This page provides information about the environment settings that the user
must include in their .cshrc file in order to use Fluent, Fidap and Gambit.
In addition, it is recommended that the user
sends an email to flow@ncsa.uiuc.edu
indicating their intent to use this software. The login of the user will then
be included in the software access list. This information
is essential for deciding the number of licenses that NCSA must purchase
every year, for the use of these commercial packages.
If you have any questions about the information on this page, please email

Fluent is a general purpose package for modeling fluid flow and heat
transfer. It can simulate two-/three-dimensional, steady/unsteady,
compressible/incompressible flows in structured and unstructured grids. The
Mach number of Fluent simulation ranges from subsonic to hypersonic. Its
capabilities include simulating non-isothermal flows, disperse phase/droplets,
combustion and radiation heat transfer, and flow-through porous media.
The current version of Fluent 6 is version 6.3.26.
To use Fluent6 on the IBM p690 supercomputer, add the following lines
to the end of the .cshrc file in your home directory:
# Fluent settings
setenv FLUENT_HOME /usr/apps/cfd/Fluent-6.3.26/Fluent.Inc
set path = ($FLUENT_HOME/bin $path)
To use Fluent6 on NCSA's Tungsten cluster, add the following lines
to the end of the .cshrc file in your home directory:
# Fluent settings
setenv FLUENT_HOME /usr/apps/cfd/Fluent-6.3.26/Fluent.Inc
set path = ($FLUENT_HOME/bin $path)
setenv FLUENT_ARCH lnx86
To start Fluent6 from the command line, you can specify the dimensionality
of the problem (2D or 3D), as well as the precision of calculation (single
or double).
- fluent 2d runs the two-dimensional, single-precision solver
- fluent 3d runs the three-dimensional, single-precision solver
- fluent 2ddp runs the two-dimensional, double-precision solver
- fluent 3ddp runs the three-dimensional, double-precision solver

Gambit is an integrated preprocessor for CFD analysis. It can be used
to build geometry and to generate a mesh, or to import a geometry created by
a third-party CAD/CAE package. The environment required by Gambit is
the same as the one required by Fluent. Therefore, refer to the Fluent
section on how to add the path in the .cshrc file.
Once the environment is set up, enter the following command:
gambit [option1 option2]
to start Gambit.
The command
gambit -help
displays the available start-up options.
The Gambit User's Guide is located in the
/usr/apps/cfd/Fluent-6.3.26/Fluent.Inc/gambit2.3.16/help
directory on the IA-32 Linux cluster (Tungsten) and the IBM p690 platform
(Copper). In addition to html documents, PDF formatted documents are available
as well.

FIDAP is a fluid dynamics analysis package that uses the finite element
method to simulate many classes of incompressible and compressible fluid flows.
Possible simulations include two-dimensional, axisymmetric and three-dimensional
steady state or transient simulations in complex geometries including the
effects of temperature and the presence of chemical species. Multi-phase and
turbulent flows can also be simulated. FIDAP has been officially merged with
Fluent. The current version of FIDAP is
8.7.4 on the IA-32 (Tungsten)
cluster and the IBM p690 (Copper)
platform. The environment required by Gambit is
the same as the one required by Fluent. Therefore, refer to the Fluent
section on how to add the path in the .cshrc file.
The Fidap User's Guide is located in the
/usr/apps/cfd/Fluent-6.3.26/Fluent.Inc/fidap8.7.4/help
directory on the IA-32 Linux cluster (Tungsten) and the IBM p690 platform
(Copper). In addition to html formats, PDF formatted documents are available
as well.
