HOTFIXES FOR MIKE 2019 Update 1

MIKE URBAN hotfix 02-12-2019

This hotfix corrects two issues in MIKE URBAN when running the MIKE 1D engine. When a lot of link regulation or pump wet well set points are specified in the setup, an error mentioning “MaxStringContentLength for XmlDictionaryReaderQuotas“ has been resolved. When MIKE URBAN classic RTC were failing when controlling a pump start/stop level with absolute or relative time or a dfs0 file has been resolved.


MIKE URBAN hotfix 07-11-2019

This fixes the resetting of structure status before each job for LTS simulations using MIKE 1D

MIKE HYDRO/MIKE 11 hotfix 25-10-2019

This hotfix handles an issue where memory is not released at end of an RR simulation. In online scenarios with multiple runs this can be an issue.

MIKE HYDRO hotfix 16-10-2019

This hotfix corrects an error in the date range used in output dfs2 files interpolated from MIKE 1D simulation results.

MIKE HYDRO hotfix 11-10-2019

This hotfix handles an issue in the MIKE HYDRO ST module, where the ST inflow for point sources and distributed sources are ignored.

MIKE HYDRO hotfix 10-09-2019

This hotfix enables the writing of irrigation node identifiers to irrigation output files in MIKE HYDRO Basin simulations. The hotfix also enables running MIKE HYDRO Basin iteratively from a script without re-initializing the model before each simulation is executed.

MIKE HYDRO hotfix 29-08-2019

This MIKE HYDRO Basin hotfix corrects errors in the irrigation water balance, ensuring that deep percolation from irrigation is routed to groundwater and that irrigated areas are subtracted from groundwater recharge estimated by the NAM model.
The hotfix also corrects two errors in the operation of series reservoirs, making it possible to 1) convey water through the natural channel when reservoirs are located on the same branch and 2) link irrigation users to the downstream of two reservoirs in series.

MIKE Zero hotfix 19-08-2019

This hotfix resolves a problem in the HD FM module that could prevent the simulation from running in GPU mode when using structures in a Sigma-Z level domain.

MIKE Zero hotfix 15-08-2019

This hotfix resolves a problem in the HD FM module that in rare cases could result in an ‘Illegal storage access’ error message when using the ‘Free outflow’ boundary condition.

MIKE URBAN hotfix 06-08-2019

This hotfix for Runoff Model B fixes the simulation of runoff event endings appearing close to the simulation end time.

MIKE 11 Hotfix 01-08-2019
This hotfix corrects an error that occurs when AD is enabled, and there is a HD+AD boundary where the HD contribution is disabled, and AD concentration is provided in a time series file. The unit from the time series file is now used as basis for unit conversion when applying the concentration value to the engine.


MIKE SHE hotfix 01-08-2019

This hotfix corrects an error in the preprocessing of a coupled  MIKE SHE - MIKE HYDRO River model. The problem arises for MIKE SHE models linked to a complex river network with several bifurcations and confluences, for which the branches are not connected correctly in MIKE SHE, and this leads to incorrect numerical results in the coupling simulation, especially in the discharges between the MIKE SHE and the river model.


MIKE URBAN hotfix 23-07-2019

This hotfix enables MIKE URBAN users to define initial conditions for a MIKE 1-D simulation using an adp file, in the same way that users can define initial conditions for a MOUSE simulation.


MIKE Zero hotfix 22-07-2019

This hotfix corrects errors in the updating of reservoir dimensions in MIKE HYDRO Basin when the sediment transport module is enabled.


MIKE Zero hotfix 16-07-2019 (MIKE View)

This hotfix enable users to load large prf files in MIKE View for results viewing and analysis. Two hotfixes are available: one that fixes the version of MIKE View installed with MIKE URBAN and the other installed with MIKE Zero. Users with both MIKE URBAN and MIKE Zero installed can run either hotfix.



