What is FLUENT and GAMBIT?
FLUENT is a general purpose Computational Fluid Dynamics (CFD) software tool.
FLUENT is an engineering design and analysis tool for fluid flow, heat transfer, chemical reactions and combustion problems, etc. The software is capable of predicting the external/internal aerodynamics performance of an aircraft or automobile, ship hull resistance, hydrodynamic performance of water-jet propulsion system, fire and smoke movement in a building enclosure, mixing and combustion processes, thermal management of electronics system, components or packages, and among others.
FLUENT is able to solve the fluid flow problems that are steady/unsteady, compressible/incompressible, laminar/turbulence/LES, subsonic/transonic/supersonic. FLUENT can also be used to handle problems with heat transfer (conduction, convection & radiation), multiphase (DPM, Eulerian, VOF), combustion & chemical reaction, dynamic meshing. Solution adaption is a specific and useful tool of FLUENT. Users can also write their own User Define Functions (UDF) to couple with FLUENT solver for their particular analyses.
GAMBIT is a software package designed to build and mesh models for computational fluid dynamics (CFD) and other scientific applications. GAMBIT receives user input by means of its graphical user interface (GUI). The GAMBIT GUI makes the basic steps of building, meshing, and assigning zone types to a model simple and intuitive, yet it is versatile enough to accommodate a wide range of modeling applications.
GAMBIT is used as the default pre-processor for FLUENT CFD solver. FLUENT is the interface for both solver and post-processing. Currently there have two major Fluent versions are available: 6.3 and 12.1. With the upgrading of Fluent to version 12.1, ANSYS Workbench is recommended by the software developer as the pre-processor for Fluent solver. Model created in Gambit can still be read into Fluent 12.1.
The official software webpage for FLUENT is at http://www.fluent.com.
Access to FLUENT, GAMBIT and Workbench Interface?
FLUENT and GAMBIT is supported on all the HPC systems. You can start the software interface using commands from any command line prompt:
| > fluent & | # command to start Fluent 6.3 interface |
| > fluent12 & | # command to start Fluent 12.1 interface |
| > gambit & | # command to start Gambit interface |
| > workbench & | # command to start Workbench interface |
Batch and Parallel Processing of FLUENT
FLUENT solver can be run in batch mode in an LSF queue when compute a job taking long hours. FLUENT was very well parallelized and can perform very well in speeding up the simulation when runs on multiple processors.
The details of how to run FLUENT solver in batch/parallel can be found at Parallel Computing.
