Release Note 2014

MIKE 21

Introduction


Welcome to MIKE 21 Release 2014. In this Release Note you will find information about new features of MIKE 21, and what you need to know in order to install and get started with Release 2014.

MIKE 21 is the world's leading modelling package for 2D free surface flow, waves, sediment transport and environmental processes. It is the true work horse of estuarine and coastal modelling with a wider range of facilities and modules than any similar package.


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) and Windows Server 2008 R2 Standard Service Pack 1 (64 bit). For the latest update, please refer to the FAQ.

File system NTFS
Software requirements .NET Framework 3.5 SP1 and .NET Framework 4.0 (Full Profile)
Microsoft Internet Explorer 4.0 (or later) is required for network license management (if purchased) as well as for accessing the Online Help

* 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 21, 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 21 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 21, 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 21 from within the MIKE Zero Shell.

Starting MIKE 21 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 21 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.

Fixed issues

^ top

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 2014 Service Pack 3

Module/type

Error/Inconvenience/New feature

Status

MIKE Zero
  • 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

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.
