BLASTER
BLASTER (Boundary Layer Adjoint Solver for Transonic External and high Reynolds number flow) is an open-source boundary layer solver and a Viscous-Inviscid Interaction (VII) interface written in C++ and Python. BLASTER is able to compute transonic high Reynolds number flows and laminar and turbulent subsonic compressible flows, including attached and mildly separated flows. It can accurately predict transitions using empirical correlations. The interface can handle two and three-dimensional geometries using a strip based methodology.
Blaster is developed at the University of Liège by Paul Dechamps with the active collaboration of Adrien Crovato and Amaury Bilocq and the help of Romain Boman, and under the supervision of Grigorios Dimitriadis and Vincent E. Terrapon, since 2021.


Interfaces
Blaster is currently interfaced with different inviscid flow solvers in order to perform viscous-inviscid interaction
