed.
General Using the context-menu option 'Show validation items on map', more error locations than expected were shown on the map.
General Working with the 'Use single editor style', clicking the 'Simulation setup' button in the ribbon opened the last opened editor instead of the 'Simulation setup' editor.
General There was an error in the license usage, preventing from importing a MIKE URBAN model into MIKE+ when having only one seat available in the license.
General The same file format for saving symbology configuration can now be used on the main Map and on result maps.
General The 'Preprocessing Temporal Data' tool from the 'MIKE Zero toolbox' always failed during execution.
Collection System Profile plots failed to show results in locations with parallel pipes.
Collection System Catchment connections to 'River junction' nodes triggered an unexpected error when starting the simulation.
Collection System The resistance distribution type was undefined for X-Z cross sections imported from MIKE URBAN setups, instead of being set to 'Uniform'.
Collection System The special selections 'Load points connected to selected nodes/pipes' sometimes selected load points not connected to selected nodes.
Collection System Many unexpected control rules were sometimes imported from MIKE URBAN setups with RTC rules.
Collection System The unit description for values in boundary conditions with type 'Exfiltration from node' was incorrectly showing a discharge unit instead of an infiltration rate unit.
Collection System Points in X-Z cross-sections imported from MIKE URBAN were not sorted by increasing S-coordinate.
Collection System The use of 'Water age' components in the Transport module did not work: the water age remained constant.
Rivers Cross sections were shown on the map even when their chainage was out of the range of the river chainages.
Rivers While selecting result items to be shown in result windows, items from river structures were not correctly categorized, and each structure was presented in a separate category.
Rivers Paths to dambreak time series files were saved as absolute paths in the database, breaking the file paths when moving the database to a new folder location.
Rivers QOF and QIF initial conditions for NAM catchments were imported from MIKE HYDRO River files with a wrong unit conversion.
Rivers While importing full MIKE FLOOD model setups, rivers are sometimes renamed to fulfill MIKE+ requirements, but the river IDs were not renamed accordingly in the imported '1D-2D couplings'.
Rivers Catchment connections to storages on the river network were sometimes ignored in the simulation.
2D overland The option to show a time series file in the time series editor failed in the '2D boundary conditions' editor.
2D overland The size of the MIKE+ database increased when starting a 2D overland simulation even if input data had not been edited.
2D overland An unexpected error occurred during the simulation when applying spatially-varying crest level changes on 2D dikes.
2D overland While inserting 2D dikes using the 'Insert from file' button, dikes' coordinates where not reprojected when the shape file was in a different map projection than the MIKE+ project.
2D overland Attempting to run a 2D Overland simulation using multiple GPUs actually used only the first GPU for all subdomains, hence slowing down the simulation.
2D overland The time for validating the database data was very long, after opening a 2D Overland project involving a mesh with millions of elements and with buildings excluded from the mesh.
2D overland The import of couplings locations has been improved when importing a full MIKE FLOOD setup which was coupled to MIKE 21 classic. XY coordinates of the couplings are now recomputed during the import based on the cell indices defining the coupling location in the MIKE FLOOD file. This new method provides an improved consistency with the MIKE FLOOD model, in case the actual cell indices had been adjusted after the automatic creation of the couplings.
SWMM The conduits' offset values were not correctly computed when the user-defined conduit's elevation was deleted or set strictly equal to node's invert elevation. This was a problem only if changing the network elevations definition to 'Relative depths' afterwards.
SWMM The special selection 'Catchments connected to selected nodes/pipes' did not work in SWMM5 collection system model types.
Water Distribution The 'Cost analysis' special analysis has been reviewed, to provide a better workflow to access results and reports, and also to fix errors leading to different result time series being shown in the editor and in the result file.
Water Distribution When a pump or valve was renamed, its ID was not automatically updated in the 'Real time control' editor.
Water Distribution The 'Refresh connection lines' tool did not refresh connections to demand allocations.
Water Distribution Statistics reported in the 'Statistics and redistribution' table were sometimes erroneous, e.g. in case some network items are included in several zones.
Water Distribution Duration values from the 'Demand predictions' editor, specified in minutes, were wrongly interpreted as hours.
Water Distribution An unexpected error occurred when loading a result layer from a fire flow analysis (.csv file).
Water Distribution Shape files exported from a Network Vulnerability result layer sometimes had missing coordinates for nodes.
Water Distribution Results of an Optimization special analysis could be wrong when the target was defined on a link or with an average value.
MIKE 1D engine Changed variable unit to undefined (TT61943).
MIKE 1D engine Fixed error in LTS simulations when running RR and HD/LTS simultaneously (TT61760).
MIKE 1D engine Fixed errors in application of local initial conditions in collection system modelling (TT61736/61736).
