Hotfixes 2022

This hotfix solves a problem when running ABM templates using the Coupled Model FM in the so called “standalone” mode, i.e., when using pre-computed flow data and a pure ABM template. Without the fix you may experience start-up problems and errors like “Fatal error: Number of sub-domains larger than specified in license file”.

This hotfix corrects a bug that caused MIKE SHE preprocessing to fail when running data assimilation in a coupled MIKE HYDRO River model.

This hotfix resolves some performance problems in ABM Lab simulations with no Eulerian variables (standard concentration state variables). If you experience unusual high runtimes with such a template, use a text editor to modify the setup model file and add a PFS keyword to the section MODEL_DEFINITION in the ECOLAB_MODULE
 
   [ECOLAB_MODULE]
     …
      [MODEL_DEFINITION]
        …
        options = 16
      EndSect  // MODEL_DEFINITION
 
Note that this options keyword represents a binary representation of different flags. The relevant flag is in the 5th bit and the numerical value to set this flag is 2^4=16. Please note that the setup must be started using the MzLaunch utility as the standard MikeZero GUI will remove any extra keyword.

This hotfix solves a problem with catchment connections to storages on the river network, which were sometimes ignored in the simulation.

This hotfix corrects an error that was causing NAM autocalibration to run slowly.

This hotfix resolves a problem with ABM models where there are two initial time steps, i.e. the particle state variables start to be updated after the 2nd time step after a particle release. With the applied hotfix there will be only one initial time step, meaning that state variables will be updated after the 1st time step following the particle release. This can cause slightly different results in ABM models when comparing model conducted with and without the applied hotfix.

This hotfix solves an issue in MIKE ECO Lab causing the H2S template to fail load during simulations, because the build-in forcing “Relative Depth” got wrong properties.

This hotfix solves an error in the license usage, preventing from importing a MIKE URBAN model into MIKE+ when having only one seat available in the license.

This hotfix solves two issues in the 2D overland module, one preventing from applying spatially-varying crest level changes on 2D dikes, the other preventing from using several identical GPUs for the simulation.

This hotfix solves a random problem with the sediment transport table generator only using uniform sediment for the calculations.

This hotfix solves an issue where the Cloud Simulation Launcher cannot upload a model to the cloud if the model setup includes many files.

This hotfix resolves an error in ‘Maps’ results in MIKE HYDRO River, which were sometimes computed based on a wrong list of input DEMs.

This hotfix enables a user-defined limit to the number of irrigation dfs0 output files produced during a simulation. The value can be adjusted using the Extra Parameters feature, by setting the parameter ‘MaxNoIrrigationLogFiles’. The default limit is 100.

The hotfix enables users to work around a bug introduced when distributed vegetation parameter specification was enabled in MIKE SHE. If a user specifies one or more vegetation parameters individually, using a gridded distribution, then the bug results in a generation of a unique irrigation dsf0 file for each grid cell of the MIKE SHE model domain. This causes MIKE SHE to crash if the model grid has more than ~500 elements. 

We plan to provide a more comprehensive fix that will enable users to continue to benefit from the information in the irrigation output files when using a distributed vegetation parameter specification. The more comprehensive fix will be available with release 2023 in November.

This hotfix solves issues with the Cloud Simulation Launcher occurring when previous project folders were no longer available.

This hotfix solves a problem where merging of SW output files after an MPI simulation could fail if the type of output spectrum was NOT "Whole spectrum".

This hotfix corrects a problem in Plot Composer with a warning message that has started to pop up continuously

This hotfix corrects an error which prevented from loading a result layer from a fire flow analysis (.csv file), in Water Distribution projects.

This hotfix removes an unexpected license usage while editing 2D Overland models.

This hotfix corrects a serious error in the transfer of water quality components from MIKE SHE to MIKE HYDRO River when two or more kinds of components are being transferred.

This hotfix fixes current problems in the Mike Basin engine API methods, specifically the correct setup of the simulation time when calling the method “SetSimulationTiming”, which was correctly setting the simulation limit dates, but it was not setting the simulation current time to the starting time of the simulation as it would be expected. The hotfix also extends the error message when a time series file does not have data for a requested date, specifying the complete path to the problematic file.

This hotfix corrects a problem in Water Distribution models, when the nodal demand was not correctly accounted for in the fire flow simulation (related to residual pressure for given flow and flow for given residual pressure methods).

• Incorrect sediment mass within Sigma-Z level grid
• Possible issue when using MPI
• Possible omission of disposal if no disposal output is defined

In addition the hotfix solves a problem where running a combination of Jet source and HD feedback from MT failed when running MPI.

This hotfix resolves an automatic unit conversion issue in the control module when using time series in a unit different from SI base unit. This is relevant in MIKE HYDRO in rule actions, when “Action” - “Value type” is “Time series”, and in MIKE 11 for all time series used for control structures. The time series values are now automatically converted to the unit of the engine (SI base unit) before being applied.

This hotfix solves an issue with color legends not being shown when exporting plot.

This hotfix corrects a memory leak that affected performance when running the MIKE ID Control Module from a script.

This hotfix solves a problem in the DHI License Updater.

• possible memory issue when using the Shoreline Module in a domain that is resolved by many elements
• error in the Spectral Wave module related to reflection from structures in combination with the use of “Directional sector” for the directional discretization
• error in the Spectral Wave module in case of wave blocking using current in combination with quasi-stationary formulation for the fully spectral formulation
• error in the Mud Transport module related to use of hindered settling
