Hotfixes for MIKE 2019 (no service pack required)

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 URBAN hotfix 07-02-2019

This hotfix reenables the option to delineate catchments based on a digital elevation model (DEM) as input.

MIKE 3 hotfix 04-02-2019

An error has been corrected in MIKE 3 Wave Model FM in connection with porosity. The error occur when “Porosity zones (3D map)” is used and the porosity zone is located on land.

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.

MIKE HYDRO hotfix 23-01-2019
This fix filters inaccessible variables from the MIKE HYDRO Basin WQ Parameter add dialogue.
MIKE HYDRO hotfix 21-01-2019
This MIKE HYDRO Basin hotfix corrects the failure to apply supplied demand rules for water users connected to Lake reservoirs. The fix allows all users directly connected to a lake reservoir, to receive water from the lake, if any is available. The hotfix applies for both, local and global priority algorithms.

MIKE HYDRO hotfix 15-01-2019
This hotfix corrects a problem where the import and export tools in the Cross section editor was missing when cross sections were edited as a part of a MIKE HYDRO River file.

MIKE FLOOD & MIKE SHE hotfix 10-01-2019
This MIKE FLOOD hotfix corrects the wrong verification of urban-river links, where an urban-river link could rice the error message: “ERROR: could the node ‘node name’ belong to more than one reach?”, even though the model does not have any such error.
In Models coupling river Models with MIKE SHE, it also corrects an error in the cross-section data passed to MIKE SHE. The corrected error involved the bed and bank level information, which was incomplete.
MIKE URBAN hotfix 03-01-2019
This hotfix address a problem in the MIKE 1D engine with an extreme fast response of the Model C2 (French Urban) RR runoff for catchments with impervious area between 6 and 250 ha and where the lag time is not specified explicitly

MIKE URBAN hotfix 21-12-2018
This hotfix solves a potential problem with importing and/or exporting groundwater flow from .inp files generated in the EPA SWMM 5.1.12
MIKE 3 hotfix 23-11-2018
An error has been corrected in the implementation of the vertical convective terms in MIKE 3 Wave Model FM. In addition the settings for the precondition method used for solving the Poisson equation in MIKE 3 Wave Model FM has been changed. Now a 2-level incomplete LU factorization is used, which improve the convergence also for cases with large variation in the layer thickness for the vertical discretization.
