250902470.docINTRODUCTION TO ANSYS

The ANSYS program is a computer program for nite elementanalysis and design. You use the program to nd out how a given design worksunder operating conditions. You can also use the ANSYS program to calculatethe p roper d esign for gi ven operating conditions.

The ANSYS program is a general-purpose program, meaning that youcan use i t for a lmost any type of nite el ement analysis in virtually a ny industry-automobiles, aerospace, railways, machinery, electronics, sporting goods, powergeneration, power transmission, and biomechanics, to mention just a few.General-purpose also refers to the fact that the program can be used in alldisciplines of en gineering-structural, mechanical, electrical, electromagnetic,electronic, thermal, uid, and biomedical.

A TYPICAL ANALYSIS

The ANSIS program has many nite element analysis capabilitiesranging from a simple, linear st atic analysis to a complex, nonlinear transientdynamic a nalysis.

STRUCTURAL ANALYSIS

Many types of structural analysis are available in the ANSYSprogram. The primary unknowns (nodal degree of freedom) calculated in astructural analysis are displacements. Other quantities, su ch as strains,stresses, and reaction forces, are t hen derived from the n odal displacements.

The following types of stStatic AnalysisModal AnalysisHarmonic an alysis Transient dynamic an alysis

Spectrum analysisBuckling analysis

In addition to the above analysis types, several special-purpose features areavailable, such as fracture m echanics, composites a nd fatigue.

THERMAL ANALYSIS

Thermal analyses are used to calculate the temperaturedistribution and related thermal quantities in an object. The ANSYS programuses a heat ba lance equation obtained from the principle of conservation ofenergy as the basis for thermal analysis. All three primary modes of heattransfer-conduction, convection, and radiation are handled by the ANSYSprogram. In addition to the three m odes of heat t ransfer, you can account forspecial effects su ch as ch ange of phase a nd internal heat generation.

. Transient thermal analysis

MAGNETIC FIELD ANALYSIS



6/33

Magnetic analyses are used to calculate the magnetic eld in devicessuch as power generators, transformers, video display devices a nd so forth. The

ANSYS program uses Maxwell's equations as the basis for magnetic eldanalysis. The three types of magnetic an alyses a re possible:

Static m agnetic a nalysisHarmonic magnetic an alysis

Transient magnetic analysis

Six element types are available for magnetic analysis, consisting of 2-Delement, three 3-D elements, and one 3-D current-source line element.

ELECTRIC FIELD ANALYSIS

Electric eld analysis is used to calculate the electric eld in

conductive or capacitive systems. The ANSYS program uses Lap lace equ ation asthe b asis for st atic e lectric eld analysis.

FLUID ANALYSIS

A "uid analysis" in the ANSIS program may mean any of thefollowing ca pabilities:

Fluid ow with heat transfer Acoustics

Contained uidDynamic uid coupling

COUPLED-FIELD ANALYSIS

A coupled-eld analysis is one that takes into account theinteraction (coupling) between two or m ore d isciplines o f engineering.

MODEL GENERATION

The ultimate purpose of your nite-element analysis is to recreatemathematically the behavior of an actual engineering system. The modelgeneration will mean the process of dening the geometric conguration of yourmode's nodes and elements.

LOADING AND SOLUTION

The primary objective of a nite element analysis is to examine theresponses o f a structure or com ponent to certain loading conditions. Specifyingthe proper loading conditions is, therefore, a key step in the analysis. You canapply loads on the model in a variety of ways in the ANSYS program. Also withthe help of load step options, you can control how the loads a re actually usedduring solution.

LOADING

A load step is simply a conguration of loads for which a solution isobtained. How to apply loads? Most loads can be applied either on the solidmodel or on the nite element model.

SOLUTION

Two methods of solution are available in the ANSYS program:frontal solution and Jacobin conjugate gradient (JCG)solution. You can choosethe m ethod as an analysis op tion. By default, the frontal method is u sed.

POST PROCESSING

Post processing is that phase of an analysis in which you review the results. Itis probably the most important step in the analysis. Two postprocessors areavailable to review your r esults: POST1, the gen eral postprocessor, and POST26,the time-history p rocessor.POST1 allows you to revi ew the results over t he en tiremodel at specic load steps and sub steps. POST26 allows you to review the

variation of a partito frequency, or w ith respect to s ome ot her r esult points.

GRAPHICS

CREATING GRAPHICS DISPLAYS

You can create many types of graphics displays--geometry displays, resultdisplays, and graphs. Creating any displays is a two step process: rst, you usegraphics specication function to establish specications for your d isplay, then

you use graphics action function to actually produce the displfunctions can be activated either by issuing commands, or by manipulatingspecial menus.

Getting st arted with graphicsCreating geometry displays by using button menus or action commands.Creating geometric results d isplays.Creating Graphs

SELECTING AND COMPONENTS

Select logic is the ability to select subsets of nodes, elements, keypoints,lines,etc. so that you work with a handful of entries. The ANSYS program uses adatabase to store al l the data that you dene during an analysis. This d atabasedesign allows you to se lect only a portion of the data without destroying the restof the data. You can select a subset of entities b y using a combination of seven

basic select functions: senone, and invert.

SUB MODELING

Sub modeling is a nite element technique to get more accurateresults in a region of your model. The procedure for su b modeling consists of the

following steps:Create and analyze the coarse modelCreate the sub modelPerform cut boundary interpolation

Analyze the sub model Verify the sub model

ANSYS PARAMETRIC DESIGN LANGUAGE (APDL)

APDL stands for ANSYS parametric design language which allows you to build your model in terms of et

design changes easily and conveniently. In APDL parameters are user- named variables to which you can assimeri

a numeric eld of an ANSYS command, the value of that parameter will besubstituted.

DESIGN OPTIMIZATION

Design optimization is a technique that seeks to determine anoptimum design. To calculate an optimum design, the ANSYS program performsa series o f analysis a nd the u sual procedure for d esign optimization consists of

six main steps:Initialize th e design variable parametersBuild the m odel parametrically (PREP7)Obtain the solution (SOLUTION)Retrieve th e resu lts d ata parametrically a nd initialize t he st ate

Variable and objective function parameters (POST1/POST26)Declare optimization variables a nd begin optimization (OPT)Review and verify optimum results

Sub structuring

Sub structuring is a procedure that condenses a group of elementsinto one element represented as a matrix. A substructure analysis involves t hreedistinct steps o r pa sses:
