Software requirements .NET Framework 3.5 SP1 and .NET Framework 4.0 (Full Profile)

* Fully supported operating systems are systems that have been tested in accordance with MIKE's Quality Assurance procedures and where warranty and software maintenance agreement conditions apply.

** Non-supported but partially tested operating systems are systems, which are not officially supported by the MIKE software products. These operating systems have only undergone very limited testing for the purpose of MIKE software, but the software and key features are likely to work. Installation of MIKE software on a non-supported operating system is done so at the user's own risk. The MIKE software warranty and software maintenance agreement conditions do not apply for unsupported operating systems and DHI is under no obligation to provide assistance or troubleshooting for cases where the software is being used on a non-supported operating system.

Please note that single user installations are not allowed on server operating systems. Also, when running a fully supported operating system as a 'guest operating system' on a virtualisation platform, it is automatically downgraded to a non-supported operating system under the conditions provided above.

Installation

^ top

To install MIKE 11, please choose MIKE Zero in the ‘MIKE Setup’ dialogue box that appears when inserting the MIKE software 2016 USB and clicking the Setup.exe or executing the Setup.exe file from the downloaded installation files. Press the ‘Install’ button to begin installation.

The setup programme will automatically install all necessary files and folders on your computer.

Licence file and dongle

^ top

To use MIKE 11 in licenced mode, please follow these steps:

  1. You can retrieve the MIKE software licence file (DhiLicense.dat) via the Internet. This requires a working Internet connection and a valid e-mail address. The licence file can be retrieved in two ways:
    • During installation of the MIKE software
    • After installation of the MIKE software, by launching the DHI License Updater through the Windows Start menu
  2. To retrieve your licence file during installation of MIKE software, select ‘Local’ when prompted to ‘Select license type’. In the following dialogue box, select ‘Internet’. At the end of the installation process, you will be prompted to insert your DHI dongle. Insert the dongle and follow the on-screen instructions.
  3. To update your licence file using the License Updater, simply launch the DHI License Updater and follow the on-screen instructions. On Windows 8, search for DHI License Updater.
  4. Alternatively, the licence file can simply be copied to the \Program files\DHI\2016\License or Program files(x86)\DHI\2016\License directory.
  5. After completed installation, you should ensure that your hardware key is attached to the system.

Product invocation

Launch MIKE Zero from the Windows Start menu. Then you can select MIKE 11 from within the MIKE Zero Shell.

Starting MIKE 11 without a DHI configured hardware key and valid licence files will cause the programme to run in demo mode. If this happens, a message box will inform you during programme initialisation. When running in demo mode, MIKE 11 supplies full access to all editors, computational engines and editing facilities. However, restrictions apply to the setups that can actually be executed as a model simulation.

New features

^ top

Every new release of MIKE 11 consists of new modules, new features, or corrections to problems or significant inconsistencies discovered in previous releases. Below, please find short descriptions of the most significant news in Release 2016 for MIKE 11 specifically and for MIKE 11 related options in the general MIKE Zero framework.

MIKE Zero

Module/type

New feature

Start Page

The MIKE Zero start page has been extended with an extra window that provides you with a faster access to resources and information

Time Series Comparator

New tool that can compare two time series files, compute some performance measures and produce relevant comparison plots

MIKE 11
MIKE HYDRO River

Significant development efforts have been put into development of our future Graphical User Interface for river modelling with MIKE software. The successor to the current multiple editor based Graphical User Interface of MIKE 11 is MIKE HYDRO River.

Consequently, no new developments have been implemented in the classic MIKE 11 package for Release 2016.

MIKE HYDRO River was originally introduced in release 2014, primarily with the intension to present the new generation user interface for river modelling with MIKE to MIKE 11 users.
Release 2016 will introduce MIKE HYDRO River as a full-featured model package, fully capable of being applied in river modelling projects from this release.
For content description of MIKE HYDRO River, please see Release Notes for MIKE HYDRO.

Users of MIKE 11 HD with a valid SMA will automatically obtain a license for MIKE HYDRO River in connection with the upgrade to Release 2016 and license files will therefore include both MIKE 11 and MIKE HYDRO River modules. Hence, it is also possible to utilize the new, modern Graphical User Interface for model build for existing MIKE 11 users.

MIKE 1D engine

The MIKE 1D simulation engine has been significantly extended with new features and add-on modules for use in MIKE 11 but primarily for use in connection with MIKE HYDRO River simulations, where MIKE 1D engine is the only simulation engine available
For more details on MIKE 1D please refer to separate documentation on MIKE 1D.

Future of MIKE 11
As MIKE HYDRO River is the future MIKE package for 1-D river modelling, an initial announcement is provided here that MIKE 11 is planned to be decommitted as a MIKE product at a time in future. The time for decommitting MIKE 11 has not yet been decided, but the decision will naturally be cautious and  announcements will be made in due time to our users on the decommittment schedule.

A service pack includes fixes to inconveniences and errors and minor modifications to the official release.
Please note that the service packs are accumulative, i.e. corrections and fixes released with a previous service pack are included in the newest service pack as well. 

