Large number of the mechanical, aerospace, civil and hydro engineering machines are operating in the complex environment. Floating offshore wind turbine or the helicopter in flight are only a reference examples of the problem. Operational loads and resulting structural response of the investigated object are coming from aerodynamic, hydrodynamic and thermal forces. Traditionally those mechanical systems are being studied w.r.t the different scientific disciplines: solid mechanics, flow mechanics, material sciences and computer methods only to name major domains. It leads to the approximate and often imprecise results of numerical simulations. Muti-physics approach is required to adequately address the complexity of the real-life operation of the mechanical systems. Seasonal School on Computational Fluid-Structure Interaction tries to close the isolated domain analysis gap. The FSI school offers an integrated multidisciplinary training covering the comprehensive spectrum of the mathematical theorems, fluid and solid dynamics, numerical modelling techniques and all this within the framework of the HPC resources and tools able to tackle the challenging problems of the coupled multi-physics problems. Lectures will be followed with the laboratory exercises run on the CI TASK cluster. The course is addressed to wide audience ranging from PhD students to more senior researchers active in the science and industrial R&D departments. Trainings will be hold on virtual laboratory with per-configured virtual machines. Attendees will connect to the laboratory via website client or remote desktop application. All attendees should bring their laptops.
