Welcome to BROADCAST documentation!

BROADCAST (multi-Blocks stRuctured high-Order Algorithmically Differentiated Compressible nAvier-stokes Stability Tools) is a software which discretises the compressible Navier-Stokes equations and extracts the linearised state derivative operators through Algorithmic Differentiation providing a toolbox for laminar flow dynamics.

Developer’s repository link is on github.

Check out the Usage section for further information, including the Installation process.

Note
