ANSYS Workbench Guide - FEA Concepts & Terms explanation

This article would help many of FEA users especially for the beginners,intermediate and advance users.

Everyone knows how important is to understand the fundaments of FEA before they start using any FEA package like ANSYS, NASTRAN etc.,

FEA is simply a tool to better understand how a design will perform under certain conditions. All analysis are approximations accounting for the most significant variables among many. What is almost as useful as obtaining an "exact" answer with regard to "reality", which might take a highly trained specialist a great deal of time performing what is often called a "detailed" analysis, is the trending and behavioral information that can be used to help predict and improve one's design(a basic or fundamental analysis). This approach substantially improves the overall engineering process.

And the whole article will explain about basics of FEA theory, FEA terms etc. Finally you will learnt about How to use ANSYS workbench simulation features. ANSYS workbench simulation is perfectly capable of performing detailed analysis on par with traditional FEA methods in a fraction of the time. For any analysis, detailed or fundamental, it is vital to keep in mind the nature of approximations - study the results and test the final design. Proper use of ANSYS workbench simulation will greatly reduce the number of physical tests required while allowing the designer/engineer/analyst to experiment on a wider variety of design options and improve the end product.

This is not the end of it, you will learn everything about ANSYS Workbench(Brief Tutorial). More importantly one will be in position to understand concepts and basics of FEA theory here.
