CAA++ provides a suite of tools for the simulation of flow-driven acoustics which requires detailed resolution of the small, noise-generating turbulent eddies and the full spectrum of transmitted acoustic waves.

CFD++ can be used to simulate compressible and incompressible fluids and flows, unsteady and steady flows, large range of speed regimes including low speeds through subsonic, transonic, supersonic and hypersonic speeds, laminar and turbulent flows, various equations of state.

CFDShip-Iowa solves the incompressible Reynolds-averaged Navier-Stokes and continuity equations with a variety of turbulence models, and a single-phase level set method to accommodate free surface problems. Since it has been specifically developed for surface-ship and marine-propulsor flow problems, it has an array of ship hydrodynamic specific subroutines and post-processors.

The FrontFlow/blue (FFB) is a finite element method solver for incompressible turbulent flows by LES and RANS with second-order accuracy in terms both of time and space. Standard Smagorinsky model (SSM) and dynamic Smagorinsky model (DSM) are implemented for the SGS model, and SA model is implemented for RANS.

Crank-Nicolson method and fractional step (FS) method are implemented to solve the momentum equations and the pressure Poisson equation, respectively. FFB runs in massively parallel by the domain decomposition method.

Flow-3D is a multi-physics computational fluid dynamics package and provides an insight into many physical flow processes, including solutions coupled to thermal energy transfer, 6-degree of freedom fluid-solid interaction, and mechanical and thermal stress analysis. Flow-3D is an all-inclusive package from setup to simulation to post-processing. No additional modules are necessary.

Previously known as OpenFOAM-dev and OpenFOAM-extend, the foam-extend project is a fork of the OpenFOAM open source library for Computational Fluid Dynamics (CFD).

It contains bug fixes and performance improvements, as well as extensions and additional features provided by community contributors such as dynamic mesh and topological change support, turbomachinery extensions including general grid interpolation (GGI), cyclic GGI and mixing plane, block-coupled matrix support, implicitly coupled conjugate heat transfer and other physics coupling, finite area method, comprehensive dynamic mesh (motion and topological changes) capability and GPU support.

Gerris is a software program for the solution of the partial differential equations describing fluid flow. It is a tree-based adaptive solver for the incompressible Euler equations in complex geometries.

Gerris was developed from scratch by Stéphane Popinet starting in 2001. The first version was released as GPL-licensed code in September 2001. Gerris is not an adaptation of any previous existing code.

HiFiLES (High Fidelity Large Eddy Simulation) is a high-order LES solver developed in the Aerospace Computing Laboratory (ACL) at Stanford University. It is written in C++. The code uses the MPI protocol to run on multiple processors and CUDA to harness GPU performance.

High-order numerical schemes have the potential to advance CFD beyond the current plateau of second-order methods and RANS turbulence modeling, ushering in new levels of accuracy and computational efficiency in turbulent flow simulations.

NavyFOAM is an OpenFOAM derivative specially tailored and customized for broad range of hydrodynamic studies by  NSWCCD for use on US Government projects and the code is not being redistributed. It possibly contains some new schemes and models mainly for VOF. The hydrodynamic interests are powering, propulsion, propulsor inflow, maneuvering and seakeeping computations.

NFA (Numerical Flow Analysis) is a fortran code and solves the Navier-Stokes equations utilizing a Cartesian grid cut-cell formulation with a second-order accurate, volume-of-fluid (VOF) interface-capturing technique to model the unsteady flow of air and water around moving bodies.

Turbulence is modeled with an implicit subgrid-scale model that is built into the treatment of the convective terms in the momentum equations. A domain decomposition method is used to distribute portions of the solution domain over a large number of processors.

The OpenFOAM (Open Field Operation and Manipulation) CFD Toolbox is a free, open source CFD software package which has a large user base across most areas of engineering and science, from both commercial and academic organisations.

OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.

Reef3D is a CFD program with special focus on solving problems in the field of marine, coastal and ocean engineering. The code is fully parallelized using the MPI library and tested up to 1024 processors.

Tdyn CFD+HT is a computational fluid dynamics solver. The solver uses FEM approach and has been applied to the simulation of aerodynamics, hydrodynamics and heat transfer phenomena. The software allows choosing between 14 turbulence models including RANS, ILES and DES.
