Release Information
MIKE FLOOD

Release Note - 2009

Introduction

Welcome to MIKE FLOOD Release 2009.

MIKE FLOOD is a dynamically linked one-dimensional and two-dimensional flood modelling package. 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 a maximum of flexibility by allowing users to model some areas in 2D detail, while other areas can be modelled in 1D.

Hardware Requirements

The recommended minimum hardware requirements are:

Supported Operating Systems: XP Professional (32 and 64 bit), Vista Business (32 and 64 bit)
Processor: 2.0 GHz PC (or higher)
Memory (RAM): 2 GB (or higher)
Hard disk: 40 GB (or higher)
Monitor: SVGA, resolution 1024x768 in 16bit colour
Graphic Card: 32 MB RAM (or higher), 24 bit true colour
Media: CD-ROM/DVD drive, 20 x speed (or higher)
File system: NTFS

Installation^ top

To install MIKE FLOOD, please choose 'MIKE FLOOD' in the 'MIKE BY DHI Setup' dialog that appears when inserting the MIKE software 2009 DVD and then press the 'Install' button.

If you are using MIKE FLOOD with an urban component (MOUSE or MIKE URBAN) please then install these products subsequently.

License File and Dongle^ top

To use MIKE FLOOD in licensed-mode please follow these steps:

  1. Make sure that the provided dongle is attached to the computer (parallel or USB port - for Windows XP Professional x64 Edition USB port only)
  2. The dongle driver is installed automatically during the setup of the program.
  3. The MIKE software license file (DhiLicense.dat) may be retrieved using the Internet. A working Internet connection and a valid e-mail address are required. The license file may be retrieved in two ways:
  • During installation of MIKE software
  • After installation of MIKE software, by launching the License Updater through the start menu
  1. To retrieve your license file during installation of MIKE software, select “Local” when prompted to select the type of License Management, and then select “Internet” and follow the on-screen instructions
  2. To update your license file using the License Updater, simply launch “Start->Programs->MIKE BY DHI 2009->DHI License Updater” and follow the on-screen instructions.
  3. Alternatively, the license file can simply be copied from the supply medium (attachment to e-mail from DHI or CD/DVD/floppy disk) in  \Program Files\DHI\2009\License or Program Files (x86)\DHI\2009\License.

Product Invocation^ top

To start MIKE Flood go to Start -> Programs -> MIKE BY DHI 2009-> MIKE Zero -> MIKE Zero.

This will start the general MIKE Zero interface from which either existing MIKE Flood files can be loaded or new MIKE Flood files created.

Starting MIKE Flood without a DHI configured Software Key and valid license files causes the program to run in Demo mode. If this happens, a message box will inform you during program initialisation. Running in Demo mode, MIKE Flood supplies full access to all editors, input files and editing facilities. However, restrictions apply on which set-ups that can actually be executed as a model simulation.

New features^ top

  • 3-way coupling:
    A new multi-directional coupling has been developed and implemented to allow for a coupling between the river system (MIKE 11), the surface flow component (MIKE 21) and the Urban area modelling component (MIKE URBAN)
  • Linkage line definition using Shape file: Shape-files can now be used to define lateral linkage line between MIKE 11 and MIKE 21
  • Linkage line definition using xyz-file: xyz ascii-files can now be used to define lateral linkage line between MIKE 11 and MIKE 21

Known Defects & Workarounds^ top

 

MIKE FLOOD 2009 Service Pack 1 - May 2009

 

Service Packs includes fixes to inconveniences and errors, minor modifications and features to MIKE FLOOD Release 2009.

SP1 for MIKE Flood includes the following changes:

Module/Type Error/Inconvenience/New feature Status Remarks
MIKE 21 HD The simulation runtime for MIKE FLOOD models using MIKE 21 rectangular grid is significantly improved.
Performance improvement is achieved by restructuring code and no changes to solution algorithms etc. at all. Hence, simulation results will not change from previous versions due to this change.		 Improvement  

 

MIKE FLOOD 2009 Service Pack 2 - June 2009

Service Packs includes fixes to inconveniences and errors, minor modifications and features to MIKE FLOOD Release 2009.

