Release Note 2014

MIKE FLOOD

Introduction


Welcome to MIKE FLOOD Release 2014.

MIKE FLOOD is a flexible user interface framework for dynamic linking of MIKE by DHI's one-dimensional and two-dimensional flood modeling packages. MIKE FLOOD is the integrated flood modelling package for rivers (MIKE 11), overland flow (MIKE 21), and urban drainage (MIKE URBAN's MOUSE engine). This combination ensures maximum flexibility by allowing users to model some areas in 2D detail, while other areas can be modelled in 1D.

In this Release Note you will find information about new features of MIKE FLOOD and what you need to know in order to install and get started with Release 2014.


System requirements


The recommended minimum system requirements are:

Operating systems

Fully supported operating systems *
Windows 7 Professional Service Pack 1 (32 and 64 bit),Windows 8 Pro (64 bit), Windows Server 2008 R2 Standard Service Pack 1 (64 bit). For the latest update please refer to the FAQ.

Non-supported but partially tested operating systems **
Windows XP Professional Service Pack 3 (32 bit), Windows 8 Pro (32 bit), Windows Server 2012 Standard (64 bit). For the latest update please refer to the FAQ.
Processor 2.0 GHz Intel Pentium or higher and compatibles, or equivalents

Media DVD drive compatible with dual-layer DVDs is required for installation
File system NTFS
Software requirements .NET Framework 3.5 SP1 and .NET Framework 4.0 (Full Profile)

* Fully supported operational systems are systems that have been tested in accordance with MIKE by DHI'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 by DHI software products. These operating systems have only undergone very limited testing for the purpose of MIKE by DHI software, but the software and key features are likely to work. Installation of MIKE by DHI software on a non-supported operating system is done so at the user's own risk. The MIKE by DHI 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.

*** MIKE 21 Flow Model FM utilising GPU requires a Nvidia graphics cards with compute capability 2.0 or higher. See https://developer.nvidia.com/cuda-gpus. Please note that some of these graphics cards have varying performance in single compared to double precission calculations.

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 FLOOD, please choose MIKE Zero in the ‘MIKE by DHI Setup’ dialogue box that appears when inserting the MIKE software 2014 DVD 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. Additionally, a ‘MIKE by DHI 2014’ entry is created, which contains icons for various MIKE Zero utilities and links to documentation.


Licence file & dongle

^ top

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

  1. You can retrieve the MIKE by DHI 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 MIKE by DHI software
    • After installation of the MIKE by DHI software, by launching the DHI License Updater through the start menu
  2. To retrieve your licence file during installation of MIKE by DHI 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 "Start -> Programs -> MIKE by DHI 2014 -> 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 in \Program files\DHI\2014\License or Program files(x86)\DHI\2014\License.
  5. After completed installation, you should ensure that your hardware key is attached to the system.

Product invocation

^ top

To start MIKE FLOOD, go to Start -> Programs -> MIKE by DHI 2014 -> MIKE Zero or search for MIKE by DHI 2014 and select ‘MIKE Zero’. Then you can select MIKE FLOOD from within the MIKE Zero Shell.

Starting MIKE FLOOD 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 FLOOD 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 FLOOD consists of new modules, new features and/or corrections to problems or significant inconsistencies discovered in previous releases. Below, please find short descriptions of the most significant news in Release 2014 for MIKE Zero in general and MIKE FLOOD specifically.


Known defects & workarounds

^ top


Fixed issues

^ top

A service pack includes fixes to inconveniences and errors and minor modifications to the official release.

Note: MIKE FLOOD include the coupling between MIKE 21, MIKE 11 and MIKE URBAN and issues fixed for these products individually may be relevant for MIKE FLOOD as well. Some fixes are repeated below, but it is advised to check the individual release notes for all these products in addition.


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 2014 Service Pack 3

 

Module/type

Error/Inconvenience/New feature

Status

MIKE Zero (generic)
  • Bathymetry Editor: Issue with long response time when manipulating raw data and background data
  • Mesh Generator: Automatic placement of polygon marker during import of xyz file could fail and be located at boundary of polygon
  • MIKE Zero shell doesn't work with SP2 for 5 languages
Fixed
Result Viewer New feature: Save Vectors to Shape file
The vector field is exported to a shape file as polylines (with no arrow head).
The polylines include the entire vector field for the current time step and will have the scale as shown in the Result Viewer.
Note: polylines can be displayed by arrow symbols in e.g. ArcMap.

Fixed
Unit Base Group Added new EUM types as well as new EUM units to existing EUM types
Added
ECO Lab
  • Potential problems in ECO Lab templates with nested if-then-else statements with more than two nesting levels

Fixed
Engine MIKE FLOOD Single grid: Correction of low flow link discharge implemented in SP1 has been further refined.
Fixed
Engine MIKE FLOOD FM: An issue has been found in error-handling of the engine which occasionally causes simulations to continue running even though an error has occurred in e.g. the MIKE 11 simulation.
