Our ecological modelling software, MIKE ECO Lab, will be used in a new project with the aim to develop an advanced set of dynamic modelling tools, which will be the official tools for marine water planning in Denmark in the coming years.

The project is initiated as a collaboration between DHI and Danish Centre for Environment and Energy (DCE). The project will develop and apply ecosystem models by using our MIKE by DHI software, MIKE ECO Lab, and addressing the governing coastal processes and ecosystem services such as sediment processes, sea grass, algal growth and oxygen depletion.

Product news

Previews of MIKE by DHI release

Approximately once a year, we release a new version of MIKE by DHI software - and this year is no exception. We would like to disclose a preview, especially for our newsletter readers, of some of the new and exciting features to be released in December. We hope these new features will improve your experience with our software products, regarding usability, productivity as well as enhanced applications.

New possibilities of including moving objects in your animations

Software news

Ever wanted to add moving objects to your animations? This is possible with Release 2014.

In the September issue of this newsletter, we included a preview of new features in MIKE Animator Plus in Release 2014. In this issue, we would like to show you an example of the possibilities of this new development.

With MIKE Animator Plus, you can create visual animations to present you model results – and as something new, you will be able to include visualisation of solids. Through the inclusion of solids, you can improve your animations significantly by enhancing realism and recognition of locations, for example by including fixed elements like buildings and dams or moving elements like ships. Release 2014 will support the placement of solids inside the model domain and allow them to move, which means that a ship can be sailing as part of the animation.

MIKE HYDRO Basin: Global prioritisation of water users

Software news

MIKE HYDRO Basin is our new generation of integrated river basin analysis software for water resources planning and management.

MIKE HYDRO Basin was introduced with the current release 2012, containing a large number of features relevant for integrated river basin management applications. Developments continue for MIKE HYDRO Basin and the new release will introduce another very interesting new feature to modellers of river basin water allocation schemes and resources management; Global Prioritisation.

With this new feature, it is now possible to include a user defined prioritisation of water users within the basin model - regardless of their geographical location within the basin. Thus, it highly increases the applicability of MIKE HYDRO Basin for specific types of water resources management applications.

The global prioritisation of water users are defined through ‘Ranking’ number definitions, where water consumers are assigned an individual ranking number. The ranking numbers are used during simulation to prioritise consumers, in case of water shortage, in order to accommodate the water demands for these - taking into account that some users have a higher priority than others.

Mesh Generation: A new tool for creating flexible meshes from dfs2 files and other sources

Software news

The combination of high flexibility of flexible meshes (FM) and impressive performance improvements, introduced in the latest releases of MIKE by DHI, make the use of FM versions of MIKE 21, MIKE 3 and MIKE FLOOD even more attractive. Improvements in recent releases include, amongst others, the introduction of shared memory based parallelisation, porting of simulation engines to LINUX and, in Release 2014, supporting Graphical Processing Units (GPUs) for MIKE 21 HD FM.

In order to assist those, who want to transfer existing models or bathymetries into the FM system, Release 2014 will contain a new tool, aimed to convert bathymetries in other formats into FM format.

The new Mesh Converter is included in the MIKE Zero Toolbox and supports DHI’s own format from the ‘classic’ modelling series, dfs2 as well as some external formats (ADCIRC, SMS, TUFLOW). The process is quick and easy and produces an equal bathymetry in FM format, which can then be modified using all the existing editing facilities of MIKE Zero’s Mesh Generator.

New features in FEFLOW 6.2

FEFLOW 6.2 offers a number of new features to enhance your groundwater modelling work.

Software news

Groundwater age calculation in FEFLOW 6.2
Groundwater Age is a new type of problem class, similar to mass or heat transport. With this, many questions can be easily answered, such as:

  • How long is the average underground travel time of water pumped at a well?
  • What‘s the percentage of bank filtration at the supply wells?
  • What‘s the age and remaining travel time of groundwater at a certain location?

New storage capture/release component in FEFLOW 6.2
Storage Capture/Release is a new component in the Rate Budget and Period Budget Panels for flow and transport in FEFLOW 6.2. With this new component, you can clearly separate storage change and solution error in transient models.

Increased performance with new MIKE 1D features in MIKE URBAN

In 2012, we introduced a new generic 1D numerical engine for MIKE by DHI products. With the upcoming release of MIKE URBAN 2014, a number of new features for MIKE 1D will be available such as:

  • coupling to MIKE SHE
  • options for Advection-Dispersion modelling
  • result presentation in MIKE URBAN
  • and many more…

MIKE 1D is parallelised and makes use of multicore PCs, which means that most users will experience higher modelling performance. Now is the time to start using MIKE 1D in your new modelling projects!

Strengthening wastewater modelling projects with new features in WEST 2014

Our WEST software package, for modelling wastewater treatment plants, has quickly established itself as an important product in the MIKE by DHI family with a growing number of users all over the world. Release 2014 includes several important new features, including:

  • New Report Generator, which enables the user to automatically create reports containing graphs and data pertaining to a project in a variety of formats including: project information, plant layout, plots and tables.
  • Integrated urban water system (IUWS) libraries, making WEST a powerful tool for identifying synergies and to globally optimise the wastewater system performance on a catchment scale.

Inclusion of plant wide model (PWM) in the WEST 2014 model library

We are also pleased to inform you that Release 2014 of WEST will include a plant wide model (PWM) for simulating nutrient removal activated sludge systems.

The plant wide model, ‘PWM_SA’, is a three phase model for the simulation of nutrient removal activated sludge systems coupled with the anaerobic (organisms independent of oxygen), aerobic (organisms dependent on oxygen) and anoxic-aerobic digestion of sewage sludge. This includes waste activated sludge produced by biological excess phosphorus removal plants. The model is based on strict material mass balance and is prepared by linking:

  1. a variation of ASM2 for activated sludge nitrogen and phosphorus removal and aerobic or anoxic–aerobic digestion
  2. a variation of the UCT anaerobic digestion model.

The main extensions to the original models are through their integration within a three phase mixed weak acid/base chemical and physical processes models of the inorganic carbon, ammonia, acetate, propionate and phosphate systems.

The plant wide model is developed jointly by our WEST Development Centres, the Universities of Cape Town (UCT) and kwaZulu-Natal in South Africa.

Application examples

Saving resources and improving wastewater treatment performance at the same time

MIKE by DHI case story

Click here to read the full case story.

Québec City in Canada invested in chemical enhancement of its wastewater treatment plant (WWTP) by installing alum addition in its existing primary clarification process. Despite promising results in preliminary tests, the designed chemical dosage seemed to over-perform causing chemical supply costs to be unsustainably high. In order to reduce chemical use while keeping good effluent quality, the city initiated a study to gain a better understanding of the dynamic effects of alum addition in primary treatment. The aim was to design an appropriate automatic controller able to maintain performance at reduced resources. The city applied a model-based approach using our WEST software, which allowed it to test different control strategies and settings in a cost-effective way without jeopardising operational stability and performance.
