Release Note 2014
Welcome to WEST Release 2014. In this Release Note you will find information about new features of WEST, and what you need to know in order to install and get started with Release 2014.
WEST 2014 is the third release of the re-designed and re-engineered version of WEST, the powerful and user-friendly tool for dynamic modelling and simulation of wastewater treatment plants (WWTP). The extensive state-of-the art model library of WEST enables one to model and evaluate almost any kind of modern WWTP. WEST 2014 comes in three different flavors:
- WESTforDESIGN: Validation of design options and evaluation of different plant layouts under dynamic conditions
- WESTforOPERATORS: Simulation of short term (e.g. storm events) and long term (e.g. consistent nutrient removal) evaluations of WWTPs
- WESTforOPTIMIZATION: Optimisation of the (waste)water treatment processes
Projects created with WEST 2011/2012 can be opened in WEST 2014 without any further ado. Projects created in WEST 3.7.6 must first be converted to 2014 format through the WEST3 Conversion Tool, which is included in the WEST 2014 installation. The WEST3 Conversion Tool can either be lauched from WEST 2014 through the Tools Menu, or it can be started separately through the corresponding Windows Start Menu entry. Projects created with WEST versions prior to 3.7.6 are not supported. It is also not possible to open WEST 2014 projects in WEST 2011/2012.
The recommended minimum system requirements are:
Fully supported operating systems *
Windows XP Professional Service Pack 3 (32 bit), Windows 8 Pro (32 bit) and Windows Server 2012 Standard (64 bit). For the latest update, please refer to the FAQ.

* 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.
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.
To install WEST, please choose WEST 2014 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.
To use WEST in licenced mode, please follow these steps:
- 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
To start WEST, go to Start -> Programs -> MIKE by DHI 2014 -> WEST or search for MIKE by DHI 2014 and select WEST.
For general support, please refer to our FAQ.

Every new release of WEST consists of new modules, new features and/or corrections to problems or significant inconsistencies discovered in previous releases. Please find short descriptions of the most significant new and exiting features in Release 2014 below. For further information, please refer to the relevant User Guide.
PWM Model Library Category
A new category named PWM_SA was added to the WESTforOPTIMIZATION library, which implements a plant-wide model (PWM) for simulating nutrient removal activated sludge systems. The PWM_SA is a 3-phase model for the simulation of nutrient removal activated sludge systems coupled with the anaerobic, aerobic 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 and 2) a variation of the University of Cape Town’s (UCT) anaerobic digestion model. The main extensions to the original models are through their integration within a 3-phase mixed weak acid/base chemical and physical processes models of the inorganic carbon, ammonia, acetate, propionate and phosphate systems. The plant-wide model was developed jointly by our WEST Development Centers, the Universities of Cape Town and kwaZulu-Natal (South Africa).
IUWS Model Library
A new suite of models for Integrated Urban Water System (IUWS) has been added to the WESTforOPTIMIZATION library. The IUWS library contains a Palette (and the corresponding models) that can be used to build an integrated model of the Urban System consisting of the catchment area (models: variants of "Catchment"), the sewer network (models for pipes and tanks: variants of "Tank"; models for Combined Sewer Overflows: variants of "CSO"), the WWTP (the standard WEST.WWTP models) and the river (models: variants of "River"). Relevant "connectors", sensors and controllers models are also available. A dedicated Block Library has been created. The IUWS library contains only one Category, ASM2dMod (and, by default, only the corresponding Instance): the IUWS models are not fit to be used with any other Model Category. In WEST 2014, the IUWS library is supplied "as is", i.e. with no model documentation. The library was originally developed by Ghent University (Belgium), Waterways (Italy) and Waterschap De Dommel (Netherlands). TBC
Influent / Effluent Tools
The Influent / Effluent Tools have been entirely redesigned and reimplemented. Settings are now made persistent and can be visualised and modified at any time. Also, the tools are no longer implemented as modal windows, but rather as dockable windows. Note: existing (de)fractionation layouts that use references to (de)-fractionation variables in weights will have to be manually adapted: all "_this" suffixes should be removed (".this" should remain however).
Input / Output Tools
The Input / Output Tools have been entirely redesigned and reimplemented. Settings are now made persistent and can be visualised and modified at any time. Also, the tools are no longer implemented as modal windows, but rather as dockable windows.
Dialogue for Top-level Interface Variables
Top-level Interface Variables can now be managed through a dedicated modal dialogue, which can be popped up through the layout's context menu.
Block Library Setup
A new dialogue available through the main menu allows for changing the block library and/or instance for an already existing project. The dialogue also allows for modifying - at the level of the project - one or more model library instance settings (cf. defines).
Organising I/O Sheets
The content (panes) of I/O sheets can be reorganised through a new modal dialogue that is available through the main menu.
A new dockable window available through the main menu allows for adding custom notes to a project. Any RTF content (including text, tables and illustrations) can be included in a note. Multiple note pages can be created if needed.
A new modal dialogue available through the main menu allows for configuring one or more (printable) reports that contain a variety of information items (e.g. general description, image of layout, selection of output sheets, selection of quantity values, selection of input files, ...) pertaining to the project.
The Designer is a new stand-alone GUI Tool that was added to the WEST suite. It allows for performing design-related computations using a number of preconfigured executable models, pertaining to specific layouts (MLE and A2O) and design rules (ATV, Metcalf and Eddy).
The Data Editor is a new stand-alone GUI Tool that was added to the WEST suite. It allows for creating, viewing and modifying data files in WEST format.
Block Details Extensions
The Block Details window has been extended with 2 new visualisation modes. The first enables visualisation of Parameters and Variables in 2 panes (left and right) within the same tabpage, instead of in separate tabpages. Switching between both visualisations is done by clicking "-" and "+" indicators in the top right corner of the Block Details. The second allows for showing "All" Parameters and Variables in the Block Details when multiple blocks are selected, instead of only those that are "Common". Switching between both visualisations is done by clicking "-" and "+" indicators in the top right corner of the Block Details.
Block Summary Extensions
Through extensions to the Block Summary (previously named Info Pane) window, it is now possible to modify values of non-fixed favorite parameters, input variables and derived variables (initial conditions).
The MSL compiler now maps matrices to memory following the row-major rather than the column-major principle. External code that relies on the fact that data items are arranged in column-major fashion will therefore have to be modified.
WEST3 Conversion Tool Mapping Customisation
In the WEST3 Conversion Tool a button labeled "Options" has been added that leads to a conversion mapping table that can be customised (i.e. conversion rules can be added, removed or modified).
Conversion of MATLAB Fuzzy Interface System (FIS) to Executable Code for WEST
CUI tools named tfis2t.exe and tfuzzy.exe have been added to the WEST distribution. These tools allow for converting a MATLAB fuzzy logic model (represented as a *.fis file) to C code that can be called from a MSL model.
COM API added to WESTforAUTOMATION
The WESTforAUTOMATION distribution now contains an API for use with COM applications.
