[01/01/2009] FSEG RATED ‘WORLD LEADING’ BY PEERS IN RAE 2008

The results of the 2008 Research Assessment Exercise (RAE2008) confirm that the Fire Safety Engineering Group (FSEG) of the University of Greenwich is one of the top research groups in the UK in the area of Mechanical, Aeronautical and Manufacturing Engineering (UoA 28).   FSEG was part of the Centre for Numerical Modelling and Process Analysis (CNMPA) submission to UoA 28.  RAE2008 rated 70% of the submission in the highest two research quality categories, with 30% rated as ‘world leading’ and 40% rated as ‘internationally excellent’.

In the most respected RAE 2008 league table compiled by the Times Higher Education (18th December 2008), the CNMPA submission produced a grade point average of 2.95, placing CNMPA 4th out of the 33 submissions from 32 institutions.  Its 4th place meant that the group was placed higher than 12 of the research intensive Russell Group Universities.   With 30% of its submission rated at the highest quality rating of ‘world leading’, the quality of the CNMPA work was equal to that of Imperial and Sheffield, the top two rated universities.  The average volume of work classified as ‘world leading’ for the area of Mechanical, Aeronautical and Manufacturing Engineering by the assessment panel was only 17%.

CNMPA SCORE PROFILE:
The work of CNMPA was judged as:

Category 4* - World Leading – 30%
Category 3* - Internationally Excellent – 40%
Category 2* - Recognised Internationally – 25%
Category 1* - Recognised Nationally – 5%
Unclassified – Quality that falls short of National Recognised – 0%

[24/02/2011] vrEXODUS VERSION 5.0 IS NOW AVAILABLE!

The release of version 5.0.5 of vrEXODUS involved a complete rewrite of the original vrEXODUS v4.0 taking advantage of dedicated graphics hardware and processing power available with modern PCs. While earlier versions of vrEXODUS incorporated the Superscape software development kit and the Viscape plug in, the new version has been completely rewritten using C++ and making use of DirectX 9.0 libraries. As a result the new software is faster than the older version, making use of both software and hardware features and can handle much larger data sets.

The new vrEXODUS software incorporates all of the features and capabilities of the previous version and has a range of new and improved functionality, including:

New Features and Capabilities
  • Fully integrated screen capture and video output using the wmv file format.
  • Support for multi-core CPUs.
  • vrEXODUS is now dongle locked to the EXODUS dongle.
Improved Features and Capabilities
  • Ability to import, display and animate very large data sets involving very large geometries and hundreds of thousands of agents.
  • Faster loading times for simulations with the ability to drag and drop files into the software.
  • Advanced display controls allowing the visibility of various graphic representations to be toggled on or off.
  • Split screen control, allowing multiple views simultaneously.
  • Improved navigation and playback performance with support for the family of 3D Navigation Devices from 3Dconnexions (http://www.3dconnexion.com/).

[01/06/2008] SMARTFIRE VERSION 4.1 IS NOW AVAILABLE.
SMARTFIRE V4.1is a major new release of the SMARTFIRE software incorporating a numner of new and improved features.

The major new developments include:

