Release Note 2016

MIKE FLOOD

Introduction

Welcome to MIKE FLOOD Release 2016. 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 2016.

MIKE FLOOD is a flexible user interface framework for dynamic linking of MIKE's one-dimensional and two-dimensional flood modeling packages. MIKE FLOOD is the integrated flood modelling package for rivers (MIKE HYDRO River and MIKE 11), overland flow (MIKE 21), and urban drainage (MIKE URBAN). This combination ensures maximum flexibility by allowing users to model some areas in 2D detail, while other areas can be modelled in 1D, and hence the perfect modelling tool to apply for a wide range of flood related application including Coastal flooding, Urban flooding and Riverine flooding.

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 8.1 Pro (64 bit), Windows 10 Pro (64 bit) and Windows Server 2012 R2 Standard (64 bit).

Non-supported but partially tested operating systems **
Windows 8.1 Pro (32 bit), Windows 10 Pro (32 bit) and Windows Server 2008 R2 Standard Service Pack 1 (64 bit).

* 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.

*** 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 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 FLOOD 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

^ top

Launch 'MIKE Zero' from the Windows Start menu. 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 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 FLOOD specifically and for MIKE FLOOD 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

Parallelisation FM

New parallelisation parameters: Number of subdomains and Number of threads per subdomain and a new Use GPU checkbox if supported GPUs are detected

  • Setting Number of subdomains=1 corresponds to using OpenMP in previous versions
  • Per default the Number of subdomains is set equal to the number of cores on the computer.
    This setting can be changed under User settings.
  • Selecting the Use GPU checkbox will present a list of all supported GPUs.
    Specify which GPUs to use for simulation using this list.
Result Viewer

Option to export velocity vectors to a shape file

Time Series Comparator

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

Data Extraction FM

New option to extract flow discharge through a cross-section

MIKE Zero Toolbox
New GIS tool, Shp2Xyz, to extract point, polyline and polygon information from shape files
MIKE Zero Toolbox
New toolbox enabling users to create a Hotstart file for MIKE 21 single grid from existing results files
MIKE FLOOD
Multiple GPU card in FM simulation engines

MIKE FLOOD Flexible Mesh can utilise multiple GPU cards in the local computer for improved computational performance. Uniquely, MIKE FLOOD is capable of simulating coupled 1D-2D simulations using the GPU solution.

MIKE HYDRO River added as river modelling component
Release 2016 introduce MIKE HYDRO River as our new generation river modelling package, which over time will replace our existing river modelling package; MIKE 11. MIKE FLOOD has been extended with an option to couple with a MIKE HYDRO River model as well. It is therefore possible to use either MIKE 11 or MIKE HYDRO River as the river modelling option in a MIKE FLOOD model in release 2016.
Coupling using MIKE 1D engine
The new generation of our 1-dimensional simulation kernel; MIKE1D provides improved simulation performance compared to the classic MIKE 11 engine and it is therefore now possible to activate the MIKE1D engine through the MIKE FLOOD editor when coupling to a MIKE 11 simulation file. MIKE HYDRO River utilise the MIKE 1D only and the coupled simulations using MIKE HYDRO River will therefore always utilize MIKE1D in simulations.
Flood Screening Tool

NEW simple yet faster Cartesian grid based MIKE 21 solver designed for inland flooding applications.
The Flood Screening Tool (FST) option introduces an additional numerical solver for the grid-based MIKE 21, which can also be applied in connection with MIKE FLOOD simulations.
A diffusive wave approach brings a simpler and thus faster numerical solution that enables even more rapid flood screening outputs.

Module/type

Error/Inconvenience/New feature

Status

MIKE FLOOD Engine
When using the MIKE 1D engine for the 1D models, MIKE FLOOD now also creates the HTML simulation summary files for the 1D simulations, containing the volume balance summary.
Added
MIKE FLOOD Engine
Lateral Inflows through lateral links are now also saved in the result file, when using the MIKE 1D engine. Lateral Inflows are provided separately for the left and the right bank, and are automatically stored in the default *.res1d result file. 
Added
MOUSE Engine
When a MIKE URBAN pipe is coupled to a river, the MOUSE engine requires that the pipe is digitised from the pipe network towards the river. If this is not the case, MOUSE now gives an error during the initialization of the simulation.
Added
MIKE FLOOD Engine
Unexpected errors were sometimes obtained for hydrodynamic or advection-dispersion simulations, when coupling with the MIKE 1D engine. These errors have now been fixed.
Fixed
MIKE FLOOD Engine
Lateral links with the MIKE 1D engine now use an improved solution to avoid mass balance errors through the couplings.
Fixed
Flood Modelling Toolbox
Correction of a wrong validation error “The 2D result dfsu file’s timesteps don’t overlap that of 1D result file” for the Flood Mapping tool that prevented the engine to start.
Fixed
MIKE FLOOD Engine
When coupling MIKE 21 FM to MIKE URBAN with the MOUSE engine, an improved solution has been implemented to avoid mass errors through the couplings.
Fixed
MIKE FLOOD Engine
When coupling MIKE URBAN with MIKE 21, and when using the multi-cell overland solver, a volume of water was transferred to MIKE 21 at the beginning of the simulation even for low flow conditions.
Fixed
