This paper introduces Jatayu – the in-house parallel, three-dimensional, all-speed, finite-volume, unstructured-grid-framework-based Computational Fluid Dynamics (CFD) solver aimed specifically at high speed flow applications. Jatayu is written in C++ as an object oriented programming platform(O2P2), which creates each physics model as a separate library, that can be dynamically loaded during run-time. This makes Jatayu very modular and flexible, such that it can be easily extended to solve any arbitrary set of equations for multi-physics problems relevant to aerospace such as combustion, aero-acoustics, etc., without affecting other modules in the solver. Jatayu is also capable of harnessing the high-performance scientific computing by using MPI and the ATLAS library for solving complex aerospace applications. We present an overview of current capabilities of Jatayu along with their brief description in terms of physical models and numerical methods. The paper also presents two challenging benchmark problems solved using Jatayu, the first over a missile body at Ma = 7, the second over a DLR R − 6 aircraft at transonic speeds. © 2022, American Institute of Aeronautics and Astronautics Inc, AIAA.
