Hotfixes for MIKE 2016 (Service Pack 3 required)

MIKE 21 hotfix 07-05-2018

This hotfix resolves a read-in problem of pier data in the ‘classic’ MIKE 21 Flow Model.

MIKE HYDRO hotfix 18-04-2018

This MIKE HYDRO Basin hotfix fixes the auto-calibration process for a NAM simulation, when the use of the CK2 NAM parameter is unchecked, in which case its value is used but not calibrated. The correct behaviour is that the value of CK2 is locked to the value of CK1, which is optimized by the auto-calibration process. The hotfix corrects this issue.

MIKE HYDRO hotfix 01-03-2018

This hotfix corrects the failure in running the MikeBasin Engine in an optimization loop producing a crash in the external controlling loop. The problem does not occur in individual simulation of a MIKE HYDRO Basin setup.

MIKE HYDRO hotfix 21-12-2017

This MIKE HYDRO Basin hotfix corrects the enforcing of the maximum allowed downstream release of a Reservoir in the context of the Global ranking allocation algorithm. To account for the maximum release it considers the releases downstream and down releases redirected to a connected hydropower.

MIKE HYDRO hotfix 02-11-2017

This MIKE HYDRO Basin hotfix routes the global ranking reservoir releases through the Hydro-Power plants, when the corresponding checkbox in the individual hydropower properties is checked. At the same time reports the flood control releases as spill release.

DHI Internet License Server hotfix 14-07-2017

The DHI Internet License Service has been updated. If you are using an Internet license you need to install this hotfix.

Installation of previous service packs is not required for this hotfix to work.

This exporting capacity enhances communication for external data handling workflows.

MIKE HYDRO hotfix 15-05-2017

The following MIKE HYDRO Basin Hotfix corrects an existing limitation to 510 time series for all catchments, when the weighting time series has been included in a rainfall runoff simulation of a Mike Hydro Basin model. With the fix, no limitations in number of time series exists in practice.

MIKE HYDRO hotfix 05-05-2017

This MIKE HYDRO Basin hotfix disable an outdated warning from times when routing branches were not allowed in branches located downstream to a confluence node or downstream to a reservoir node. This hotfix does not change the computational engine’s behaviour, but only disables the incorrect and unnecessary warning message.

MIKE URBAN hotfix 07-04-2017

This hotfix addresses a problem with MU-EPANET calibration plots, enabling the tool to create plots for node pressure and flow TS.

MIKE URBAN hotfix 05-04-2017

MIKE URBAN hotfix 15-03-2017

This fixes several issues in the MIKE 1D and MOUSE engine: In the HTML summary, the Catchment continuity balance has been fixed for RDI/NAM and combined catchments (RDI+A etc.). The runoff model C2 (French model) using Horton Infiltration has been fixed, and also use of an unspecified lagtime has been fixed. The runoff model UHM has a performance issue fixed. In MOUSE a Horton Infiltration time issue has been fixed.

MIKE FLOOD hotfix 20-01-2017

This hot-fix speeds up the initialization phase of a simulation involving river components.

MIKE HYDRO hotfix 13-01-2017

Since we installed Service Pack 3 for MIKE 2016 and MIKE HYDRO hotfix 01-12-2016 load calculator doesn’t allow us to use: SOURCES -> TIME DISTRIBUTION -> Distribute according to runoff. We get the error: “cannot distribute to runoff, because different properties of used times series…disable ‘distribute according to runoff’ or fit series used in panel “Catchments” to catchment definition in MIKE HYDRO”. Error doesn’t appear on Mike 2016 without Service Pack and Hotfix. The MIKE HYDRO hotfix 01-12-2016 has been removed from the available lists of hotfixes. This hotfix solves the problem, besides improving the error messaging in case any catchment time series has a different number of time steps.

MIKE 3 hotfix 12-01-2017

This hotfix resolves an issue in MIKE 3 HD FM for the GPU version related to implementation of gates.

MIKE BASIN hotfix 11-01-2017

This hotfix resolves the following issues:

  1. The calculation of the updated LAV curve was numerically unstable when the new zero level is close to the old one for reservoirs type I, II and III. For that reason the update will be postponed to later time steps when the new value is too close to the old one, avoiding these numerical problems.
  2. The routing of sediments had mass errors, resulting on negative values for the virtual sediment on reaches.
  3. Numerical error in the calculation of the new zero level for the sedimentation of the reservoir (levels of current LAV curve were wrongly read as integer instead of doubles).
MIKE HYDRO hotfix 29-12-2016