Service Pack 2 (SP2) for MIKE Flood includes changes from previous Service Pack as well as the following changes:

Module/Type Error/Inconvenience/New feature Status Remarks
Seamless plot, output The Seamless plot feature of MIKE Flood (using HPQ-maps in MIKE 11) had the following recognized problems:
  • Maximum values from MIKE 21 not correctly transferred to the mapping routine when producing a 'Max-map' of any item.
  • Bathymetry-values of MIKE 21not correctly presented when loading map in MIKE Animator.
    		•  Solved  

     

    MIKE FLOOD 2009 Service Pack 3 - November 2009

    Service Packs includes fixes to inconveniences and errors, minor modifications and features to MIKE FLOOD Release 2009.

    Service Pack 3 (SP3) for MIKE Flood includes accumulated changes from previous Service Packs as well as the following changes:

    Module/Type Error/Inconvenience/New feature Status Remarks
    MIKE FLOOD Urban                 

    Erroneous check for a DMI module removed in Mouse Engine when coupled to MIKE 11                                                          

    		Solved  
    MIKE FLOOD FM

    Illegal storage error occasionally occurred when starting model simulation for specific combination of input file locations.

    		 Solved  
    MIKE FLOOD AD

    An error has been found for the AD-coupling of MIKE 21 and MIKE 11 if mutliple AD-compoents were simulated. Concentration values for all components were not correctly transferred between the models causing errors in simulation results.

    		 Solved  
    MIKE Flood FM: Link definition using external files Linking MIKE 11 with MIKE 21 using external files (xyz- and shape-files) was not working properly for the FM-model coupling. Solved  
    Lateral linkage elevations

    Elevations of Lateral links have been found occasionally to be determined incorrectly. The error presents it self as linkage elevation being too high locally. The error is caused by an incorrect weighted interpolation routine and hence, at local chainages, it can be observed that the linkage elevation is too high due to an incorrect influence of an upstream MIKE 11 cross section.
    The error will only show only in the following situations:              

    • if MIKE 11 is selected as the source and the bed-level of the upstream cross section is at a higher level than the embankment marker of the cross section at the actual linkage location, or
    • if HGH method is selected as the source and MIKE 11 levels are higher than the MIKE 21 surface levels AND the bed-level of the upstream cross section is at a higher level than the embankment marker of the cross section at the actual linkage location.

    So, most typically, such an error could occur in reaches where distance between cross sections are big and bed slope also significant.
    The error is most typical found by investigating the MFLateral.txt file when analysing the structure linkage elevations, where it will typically be visible as suspicious 'stair-like' elevation profiles.

    		 Solved This correction can potentially change model simulation results locally as structure elevations locally can be lower than in previous versions.

     

    MIKE FLOOD 2009 Service Pack 4 - February 2010

     

    Service Packs includes fixes to inconveniences and errors, minor modifications and features to MIKE FLOOD Release 2009.

    Service Pack 4 (SP4) for MIKE Flood includes accumulated changes from previous Service Packs as well as the following changes:

    Module/Type Error/Inconvenience/New feature Status Remarks
    River/Urban Links MIKE Urban Outlet to MIKE 11 Link; The Water level boundary overwrites the MIKE 11 boundary value, which is not meant to happen. Solved                 
    River/Urban Links Occasionally, the boundary definitions was not applied correctly and no water would appear in the model. Solved  
    MIKE 11 / MIKE 21 FM lateral links An error has been found in the Lateral Links feature of MIKE FLOOD FM (coupling of MIKE 11 and MIKE 21 FM).
    The discharge across lateral links was underestimated in cases where the grid spacing in the MIKE 11 portion was less than the segment length of the linkage line. This may occur if the user has chosen a river dx-max resulting in interpolated grid points at run time.     		Solved Fixed error will in some MIKE Flood FM (River) applications will give significantly different results. A backward compatiliby switch is not available as this is a wrong solution being corrected.