Release 2016 Service Pack 3

Module/type

Error/Inconvenience/New feature

Status

License
A problem when running MIKE 11 simulations from a prompt when using the internet license option has been corrected.
Fixed
MIKE 1D engine, Hydrodynamic module
When working with control structures, the control strategy ID saved in the result file was wrong for the 'Unchanged' control rule.
Fixed
MIKE 1D engine, Hydrodynamic module
In some cases the additional storage defined on link channels was not properly handled.
Fixed
MIKE 1D engine, Hydrodynamic module
In some cases, the simulation couldn’t start with a Dambreak structure, due to an unexpected error during the initialisation of the simulation.
Fixed
MIKE 1D engine, Hydrodynamic module
The additional output item "Discharge on h-points" contained wrong values.
Fixed
MIKE 1D engine, Rainfall Runoff module
Zone numbers are now provided in the result variables from a NAM simulation using elevation zones.
Added
Sediment transport module
Service Pack 2 included a slightly revised formulation in the scaling of graded sediment transport at fixed bed locations. An option has now been added to revert to the original formulation applied prior to Service Pack 2.
Added
MIKE 1D engine, Data Assimilation module

The behavior of the ‘Include error forecast’ checkmark in DA simulations has been changed. Activating the checkmark now enables full updating in both hindcast and forecast period, while de-activating the checkmark now de-activates the updating station completely.

Added
MIKE 1D engine, Data Assimilation module
When performing simulations with Data Assimilation, the simulation stopped if observed data were not available for the whole hindcast period. In such situations, the simulation will now continue and will start the error prediction when observed data are not available.
Fixed
MIKE 1D engine, Data Assimilation module
When performing simulations with Data Assimilation, with the weighting function, when an error prediction’s equation used a constant Parameter, the Parameter value was not properly transferred to the engine, leading to a wrong error prediction.
Fixed
MIKE 11 Classic engine, Data Assimilation module
A problem with a sensitive and potentially unstable solution when updating at locations in branches with negative flow direction has been fixed.
Fixed
MIKE 11 Classic engine, Data Assimilation module
An error in control strategy number saved to results file during Data assimilation simulations has been fixed.
Fixed
Release 2016 Service Pack 2

Module/type

Error/Inconvenience/New feature

Status

MIKE 11 Sediment Transport
Lateral sediment boundaries for adding or subtracting sediments at point locations was applied with a wrong sign in river branches defined with 'negative flow direction'. Fixed such that positive values for sediment lateral boundary will add sediments and negative values will extract sediments from the river.
Fixed
MIKE 1D engine; Rainfall Runoff
The mass balance calculation in the HTML summary for the URBAN B catchment was wrong.
Fixed
MIKE 11 Hydrodynamics

Release 2016 introduced model validation check, which unfortunately resulted in a misleading warning message for some model-setups: "Warning No 162:Branch connections are made to 'river' : 'chainage' meter, which is connected to another node. This is not allowed. Please reconnect the branches."

This error could appear in setups which did not have any problems in branch connections.

Fixed
MIKE 1D engine;  Rainfall Runoff

In UHM model simulation the MIKE1D rainfall runoff module always use the value of the 'RR timestep multiplier' - regardless if it is a stand-alone RR or a coupled HD-RR simulation, which was wrong.

The RR time step multiplier should only be considered when running HD and RR simulations in parallel.

Fixed
MIKE 1D engine; Hydrodynamics
An error has been identified when a hydraulic structure is defined at a location where a cross sections is also defined or when a structure geometry is defined using a cross section from the xns11-file. Result was much reduced flow capacity of the structure and hence a high backwater in some cases.
Fixed
MIKE 11 Data Assimilation

Some models using DA-module have experienced problems with simulation results using hotstart as initial condition.

An option enabling the user to activate or de-activate reading of DA-values from a hotstart file has therefore been introduced. The switch has been introduced in the MIKE11.Ini file (parameter-name: USE_CORRECTION_VALUES_FROM_HOTSTART).

Fixed
MIKE 11 Network editor,  Culverts
In the Culverts dialog, when calculating Q/h-relations for an Open culvert, the number of Q/h-relations was accidently divided by two every time a new calculation was made and the network file updated. Hence, a number of re-calculations of Q/h-relations could result in only two set of data being saved ultimately.
Fixed
MIKE 11 Sediment Transport
Division by zero obtained in model setups using Van Rijn sediment transport model when defining grain size standard variation variable to zero. This is not allowed and will result in a zero mean-diameter in simulation and hence a crash. An error-message has been included to inform prior to model simulation.
Fixed

Module/type

Error/Inconvenience/New feature

Status

MIKE 11 Data Assimilation

Release 2016 unfortunately introduced an error in the Discharge updating option, causing models applying  discharge updating at stations to run without any updating at these stations during forecast simulations.
Fixed

MIKE 11 Rainfall Runoff

Differences obtained when comparing simulation results from a stand-alone simulation and a coupled HD-RR simulation for the UHM runoff method. Differences can occur when RR timestep multiplier is  defined with a value larger than one  in the coupled HD-RR simulation.
Fixed

MIKE 1D engine

Control structures with gate level operations did not take structures sill level in to account as absolute minimum level for gate operation.
Fixed
Release 2016

Module/type

Error/Inconvenience/New feature

Status

MIKE 11 AD

Advection-Dispersion: Link-channels in MIKE 11 has previously been targeting HD-simulations only. These have now been further developed to also enable the usage correctly in connection with AD-simulations.

Fixed
MIKE 11 ST

Graded Sediment transport applied in connection with the non-erodible layer option have been causing wrong results in some applications when all bed material had been eroded.