  • Update to SMARTFIRE Scenario Designer including support for monochrome Bitmaps as an alternative to the CAD .dxf files, improved search algorithms for rooms and doors, and automated zone creation for "room block" export of data to EXODUS.
  • Update to SMARTFIRE Parallel CFD Engine including improved access to solution controls in the parallel MPI version of SMARTFIRE and an improved parallel CFD launch utility.
  • Update to the SMARTFIRE Case Specification Environment, including support for delayed triggering of events, critical change handling to provide managed time step size control through potentially unstable events, improved control of solution results output, and support for user defined materials. The software also now has a TOXICITY model to control the production and dispersal of the toxic combustion products (e.g. CO, CO2) and other toxic species. The software also has a new HCL release and absorption model.
  • Improved SMARTFIRE Automated Meshing System has user access to fine tune the meshing rules before meshing commences with new support for iterative mesh refinement based on mesh quality metrics for the aspect ratio of cells and the ratio of lengths of adjacent cells.
  • The SMARTFIRE suite of tools has a new research tool for Mesh Morphing. This allows users to manipulate the mesh nodes to create some body fitted mesh morphs. This tool features node selection using logical points range, simple configuration of pitched roofs, sub-region mesh smoothing, and a “Move Object” functionality, which allows a chosen object (e.g. a fire) to be “moved” to a new location – although the exact size and position will depend on the mesh in the target area.
  • Improvements to the SMARTFIRE CFD Engine include new models for Toxicity (CO and CO2) and HCL. A new sprinkler / water mist model allows some of the effects of sprinkler systems to be modelled. Combustion modelling has been improved so that it is much less sensitive to mesh quality. A new 2D slice visualization shows an interactive ray traced visibility distance (through smoke) from a chosen view point. The software also now supports radiation monitor points which allow accurate computation of the thermal radiation flux summation at selected points.
  • Improvements to the SMARTFIRE Data Viewer include the addition of an interactive scalar probe point to report the current value of the scalar field. The software also has a newly developed prototype walk-through/exploration mode to allow movement within a data set/geometry. Support for CSV data export of scalar probes and monitor graphs, has also been added.

There are also a number of minor SMARTFIRE improvements and additions, including:

  • The flow handling algorithm has been improved to give better solution stability.
  • Residual calculation has a normalized version which reduces the detrimental effect of having large numbers of cells.
  • Default settings for solver configuration have been improved to give more balanced (and hence more effective) processing performance.
  • CFD Engine now uses total simulated time (instead of numbers of time steps) to configure the duration of a simulation.
  • Inlets can now support time dependent boundary condition data files.
  • A special form of Inlets can now be placed internally.
  • Improved and clearer interface for wall selection, wall properties and 2D object definition.
    Improved workflow with better tool integration with options for launching most of the other tools of the SMARTFIRE suite, launching data/script file editors and also launching a file browser (Windows Explorer) showing the appropriate working case directory.
  • New objects added to give greater flexibility when creating scenarios: FIXED PRESSURE SURFACE - provides a constant over-pressure, SIMPLE FAN - provides a simple fixed speed fan-like behaviour and a NOZZLE – which supplies droplets of water to the sprinkler model.
  • New logic for monitors and controlled changes so that multiple discrete monitors can combine to give a single triggered event and to allow controlled events to re-occur so that on/off repetitions can occur (currently activated only in script commands).
  • Greater tool integration (e.g. Windows Explorer and SMARTFIRE Data Viewer) under the File menu.
  • New higher order differencing schemes reduce false diffusion.
  • The CFD Engine of SMARTFIRE now supports the output of surface data such as temperatures and radiative fluxes which can be loaded into DataView.
  • Added a clip box to DataView allow visualization within a selected rectangular sub-region.
  • Added a parallel (i.e."cabinet projection") view mode to DataView.
  • Added 3D viewing mode for red/green glasses in DataView.


[25/08/2003] maritimeEXODUS VERSION 4.0 and vrEXODUS VERSION 3.8 ARE NOW AVAILABLE!

With the release of maritimeEXODUS V4.0, maritimeEXODUS maintains its full compliance with the IMO requirements as set out in MSC circular 1033 and in addition, maritimeEXODUS incorporates several new  features. 

NEW FEATURES:

New Behavioural and Geometrical Features:
The release of version 4.0 of maritimeEXODUS incorporates a number of significant fundamental new capabilities.  These concern the representation of:
-    Water Tight Doors,
-    Hatches,
-    60 Degree Stairs and
-    Vertical Ladders. 

These additions not only allow the geometrical representation of these features but also include performance and behavioural additions associated with “trained” crew and “naďve” passengers under conditions of heel and trim. Associated with these new capabilities are data-sets derived from experimental trials commissioned by the UK MoD specifically for the development of these features.  These new capabilities allow maritimeEXODUS to more accurately address scenarios associated with naval vessels and off-shore facilities.   Finally, the vrEXODUS software has also been enhanced to better represent these new capabilities.
