To install MIKE 3, please choose 'MIKE 3' in the 'MIKE BY DHI Setup' dialog that appears when inserting the MIKE software 2009 DVD and then press the 'Install' button.

The setup program automatically installs all necessary MIKE 3 files and folders on your PC. Additionally, a 'MIKE Zero' group is created, ccontaining the icon for MIKE Zero and group entries for Documentation, Release Notes and Tools.

License File and Dongle^ top

To use MIKE 3 in licensed-mode please follow these steps:

Make sure that the provided dongle is attached to the computer (parallel or USB port - for Windows XP Professional x64 Edition USB port only)
The dongle driver is installed automatically during the setup of the program
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 the MIKE software, by launching the License Updater through the start menu

To retrieve your license file during installation of the MIKE software, select “Local” when prompted to select the type of License Management, and then select “Internet” and follow the on-screen instructions
To update your license file using the DHI License Updater, simply launch “Start->Programs->MIKE by DHI 2009 ->DHI License Updater” and follow the on-screen instructions.
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 3, select the 'MIKE Zero' icon under the 'MIKE Zero' group, or go to
Start -> Programs -> MIKE by DHI 2009 -> MIKE Zero and select 'MIKE Zero'.

Starting MIKE 3 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 initialization. Running in Demo mode, MIKE 3 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.

Module/Type	Error/Inconvenience/New feature	Status	Remarks
MIKE 21/3 OS	Error in license check of OS module	Fixed

MIKE 3 2009 Service Pack 2 - June 2009

Service Pack 2 (SP2) includes fixes to inconveniences and errors, minor modifications and features to MIKE 3 Release 2009 and SP1. Please note the following changes in SP2:

Module/Type	Error/Inconvenience/New feature	Status	Remarks
MIKE 21/3 OS	The oil spill templates has been revised to correct units and remove redundant variables. Note that previously made Oil Spill setups should be revised to ensure compability with the new modified templates.	Fixed
MIKE 3 FM	When using a dfs2 data file for boundary data in MIKE 3 FM (all modules) the origo i the vertical direction is not set correct.	Fixed
MIKE 3 HD FM	Error in MIKE 3 Flow Model FM in connection with ice.	Fixed
MZToolbox	GIS Tools, Mike2Txt: Extracted xyz coordinates were dislocated from cell center position.	Fixed
Plot Composer	DFSU Plot: Displayed XYZ points using the Image Manager was positioned incorrectly.	Fixed

MIKE 3 2009 Service Pack 3 - November 2009

Service Pack 3 (SP3) includes fixes to inconveniences and errors, minor modifications and features to MIKE 3 Release 2009 and SP2. Please note the following changes in SP3:

Module/Type	Error/Inconvenience/New feature	Status	Remarks
MIKE Zero	Re-design of file name appearence in various dialogs - the file path only appears in fly-by text Data Extraction FM: Error in interpolation of wave directions when direction interval cross 0 degrees Misc. issues regarding shape file layers in editors and viewers Error in editing origo in dfs3 data files using the Grid Series Editor and Data Utility tool	Modified/Fixed
MIKE 3 HD FM	New approach for the entropy fix correction used in the Riemann solver when higher order scheme is used for the space discretization. This correction can have a significant effect on the results - especially for river applications. The previous approach could cause unphysical numerical diffusion. It is possible run the simulation using the previous approach with a special setting in the setup file. Error in calculation of Richards damping Correction of procedure for calculation of the horizontal gradient of the velocity field used for horizontal eddy viscosity. At the bed a full slip approach is used instead of a no slip approach. This correction can have a significant effect on the results - especially for coarse grids and for river applications. It is possible run the simulation using the previous approach with a special setting in the setup file. Error in determination of vertical profile using combined sigma/z-level Error in connection with velocity, flux or discharge boundaries when combined sigma/z-level formulation is used. Small deviation could occur if the simulation were performed on multi-core computers.	Fixed
MIKE 3 ST FM	Error in interpolation of wave directions in spatial domain with input data of dfs2 and dfs1 data files when direction interval cross 0 degrees	Fixed
MIKE 3 MT FM	Error in interpolation of wave directions in spatial domain with input data of dfs2 and dfs1 data files when direction interval cross 0 degrees	Fixed

MIKE 3 MT FM	The layer thickness used in the process calculation is not correct in the bottom layer using conbined sigma/z-lavel discretization	Fixed
MIKE 21/3 PT	Error in calculation of settling velocity when more than one class is used Error in calculation of drift profile for 3D simulation	Fixed
MIKE 21/3 OS Template	Water viscosity was wrongly specified as kinematic viscosity [m^2/s] instead of dynamic viscosity [Pa s] Particle size was defined by 'grain diameter [mm]', but needs to be defined by 'average grain radius [m]' The wax and asphaltene fraction was assumed to have an initial mass of 10kg each. Now the given fractions are used. This may influence the emulsion behaviour.	Fixed/Modified
MIKE 21/3 OS	An error caused the GUI not to accept some time-varying data items Concentration calculations used fixed water depth instead of current water depth Sources can now be defined in two ways using the new flux interpretation option: Off: Source defined by individual particle value. I.e. increasing the number of particles will increase the magnitude of the total source On: Source defined by total source value. I.e. increasing the number of particles will decrease the value for the individual particle	Fixed New Feature
