LITPACK Redesign

Release 2011 includes a complete redesign of LITPACK, the modelling package for coastal sediment transport and morphology. The redesign includes:

• A new user interface
• Common setup file for all LITPACK modules
• Flexible definition of input values (constant/time varying/spatially varying)
• User specification of output parameters
• Graphical view of setup in georeferenced domain
• Additional functionality, e.g. calculation of Q-Alpha curves
• Improved Rose Plot: 3rd item defines duration of event
• Improved Profile Editor: Georeferenced line series data
• Improved Project Map: Line series display included

The redesign is a step towards integration in the coupled MIKE 21 FM.

Cyclone Tool

The MIKE 21 toolbox includes a tool for computing wind and pressure fields generated by a cyclone, hurricane or typhoon.

The old Cyclone Tool uses a parametric model developed in the early 1980s that in some cases overpredicts winds.

In Release 2011, several newer parametric models of the cyclone process have been added.

MIKE 21 SW

The Spectral Wave module includes numerous improvements:

• Significant performance improvement by domain decomposition
• Improved convergence of quasi-steady component
• Output of wave power
• Improved description of structures

MIKE 21/3 FM Improvements

Apart from the significant speed improvements, several other new features are included in Release 2011:

• Dynamic update of bathymetries (for dam/dune breaks, morphological seabed changes)
• Improved description of velocity profiles in river simulations

Particle Tracking and New Oil Spill in FM

Release 2011 also includes an improved Particle Tracking module for the FM series. The module includes added features and larger flexibility in terms of output and functionality.

Now the FM series also includes an oil spill module with the same backbone as the Particle Tracking module.

Mesh Generator Enhancements

The new version of the Mesh Generator tool includes several major enhancements including:

• Handling of large scatter data,
• Performance improvement for editing and interpolation in large scatter data sets, and
• Prioritisation of scatter data
