This document provides an overview of ANSYS 15.0 finite element analysis software. It discusses that ANSYS is an FEA simulation package developed by ANSYS Inc. for performing static, dynamic, thermal, and fluid analyses. It explains the basic logic behind FEA which is to divide a structure into finite elements, apply loads, and solve the system of equations to determine stresses and displacements. The key steps in ANSYS include pre-processing to define the model, materials and loads, solving using an FEA solver, and post-processing results.
