COMMERCIAL & OPEN SOURCE
CFD Workshop: Commercial CFD software
NON COMMERCIAL PACKAGES: OPEN SOURCE
Analysis needs different approach
either for a single project, or for all of their
CFD simulations.
For example, your projects might
require the inclusion of terms in the governing
equations which are normally neglected
(because they're very small in most cases).
Or, you might require a higher order
scheme than is commonly available (for an
acoustics application, perhaps).
Or maybe your budget just won't
stretch for the licensing costs.
If you need something besides the
commercial packages, there are many high
quality CFD solvers which are freely available
from one source or another
COMMERCIAL PACKAGES
Usually have the whole package, pre-
processing, cad-integration and Post-
processing
Generalized analysis packages

SU2
The Stanford University Unstructured (SU2) suite is an open-source
collection of software tools written in C++
Performing Partial Dierential Equation (PDE) analysis and solving PDE-
constrained optimization problems.
Toolset is designed with computational fluid dynamics and
aerodynamic shape optimization
Ideal for performing multi-physics simulations, including multi-species
thermochemical non- equilibrium flow analysis, combustion modeling,
two-phase ow simulations, magnetohydrodynamics simulations, etc.
However, it seems that SU2 is in its infancy and has a long way to be
mature and bug-free.
OVERFLOW
The OVERset grid FLOW solver is a software package for simulating fluid
flow around solid bodies using computational fluid dynamics.
It is a compressible 3-D flow solver that solves the time-dependent,
Reynolds-averaged, Navier-Stokes equations using multiple overset
structured grids.
Scientists use OVERFLOW to better understand the aerodynamic
forces on a vehicle by evaluating the flow field surrounding the vehicle..
OVERFLOW has also been used to simulate the effect of debris on the
space shuttle launch vehicle
Open FOAMThis code is a library of C++ routines that facilitates the numerical
solution of partial dierential equations.
Many different solvers (included with the software) have been built to
address many classes of problems.
Applications range from laminar incompressible flow to fully turbulent
reacting compressible flow.
OpenFOAM is freely available under the GNU Public License.
It solves partial differential equations on an unstructured meshes and
for post-processing, the distribution comes with a version of ParaView.
GERRIS
This CFD solver is developed by Stéphane Popinet, with support from the New
Zealand National Institute of Water and Atmospheric Research.
Gerris solves the incompressible Euler, Stokes, or Navier-Stokes equations
using unstructured Cartesian meshes with immersed boundaries.
This allows the use of dynamic mesh refinement to automatically generate
quality grids around complex geometries
Best suited for unsteady flows.
But no turbulence models are available.
Gerris is freely available under the GNU Public License.

COMMERCIAL SOFTWARES
ABAQUS-simuliaAbaqus/CFD provides advanced computational fluid dynamics capabilities with
extensive support for preprocessing and postprocessing provided in Abaqus/CAE.
Address a broad range of nonlinear coupled fluid-thermal and fluid-structural
problems.
Abaqus/CFD can solve the following types of incompressible flow problems:
Laminar and turbulent: Internal or external flows that are steady-state or transient,.
Thermal convective: Problems that involve heat transfer and require an energy
equation and that may involve buoyancy-driven flows (i.e., natural convection) can
also be solved with Abaqus/CFD.
Turbulent heat transfer for a broad range of Prandtl numbers.
Deforming-mesh ALE: Deforming-mesh problems may include prescribed boundary
motion that induces fluid flow or the problems with the boundary motion is relatively
independent of the fluid flow.
