Mechanical Engineering Softwares

Today mechanical engineering is related closely to engineering softwares. With these softwares, mechanical engineers can quickly do complex computation and simulation. Also, if you need to change a plan, you can do it quickly by the use of mechanical softwares.


CATIA was used for the first time in 1977 by France Air (Avions Marcel Dassault) for development of mirage fighters. Then was used in the aerospace, automotive, and ship building, as “Conception Assistée Tridimensionnelle”. This software was renamed CATIA in 1981 and is now one of the most popular softwares in various fields of mechanics.

In 1984, Boeing decided to use CATIA V3 as the original software of mechanics. In 1990 America shipyard used the software for designing of a warship. In 1998, CATIA Version 5 was introduced. And so in 2008 and 2010 and 2012, the next more advanced version of the software was developed.


A full three-dimensional software for designing, simulating and collecting of designed information. Features of this software helps mechanical engineers to design parts, faster and easier. And with the cooperation of different parts and with speed and accuracy, produces cost-effective products. SOLIDWORKS is one of the leading softwares in the mechanical field that covers almost all needs of the engineers. SolidWorks is a production of a company with the same name that is being subset of Dassault System _ Producer of CATIA _ for recent few years.

The software consists of three major sections that each section have their own task. These sections includes:

“Part” to create pieces

“Assembly” to assembly created

“Drawing” to create a two-dimensional map of projects


In 1972, David Hibitt, presented his doctoral thesis entitled computational mechanics based on the finite element method at Brown University. Doctor Hibitt after working for a long time in an analysis and research company that named “Mark”, left the company and founded ABAQUS software in 1977. In 1978, doctor Hibitt with his two partners, namely Karlsson and Sorensen founded a company called HKS and published the first edition of ABAQUS.

Their first client, was Westinghouse Hanford (manufacturer of nuclear reactors). Ability of ABAQUS in simultaneous analysis of temperature, plasticity, and contact, makes the software to be use in the nuclear industry.

Another early use of the software, is modeling of petroleum Pier Sea. Also large automobile companies are using ABAQUS for their advanced design.

After many years, the HKS Company completed its original finite element software as ABAQUS Standard. In 1991, ABAQUS CAE was published by this company for pre-processing and post-processing operations.


This application was published for the first time in 1970 by Doctor John A. Swanson as Swanson Analysis Systems (Inc. SASI). The first target of this system, was development of finite element analysis software for physical structures that had ability to simulate static, dynamic and heat transfer. In 1994 the company was sold to TA Associates and since then was released as ANSYS.

ANSYS modeling capabilities are include:

  • two-dimensional, three-dimensional, two-dimensional axisymmetric, two-dimensional axisymmetric with rotation
  • Mesh square, triangular, brick (Hexa_Hedral), tetrahedron, pyramidal, multi-faced
  • Stable or unstable flows
  • Compressible and incompressible flows, including all ranges of speed (subsonic flow, Transonic flow, supersonic flow)
  • Non-viscous, laminar, turbulent flows
  • Newtonian and non-Newtonian flows
