The term Finite Element Analysis (FEA) method is usually associated with solid mechanics. On the other hand, the term Computational Fluid Dynamics is, by definition, fluids oriented. Although both methods works on discretization of geometry based on the idea of chopping space up into small, but finite rather than infinitesimal, spaces or "elements." Then the equations are written that describe what passes through the boundaries of the small space, whether it be force and displacement or flow and pressure.

To dive in details I suggest you to view this finite element analysis book, Finite element analysis pdf (Altair Engineering)

As we all know that there are several types of analysis we do in structures but broadly e=we can classify the types of analysis into two categories implicit & explicit. many young engineers have confusion how they are different in this this blog we know the major difference between them.

Tcl or tool command language is a tool language that can be use to make several hypermesh process automated, I am assuming you understand basic coding and hypermesh. lets see some scripts given below and try to figure out the use of different syntex

There has been a reasearch that in india there are more than 10000 annual accident involves LCV, There are certain government norms that takes care for minimal damage and there are also advanced simulation tools that can be used to simulate govt. norm testing and other possible accident criteria to make vehicle safer in design perspective.

when we are going to model any problem in fea we have to choose which element type we have to use, like 1D , 2D or 3D element, we can solve all type of problems using 3D elements but for sake of simplicity and ease to work we can simplify the problems using 1D or 2D.

Force-A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.

WE CAN CLASSIFY FORCES INTO TWO CATEGORIES

1. CONTACT

2. NON CONTACT

Any geometry that can be defined by its surcace geometry and thickness can be classified into 2D, There are certain characteristics of geometry we have to consider before converting into 2D

1. Having constant thickness

2. Thickness negligible w.r.t. area

3. Assumed no deformation in thickness during simulation

Given below are the examples of 2D simplified geometries

Car-pedestrian accidents account for a considerable number of automobile accidents in

industrialized countries. Head injury continues to be more concerned in Automobile impacts.

Because the head is the most seriously injured part in many collisions including in pedestrian

automobile collisions. Head injuries are the most common cause of pedestrian deaths in car to

pedestrian collisions.

In this blog we are comparing ansys and hyperworks, ansys and hyperworks are two most comprehensive fea packages. They are used in various types of industries especially hyperworks is used in Automotive Industries.
For comparing them we have to understand for application of them,Application may include.

1. Selection of package for particular industry

2. Selection of software as an student who are willing to make career in industry

3. For completion of perticular project.
