What is ANSYS CFX and Workbench?
ANSYS CFX is a general purpose Computational Fluid Dynamics (CFD) software tool.

CFX 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.

CFX is able to solve the fluid flow problems that are steady/unsteady, compressible/incompressible, laminar/turbulence/LES, subsonic/transonic/supersonic. CFX can also be used to handle problems with heat transfer (conduction, convection & radiation), multiphase (DPM, Eulerian, VOF), combustion & chemical reaction, dynamic meshing.

Workbench is a software package designed to build and mesh models for computational fluid dynamics (CFD) and other scientific applications. Workbench is used as the default pre-processor for ANSYS CFX CFD solver. CFX-Post is the interface for post-processing.

The official software webpage for CFX is at http://www.ansys.com/Products/cfx.asp.

Access to CFX and Workbench Interface?

CFX and Workbench is supported on all the HPC systems. You can start the software interface using commands from any command line prompt:

>  cfx5  &

 # command to start CFX interface

>  workbench  &

 # command to start Workbench interface


Batch and Parallel Processing of CFX

CFX can only run in serial batch mode in an LSF queue. CFX serial solver is supported at LSF queues linux64, atlas4_large and atlas5_large. You can submit a batch CFX job like:

>  bsub –q linux64 –o myjob.o “cfx5solve -batch -def case1.def -name case1”

where

  • -q  linux64:  submit job to queue linux
  • -o  myjob.o:  save standard output information to file "myjob.o"
  • “cfx5solve -batch -def case1.def -name case1”:   run CFX5 solver in batch mode with the definition file 'case1.def' and save the results and output data to case1.*.
