The main goal of ExaFLOW  is to address key algorithmic challenges in CFD (Computational Fluid Dynamics) to enable simulation at exascale, guided by a number of use cases of industrial relevance, and to provide open-source pilot implementations. Thus, driven by problems of practical engineering interest, we focus on important simulation aspects, including:

  • error control and adaptive mesh refinement in complex computational domains,
  • resilience and fault tolerance in complex simulations,
  • solver efficiency via mixed discontinuous and continuous Galerkin methods and appropriate optimised preconditioners,
  • heterogeneous modelling to allow for different solution algorithms in different domain zones,
  • evaluation of energy efficiency in solver design, and
  • parallel input/output and in-situ compression for extreme data.
