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.

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.

MIKE FLOOD hotfix 27-06-2019

This hotfix corrects an issue in MIKE FLOOD for a lateral link when AD is enabled, and the lateral link starts or ends in the middle of branch at a point at or very close to a connection to another branch.

MIKE URBAN hotfix 19-06-2019

This hotfix corrects the issue related to the visualization of the derived results “Link's absolute discharge versus Q Manning” and “Q Manning” in MIKE URBAN with MIKE 1D engine.

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

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.
