While offering high theoretical peak performance and high memory bandwidth, to efficiently exploit these systems, complex programming mode ls and significant programming investments are necessary. Furthermore, mos t known pre and exascale systems currently planned or installed, e.g. Fron tier, Leonardo and LUMI, contain a large fraction of accelerators. Thus, t he challenge of porting and tuning scientific codes for these new platform s can no longer be ignored. However, established CFD codes build on years of verification and validation of their underlying numerical methods, pote ntially preventing a complete rewrite and rendering disruptive code change s a delicate task. Therefore, porting established codes to accelerators po ses several interdisciplinary challenges, from formulating suitable numeri cal methods to applying sound software engineering practices to cope with disruptive code changes. The wide range of topics makes the exascale CFD t ransition relevant to a broader audience, extending outside the traditiona l fluid dynamics community. This minisymposium aims at bringing together t he CFD community as a whole, from domain scientists to HPC experts, to dis cuss current and future challenges towards enabling exascale fluid dynamic s simulations on anticipated accelerated systems.\n\nSustainable and Relia ble Computing with Tools: Analyzing Precision Appetites of CFD Application s with VerifiCarlo\n\nThe energy consumption constraint for large-scale co mputing encourages scientists to revise the architecture design of hardwar e but also applications, algorithms, as well as the underlying working/ st orage precision.

Thus, it is necessary to develop accurate yet cost-effective models for o uter-loop problems involving turbulent flows.
