Explore the impact of vessel propeller wash on mud resuspension 
The Mud Transport module now provides valuable insights into sediment dynamics in high-traffic marine areas. The Nearfield model offers an embedded sub-model for analysing integrated jet flow and bed impact, while the Farfield model integrates MIKE 3 FM Hydrodynamic and Mud Transport functionalities. With fully decoupled models and a new, faster solution, this module enhances efficiency in understanding and managing mud resuspension effects.

Enhanced coastal profile interpolation for accurate wave progression analysis
LITPACK now offers a new option to specify profile locations along the coastline by origin, selected from a list. This enhancement improves the accuracy of wave progression calculations toward the breaking point using interpolated profiles. It also integrates interpolation between wave and current forcings, enabling a more comprehensive analysis of coastal dynamics.

Perform high-end computation and MPI parallelisation
MIKE 21 Spectral Waves is based on a flexible mesh, multiple core optimised run engine (Linux compilation also available).

Benefit from significant enhancements to the MIKE Zero Data Extraction FM Tool 
The tool now delivers improved performance through OpenMP parallelisation, enabling faster processing. Input data files can be easily viewed and validated, while output file selection has been streamlined to align with MIKE 21/3 input editors. Bathymetry can now be displayed in Geographical View, enhancing spatial understanding. Users can save 2D and 3D structured overlays as DFSU files across all modules (HD, TR, ST, MT, EL, PT), and horizontal plane outputs are now available for '3D' field types in all modules.

Streamline post-processing with miscellaneous enhancements to the MIKE Zero Data Viewer tool
The tool now allows users to reproject mesh files directly within Data Viewer, simplifying workflows. Polygon selection areas can be saved and loaded to streamline manual post-processing, and the area of selected elements within a polygon can be viewed for increased efficiency. Time series point locations can also be saved and loaded, complemented by additional visual improvements. Transect visualisation has been significantly enhanced to provide clearer insights.

New additions to the MIKE Zero Toolbox Statistics Group
The DFSU Vertical Statistics tool has been introduced, replacing the hidden DataVerticalAveragingFM.exe. It supports calculations for maximum, minimum, and mean values, though some non-essential functions have been removed, making it not fully backward compatible. Additionally, the DFSU Statistics tool merges the capabilities of DataStatisticsFM.exe and DataExceedanceFM.exe. This tool offers calculations for maximum, minimum, mean, standard deviation, exceedance, and percentiles, with the percentile feature being entirely new. However, it is not backward compatible for exceedance calculations. Note that the hidden tool DataExceedanceFM.exe will be retired in MIKE Zero 2025.

New Split View Comparison in MIKE Zero Results Reviewer
The Results Reviewer now features a slider-based 'Split View Compare Files' function, allowing you to compare two files side-by-side for easier analysis and better comparison of results.

Experience enhanced stability for both higher-order and low-order schemes, particularly in regions involving flooding and drying, with notable advantages for three-dimensional simulations. The fast low-order scheme has undergone substantial enhancements in accuracy and stability, especially in areas with steep gradients. Consequently, velocities along riverbanks and underwater channels now exhibit better alignment with the more accurate higher-order scheme. Furthermore, the performance of GPU solvers has been optimised for simulations that incorporate infrastructure features and flow-dependent bed resistance.

The accuracy of our advection-dispersion scheme has been improved with an upgraded discretisation of the diffusion terms.

Coastal and marine modellers – run faster, more accurate FM simulations in more applications with improved numerics. Plus, avoid freak (unnatural) velocities and numerical noise, particularly when modelling steep gradients such as riverbanks and shelf seas.

Users can now calculate excess temperature in desalination plants, more accurately assess flooding with an H4Inundation output on line series, and even run degree-based map projections thanks to the removal of LONG/LAT dependency in the FM engine(s). Experience faster GPU acceleration, particularly during the initialisation phase for shapefiles that include thousands of polygons.

Salt marsh and mangrove vegetation, which cover ~19% of our global coastline, are paramount in helping to reduce climate change-related risks along the coastline. Particularly when used in combination with other natural or man-made coastal defences, belts of coastal vegetation can help reduce damage and associated costs from waves, intense storms, tsunamis, erosion, and sea-level rise.

To better support coastal zone management planning and coastal defence initiatives, MIKE 21 Flow Model FM, MIKE 3 Flow Model FM and MIKE 3 Wave FM models can be used for a variety of vegetation – from rigid plants like mangroves to flexible plants such as salt marsh cover. In addition, MIKE 21 Spectral Wave FM also includes two new dissipation models for rigid plants: a multi-layered approach for the fully spectral formulation and directionally decoupled parametric formulation and a single-layered approach for the fully spectral formulation.

MIKE 3 Flow Model FM users now have access to a k-Omega turbulence model with wall functions to model vortices and vortex shedding around vertical structures such as slender piles. When coupled with a MIKE 21/3 Mud Transport or a MIKE 21/3 Sand Transport model, you can more accurately predict scour around structures. Watch video
