FLACS-CFD Foundation Certification Exam

Certification for the level FLACS Foundations is awarded by passing the FLACS Foundations Exam. The exam tests both knowledge of how to operate FLACS (functionality) and how to apply FLACS on real problems (best practice). The latter part requires a basic understanding of the phenomena modelled in FLACS and an understanding of the modelling range and limitations. The user should show knowledge about best practices for the main applications of FLACS and should be able to set up a correctly defined scenario including verification and recognize mistakes and deviations from best practice (basic QA).


The exam is based on the FLACS I training and consists of 44 questions that cover five topics:

  • Phenomena/models (10%)
  • Scenario definition (60%)
  • Geometry (10%)
  • Running (10%)
  • Post-processing (10%)



Anyone who would like/ need to use FLACS as a tool in their daily work.



To attain the certification for FLACS Foundations, you must demonstrate that you:

  • understand the basic mechanisms of gas dispersion and explosions and fire;
  • can use FLACS for setting up, running and extracting results for a basic range of typical gas dispersion and gas explosion and fire scenarios;
  • know and understand FLACS user guidelines and best practice for defining the different scenarios;
  • can perform basic QA of scenarios and output to ensure accurate and realistic results;
  • know about common mistakes and issues and how to solve and avoid these; and
  • are able to model and understand the effects of different mitigation measures (pressure relief panels, water deluge, etc.).