Hotfixes for MIKE 2019 (no service pack required)

MIKE URBAN+ hotfix 03-09-2019

This hotfix solves two issues preventing from running simulations. The first issue occurs with the Water Distribution module, where the simulation cannot start when the model contains pumps with a 3-point curve type. The second one is a wrong license verification, preventing from executing a Collection System simulation with pipe regulation if the license doesn’t include the CS-Control module.


MIKE URBAN+ hotfix 24-07-2019

This hotfix solves an issue where some of the dialog contents could not be fully displayed.

MIKE URBAN+ hotfix 11-07-2019

This fix allows the import of a MIKE URBAN model into MIKE URBAN+ after installation of the MIKE URBAN 2019 Update 1

MIKE URBAN+ hotfix 28-05-2019

This hotfix corrects the issue related to projection misalignment of models in US-UNITS in MIKE URBAN+, after import from MIKE URBAN.

MIKE HYDRO hotfix 20-05-2019

This MIKE HYDRO Basin hotfix corrects the remote flood prioritization over the water user extraction in the downstream stream. It also prioritize the maximum release rule, over the remote flood control rule, so the Maximum release will not be violated, in order to satisfy the remote flood control. At the same time, the spill release from the spillways is enforced, as it is supposed to model an uncontrolled outlet.  

MIKE URBAN hotfix 30-04-2019

This hotfix solves an unhandled exception when attempting to report differences between child scenarios and alternatives in the tool Scenario Manager combined with SWMM mode 

MIKE HYDRO hotfix 04-04-2019

This MIKE HYDRO Basin Hotfix corrects the need to limit the release of a Rulecurve reservoir to its maximum release while its spill should be unlimited. Besides, the remote flood control rule should not violate the maximum release of the reservoir in order to be satisfied, so it will stay unsatisfied, if not possible without violating the maximum release rule. Finally, the hotfix gives higher priority to the remote flood control release than to the water users. Previously the maximum release of the reservoir was violated, so the priority between water users and remote flood control requirement was not an issue. 

MIKE URBAN hotfix 04-04-2019

This hotfix corrects the functionality of the catchment connection tool with a SWMM network in MIKE URBAN.

MIKE URBAN hotfix 20-03-2019

This hotfix corrects a problem in MIKE URBAN RTC where a condition containing a “function-active” produces an error in the first time step

DHI License Manager hotfix 04-03-2019

This hot-fix resolves issues in license manager when user does not select to reset log level changes after 12 hours.

MIKE URBAN hotfix 27-02-2019

This hotfix fixes the creation of 2D result layers from Overland Results in MIKE URBAN.

MIKE URBAN hotfix 27-02-2019 – b

We have encountered instances where Windows Defender will flag certain files as being infected with a trojan virus. This is a false/positive detection and this hotfix replaces the files in question, which solves the problem.



MIKE URBAN hotfix 26-02-2019

This hotfix fixes the application of minimum and maximum time step defined in the LTS job list file with the MIKE 1D engine.



MIKE URBAN hotfix 11-02-2019

This hotfix fixes the application of Job Start and Stop conditions for generation of LTS job list with the MIKE 1D engine.

MIKE 21 hotfix 28-01-2019

This hotfix corrects a problem where MIKE Zero cannot open a MIKE 21 classic version .m21 setup file, after a timeseries .dfs0 file has been loaded in the “Source and Sink” Hydrodynamic Parameters.


MIKE URBAN hotfix 23-01-2019

This hotfix resolves issues in the MOUSE Engine related to UWC (User Written Control) and in online application of the MOUSE Engine from scripting through the COM-interface.

For these applications the feature for controlling the set-point value of PID-controlled weirs and gates did not work correct in Release 2019 and former versions. Now fixed for Release 2019 by this hotfix.

Note: The feature works correct when using the MOUSE Engine directly from the MIKE URBAN Model Manager both in Release 2019 and in former versions.
