Olav has a physics degree from NTNU and has worked with explosion modelling and FLACS since 1993. In the 1990s, he was a FLACS-CFD developer with a particular focus on validation against experiments and made a FLACS-CFD training course. In the 2000s, he was Gexcon R&D Director in charge of the FLACS-CFD development team and global sales until he started Gexcon US in 2008-2010. From 2012, Olav has worked as consultant for GL (2012-2013) and LR (2014-2020).

After starting HYEX Safety in June 2020, he has been working full-time with consulting work within hydrogen safety. Model validation and accuracy in CFD predictions have been the key focus of his work, and he is author of numerous articles related to FLACS-CFD.

Lorenzo has a background in Environmental Engineering and more than 15 years of experience with the development and application of simulation engines in the fields of gas dispersion and consequence analysis. His main research interests include atmospheric flows, multiphase flows, and gas explosions. Lorenzo ​​has extensive experience in software development and scientific programming. He has made substantial contributions to the recent development of FLACS-CFD and associated utilities, including the Ewan and Moodie release model, entraining leaks functionality, modelling of aerodynamic roughness, and others. He has developed FLACS-CFD’s Multiphase Drift Flux solver to simulate droplet vaporization and deposition.

In the last 3 years, Lorenzo has authored four publications in peer-reviewed journals. He is part of the scientific committee of the International Conference on Hydrogen Safety – 2021. Lorenzo has been working in Gexcon for 8 years, developing and using FLACS-CFD for consequence analysis and dispersion modelling.

About FLUG Meeting

FLACS-CFD User Group (FLUG) provides an opportunity for Gexcon and users of FLACS-CFD to share updates, insights, and experiences.

It consists of engaging case study presentations and the latest information on FLACS-CFD software research and development.

FLUG 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.
