Ansys Tutorial, INTRODUCTION

ANSYS is a general purpose finite element modeling package for numerically solving a wide variety of mechanical problems. These problems include: static/dynamic structural analysis (both linear and non-linear), heat transfer and fluid problems, as well as acoustic and electro-magnetic problems.
In general, a finite element solution may be broken into the following three stages. This is a general guideline that can be used for setting up any finite element analysis.

Preprocessing: defining the problem; the major steps in preprocessing are given below:
Define keypoints/lines/areas/volumes
Define element type and material/geometric properties
Mesh lines/areas/volumes as required
The amount of detail required will depend on the dimensionality of the analysis (i.e. 1D, 2D, axi-symmetric, 3D).
Solution: assigning loads, constraints and solving; here we specify the loads (point or pressure), contraints (translational and rotational) and finally solve the resulting set of equations.
Postprocessing: further processing and viewing of the results; in this stage one may wish to see:
Lists of nodal displacements
Element forces and moments
Deflection plots
Stress contour diagrams.
