Gexcon is pleased to introduce a series of important updates across the FLACS ecosystem, bringing improved usability and enhanced workflow efficiency for engineers and safety specialists. These enhancements span across Multiscenario, the Python API, FLACS Cloud, Autogrid, FGC, and Flowvis, ensuring a smoother, faster, and more intuitive user experience.
The RISK module has now been fully deprecated and removed from the FLACS package. Large simulation sets can now be created easily and efficiently in Multiscenario, addressing the needs of FLACS-Risk users. This change streamlines the software suite and ensures that users are working with the most current and supported modelling tools.
The latest version can be accessed here.

Key improvements
Significant quality‑of‑life enhancements and improved Autogrid integration in Multiscenario
Modernisation of module installation and IDE support
More flexible cloud simulation management
New capabilities and UX improvements in Autogrid
Improvements to turbulence, solids handling, and visualisation performance
Improved FGC calculation options
Reduced CGNS loading times
Multiscenario Enhancements
A series of improvements have been introduced to make scenario management smoother and more efficient:
The 3D view now updates automatically whenever the grid or geometry is modified, improving visualisation and understanding of the current scenario.
Leak handling has been made more robust and reliable.
Error handling for nodes has been upgraded, helping users diagnose and resolve setup issues more quickly.
New autogrid configuration properties offer greater flexibility when creating grids.
Autogrid setups are now automatically reused when exporting multiple scenarios, speeding up batch exports.
Users can now generate unique job numbers when exporting simulations to multiple folders.
A new search filter has been added to the table view, making it easier to locate specific scenarios in large projects.
Support has been added for user‑defined species, expanding the modelling flexibility within multiscenario projects.
Python API
The Python experience has been significantly modernised:
FLACS modules can now be installed directly using
pip install, making setup faster and more accessible.The modules are now fully recognised in IDEs, greatly enhancing the workflow for users who automate or batch‑process simulations.
FLACS Cloud
FLACS Cloud has been enhanced to better support users working across large sets of cloud simulations:
Users can now delete multiple simulations at once, simplifying project cleanup.
The usage report has been expanded to include CPU usage details, enabling better tracking of resource consumption.
Simulations can now be run using external nodes.
Autogrid
Autogrid continues to evolve with new modelling capabilities and usability improvements:
Blast grid guidelines have been added as an experimental feature to support condensed phase explosions.
New support for multi‑directional leaks.
Various user‑experience enhancements help streamline the grid setup process.
FGC
Several improvements have been introduced to help improve porosity calculations:
Turbulence calculations are now skipped by default when not required, reducing porosity file calculation times.
A new flood‑fill method for filling solids has been added, improving blockage representation in situations where a solid is made up of several non‑solid sub‑objects.
Flowvis
Flowvis receives notable performance boosts:
3D plot performance has been improved.
Loading times for CGNS files have been significantly reduced, enabling quicker visualisation of large simulation files.
