An Object-Oriented Toolkit for Solving Partial Differential Equations in Complex Geometry

Cylindrical shock impacting and diffracting past 16 cylinders (Cgcns).

Cgcns: Compressible Flow Solver

1. compressible Navier-Stokes and inviscid Euler equations.
2. support for adaptive mesh refinement and moving rigid-bodies.
3. high-speed reactive flow and detonations.
4. Reactions: one-step, ignition and growth model.
5. Equations of state: ideal gas, stiffened gas, JWL, Mie-Grunesien, user defined.
6. multi-fluid formulation (e.g. for two gases with different gas constants).
7. compressible multi-phase formulation.
