The first part of the course introduces the continuous adjoint method applied to fluid mechanics with a focus on the key features that make it a valuable tool for industrial problems.

The course is organised with the collaboration of leading experts in the development of continuous adjoint methods in aerodynamics, with a rich portfolio of applications in internal and external aerodynamics, e.g. cars, aircraft, turbomachinery, from the group of Prof. K.C. Giannakoglou, National Technical University of Athens (NTUA).

The training provides examples of process and best practice, useful to existing OpenFOAM users wishing to broaden their application knowledge of OpenFOAM towards adjoint-based optimisation. All features demonstrated in this course will be part of the Official release of OpenFOAM v1912.
