A brief description of what is in each chapter follows:

• Chapter  1, describes options and alternatives to starting, running, and exiting ANSYS FLUENT. It also provides instructions for remote execution, batch execution, and using the Remote Simulation Facility (RSF).

• Chapter  2, describes the mechanics of using the graphical user interface and the GUI on-line help.

• Chapter  3, describes the mechanics of using the text interface and the TUI on-line help. (See the separate Text Command List for information about specific text interface commands.)

• Chapter  4, describes the files that ANSYS FLUENT can read and write, including picture files.

• Chapter  5, describes how to use the standard and custom unit systems available in ANSYS FLUENT.

• Chapter  6, describes the various sources of computational meshes and explains how to obtain diagnostic information about the mesh and how to modify it by scaling, translating, and other methods. This chapter also contains information about the use of non-conformal meshes.

• Chapter  7, describes the different types of boundary conditions available in ANSYS FLUENT, when to use them, how to define them, and how to define boundary profiles and volumetric sources and fix the value of a variable in a particular region. It also contains information about porous media and lumped parameter models.

• Chapter  8, describes the physical properties of materials and the equations that ANSYS FLUENT uses to compute the properties from the information that you input.

• Chapter  9, describes the governing equations and physical models used by ANSYS FLUENT to compute fluid flow (including periodic flow, swirling and rotating flows, compressible flows, and inviscid flows), as well as the inputs you need to provide to use these models.

• Chapter  10, describes the use of single rotating reference frames, multiple moving reference frames, and mixing planes in ANSYS FLUENT.

• Chapter  11, describes the use of sliding and deforming meshes in ANSYS FLUENT.

• Chapter  12, describes ANSYS FLUENT's models for turbulent flow and when and how to use them.

• Chapter  13, describes the physical models used by ANSYS FLUENT to compute heat transfer (including convective and conductive heat transfer, natural convection, radiative heat transfer, and periodic heat transfer), as well as the inputs you need to provide to use these models.

• Chapter  14, describes ANSYS FLUENT's heat exchanger models and how to use them.

• Chapter  15, describes the finite-rate chemistry models in ANSYS FLUENT and how to use them. This chapter also provides information about modeling species transport in non-reacting flows.

• Chapter  16, describes the non-premixed combustion model and how to use it. This chapter includes details about using prePDF.

• Chapter  17, describes the premixed combustion model and how to use it.

• Chapter  18, describes the partially premixed combustion model and how to use it.

• Chapter  19, describes the composition PDF transport model and how to use it.

• Chapter  20, describes the engine ignition models available in ANSYS FLUENT.

• Chapter  21, describes the models for the formation of NOx, SOx, and soot and how to use them.

• Chapter  22, describes the acoustics model and how to use it.

• Chapter  23, describes the discrete phase models available in ANSYS FLUENT and how to use them.

• Chapter  24, describes the general multiphase models available in ANSYS FLUENT (VOF, mixture, and Eulerian) and how to use them.

• Chapter  25, describes ANSYS FLUENT's model for solidification and melting and how to use it.

• Chapter  26, describes the ANSYS FLUENT solvers and how to use them.

• Chapter  27, describes the solution-adaptive mesh refinement feature in ANSYS FLUENT and how to use it.

• Chapter  28, describes how to create surfaces in the domain on which you can examine ANSYS FLUENT solution data.

• Chapter  29, describes the graphics tools that you can use to examine your ANSYS FLUENT solution.

• Chapter  30, describes how to obtain reports of fluxes, forces, surface integrals, and other solution data.

• Chapter  31, describes the flow variables that appear in the variable selection drop-down lists in ANSYS FLUENT dialog boxes, and tells you how to create your own custom field functions.

• Chapter  32, describes the parallel processing features in ANSYS FLUENT and how to use them. This chapter also provides information about partitioning your mesh for parallel processing.

• Appendix  A, presents a chart outlining the compatibility of several FLUENT model categories.

• Appendix  B, presents information about the contents and formats of ANSYS FLUENT case and data files.
