NGA2

NGA2 is a high performance computing research library that provides a variety of finite volumes/finite difference solvers for typical fluid-related partial differential equations including:

• incompressible Navier-Stokes
• low-Mach number variable-density Navier-Stokes
• two-phase incompressible Navier-Stokes
• two-phase compressible Navier-Stokes
• constant and variable density scalar transport
• phasic volume fraction for volume-of-fluid methods
• overset and multi-block meshes via parallel coupler
• Lagrangian particle tracking
• large-eddy simulation models
• immersed boundaries
• peridynamics solver
• fft-accelerated linear solvers

Currently, NGA2 supports cartesian meshes only. However, because it is object-oriented, multiple meshes can be used simultaneously and interactively.

Future developments will focus on providing support for:

• cylindrical meshes
• dynamic remeshing
• basic unstructured meshes
• chemical kinetics and combustion models

NGA2 is open-sourced under the MIT license.
