The Aeronautics Pilot comprised of two different use cases.
Avio Aero Turbomachinery Use Case
The first one, Turbomachinery use case, has been focused on accelerating simulations of designed components. The code was rewritten to leverage modern hardware GPU accelerators which led to 21.4x speed up of the computation in comparison to the original computation time. Additionally, a check-pointing mechanism was implemented which saves the state during the computation and restarts the computation at that point in case of system failure. Another feature made available for this use case was simple user-friendly visualisation of the progress through the LEXIS Portal during the computation.

Avio Aero Rotating parts Use Case
The second use case, focused on Rotating Parts, has concentrated on the implementation of a new methodology for the simulation of the advanced hydrodynamics in the complex geometries under turbulent motion. This allows for the definition of the proper accuracy of the simulation and minimisation of the required computing time. Also, the computationally intensive preprocessing phase was included in the LEXIS workflow, making it possible to run the whole computation at once from the LEXIS Portal.
