About ansys 15.0

Version - ANSYS 15.0 Is a FEA simulation package Developed by ANSYS Inc-USA ISO 9001:2000 Company Product – ANSYS Metaphysics More than 4,50,000 customers

Objectives CAD/ CAE Introduction to Simulation A comprehensive discussion on FEA

(Finite Element Analysis) & FEM (Finite Element Method)

Performing Finite Element Analysis using ANSYS

What is the logic? Divide body(or structure) into finite

number of units known as elements Study the response of individual

element for different loading conditions

Develop a mathematical model Total response of the object is the

sum of individual responses of the elements

How does ansys work?

Pre Processor

FEA Solver

Post Processor

Operation Sequence used in ANSYS

Pre-processor Create solid model Create FEA model Define Material Properties Element Types Meshing (Free or Mapped) Loads & Boundary Conditions

FEA solverFunction of the solver is to solve the

system of linear simultaneous equations

Form stiffness matrix for each element

Assemble the global stiffness matrix Solve matrix equation Find displacement Calculate strain & stress

Postprocessor To review results of the analysis Two postprocessors: 1) General Postprocessor 2) Time-History Postprocessor Represented in the form of a table,

graph, contour plot, deformed shape or mode shapes of component & animation
