About the presentation
Title: FLACS-CFD validation and sensitivities
Shona discusses the importance and challenges of validating FLACS-CFD to ensure its accuracy and reliability for simulating the consequences of loss of containment scenarios. She demonstrates how Gexcon’s R&D team validates FLACS-CFD. She also presents some plots that were used to determine appropriate recommendations for cases where the initial turbulence conditions are unknown and must be assumed.
In addition, the presentation discusses the work to assess FLACS-CFD sensitivity to grid resolution and how this sensitivity affects simulation accuracy, which led to the recommended grid resolution for gas explosions being revised.

Shona Mackie
Senior Research Engineer @ Gexcon
Shona holds a PhD in Geosciences, awarded by the University of Edinburgh. She has 12 years of experience in research in various fields in academia and industry, which have included developing and analysing large models to predict renewable energy production, model radiative transfer for Earth observation, predict and monitor volcanic ash hazards, and project future climate.
About FLUG
The FLACS User Group (FLUG) is a high-profile discussion forum for engineers, safety experts, and industry scholars.
FLUG meets to discuss new software developments and safety-related topics. Its work has played an integral role in the development of Gexcon’s industry-leading software, which represents more than 40 years of extensive and unrivalled modelling and validation work.
