Description

This paper accompanies the publication of the open source lattice Boltzmann solver VirtualFluids [DOI: 10.5281/zenodo.10283048]. Key features of VirtualFluids are the cumulant collision operator, the ability to run multi-scale simulations based on compact interpolation grid refinement and its implementations for both GPU and massively parallel CPU systems. The differences in data structure for the different systems are explained in detail.
