This course is an introduction into the theory and mechanisms in gas explosion and to the concepts and models within FLACS. It will cover all typical areas of consequence modelling within the software, including ventilation, gas dispersion, gas explosions and mitigation measure (e.g. water deluge, vent panels). This course combines both theory and practical exercises with the FLACS software; therefore students will be required to practice and apply their new knowledge of the software through extensive hands-on workshops. About half the time will consist of presentations and the rest will be hands-on with the FLACS software.
• Introduction: Gexcon, Explosions & FLACS
• Geometry modelling and CAD-import
• Defining scenario (CASD preprocessor)
• Setting the grid, calculating porosities
• Visualizing results (FlowVis postprocessor)
• Ventilation and Dispersion with FLACS
• Pool spread
• Validation testing and procedures for CFD
• Mitigation of explosions
• Explosion Risk Analysis
• Efficient Use of FLACS and QA
Who should attend?
People who intend to carry out consequence modelling with FLACS or work closely together people performing these types of FLACS simulations. These include safety engineers and consultants in risk consultancy companies, oil & gas and process industries, regulatory bodies, engineering companies, nuclear industry and many more. The course could potentially also be useful for structural and process engineers, as these disciplines can benefit of using results from FLACS studies, by providing a better understanding of the most relevant parameters and mechanisms.
Attendance of this course is mandatory for FLACS users

FLACS-II (Advanced) Courses
There are a range of FLACS code capabilities not fully covered in the introductory FLACS I course program. An additional 2-days course is proposed for advanced applications and modeling. The course format is a library of modules that match advanced exercises and relevant presentations; the duration of a module is approximately 2.5h. The 2-days course agenda is typically composed by 6 modules; the course program can be adjusted according to Clients' requests.
Modules (presentation + exercise) currently proposed are:
• Anticipated Congestion modeling (AC)
• Blast load and structural response
• Gas detection systems optimization
• HVAC systems modeling
Additional modules and topics (a couple can be added according to clients’ requests):
• V10 and more: Update on more recent features (for old FLACS users)
• Vessel burst, impulsive (TNT type) blast loading
• Miscellanea of advanced features (using setup/cc file)
• Advanced post-processing (using r3file/a3file)
• Flash and Pool: How to define release models
• Full ventilation/dispersion/equivalent gas cloud/explosion exercise
• Advanced exercises using a real case geometry (if available/proposed by a client)
• Wind modeling
Who should attend?
This course is intended for FLACS users who want to increase their skill on FLACS use, and have an insight on the selected list of topics. These include safety engineers and consultants in risk consultancy companies, oil & gas and process industries, regulatory bodies, engineering companies, nuclear industry and many more. Depending on the selected list of modules, the course could potentially also be useful for structural and process engineers.
