We’re pleased to announce we're close to releasing the latest version of MassMotion, our class-leading crowd simulation software.

Available for download in the near future, MassMotion version 6 is a significant milestone with a completely revamped user interface for the simulator, which now includes a full featured analysis and reporting system.

New features include: 

• New database back-end for storage of simulation results 
• Powerful filter based querying system 
• New spread sheet based scheduling tools 
• Multiple 3D views 
• Fast 3D playback of results 
• Built in graphing capability 
• Tabular results 
• Density (LOS) textures on geometry 
• Footfall tracking (paths) textures on geometry 
• CSV export 
• Image export 
• Video capture

The latest release of GSA is about to hit the streets. We are nearing the completion of final testing so we thought it would be a good opportunity to share some of the new features within the software. GSA is used throughout the world on major projects, whether that is for steel, concrete or other materials. 

One of the most important considerations for engineers is to link the analysis with reliable design software. This is why we are committed to increasing our capability supporting a wide variety of country design codes as well as everything else.

In 8.7 you will see the following new design codes appear:

Steel Design
EN 1993-1-1:2010 Eurocode 3 (SS)
SANS 10162-1:2011

Concrete Slabs
• ACI 318-11
• ACI 318M-11
• Hong Kong Code of Practice for Structural Use of Concrete 2013
• Indian Railway Standard: Concrete Bridge Code 1997 (2003)
• Canadian Standards Association: A23.3-04 Design of Concrete Structures (2004)

Footfall Analysis
• BS6841: 1987
• BS6472-1: 2008
• User defined frequency weighting curve

In order to allow a wider range of structures to be analysed within GSA we have now introduced Geometrically Non-Linear Shell elements. These elements will accurately model large deflection and rotation problems.

Mesh generation is a complex area but users require a user friendly experience when putting together their models. We have improved our capabilities in this area and introduced a totally new mesh generation tool. The technique for creating the bounding geometry for the meshes will remain largely unchanged, but the end result will provide smaller and better conditioned meshes.

As GSA is used for many esoteric and architecturally driven structures, it has to deal with a wide variety and complexity of shapes. Having the new curved and explicit members will make the experience of analysing these types of structures far easier. Not only are these provided for analysis within GSA but they are also included in the model transfer between Autodesk’s Revit software.

Our link to Autodesk’s Revit software has been improved quite a bit as well and will allow us a higher integrity of model transfer and increased BIM coordination.  

Some highlights for this feature are:

• Revit Marks are exported to GSA as names for members, elements and sections
• Revit slanted columns are exported to GSA members as a column type
• Revit curved members are transferred as GSA curved members
• Additional Section mapping options
• Mapping database may be edited via GSRevit
• GSA offsets are imported into Revit…
...and many more items.

A quick highlight on other new features:

Faster RC Slab Design Capability, Grid Load Expansion Algorithm, better handling of Large Models, Save with Selected Results only, New Element Selection options.
