1^st International Workshop VirtualFluids – recordings available

The Institute for Computational Modeling in Civil Engineering (iRMB) organized the 1^st International Workshop on VirtualFluids at the University of Denmark (DTU) in Roskilde from 24-28.03.2025, supported by Erasmus+ teacher and staff mobility and the University of Denmark (DTU) . The workshop was attendant by 23 researchers from four countries and featured theoretical and practical sessions on VirtualFluids.

VirtualFluids is a Computational Fluid Dynamics (CFD) solver based on the lattice Boltzmann method (LBM) for turbulent and multicomponent flow problems. It includes distributed pre- and postprocessing capabilities for simulations with more than 100 billion degrees of freedom.

Recordings of the lectures and some hands-on sessions are available on iRMB’s youtube channel.

• Prof. Martin Geier discussed the theory of the implemented Lattice Boltzmann method.
