DescriptionUncertainty in the input data is a reality of engineering practice, albeit not always modelled in simulations. Accurate quantification of the resulting output uncertainty yields finer control on the robustness and cost of designs. However, this quantification requires exploring the parameter space – usually with numerous simulations – which may incur a prohibitive cost, especially for involved studies such as optimal design in fluid dynamics. Parallel computing can make such studies tractable, provided suitable methods are used to leverage it. This is an active field of research especially relevant for fluid dynamics, whose simulations are notoriously expensive and intricate, while being critical to many applications: aeronautics, civil engineering, meteorology, etc. Presented here are novel research developments from ExaQUte, an EU-H2020 project developing HPC methods for robust engineering design. The driving application is the optimisation of building shapes for civil engineering under uncertain wind loads. Therefore, this mini-symposium encompasses unsteady fluid problems, adaptive meshing, uncertainty quantification, robust shape optimisation and more. The methods discussed here are designed to leverage parallelisation with a modern framework for current and future distributed computing environments.
