About the presentation

Title: Beyond boxes and cylinders – the challenges and opportunities for using mesh geometries in FLACS-CFD

Traditionally FLACS-CFD has used box and cylinder volumetric primitive objects exclusively to represent complex geometry. This engineering approach has many advantages and has worked well for various types of installation. However, with ever more complex CAD models, shorter project timelines, and new application areas, this approach is becoming more and more limiting. This is one of the reasons why we are developing new routines and algorithms to use mesh geometric objects directly in FLACS-CFD simulations

Djurre presents the work that has been done so far on supporting mesh object geometries in future versions of FLACS-CFD, including some initial validation.

Senior Manager @ Gexcon

Djurre holds a BSc and MSc in Aerospace Engineering from the Technical University Delft and a BSc in Cognitive Psychology from the University of Leiden. He has been working in the oil and has energy sector for more than 15 years in various roles, including structural engineering, technical safety consultancy, and FLACS-CFD product management. During the last two years, he has been managing the Gexcon research and software development department.

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.
