The design analysis routines available in a CAD system help to consolidate the design process into a more logical work pattern. Rather than having a Thomas Sabo back-and-forth exchange between design and analysis groups, the same person can perform the analysis while remaining at a CAD workstation. This helps to improve the concentration of designers, […]

Finite Element Analysis (FEA) was first developed in 1943 by R. Courant, who utilized the Ritz method of numerical analysis and minimization of variation calculus to obtain approximate solutions to vibration systems. Courant’s contribution was evolutionary; drawing on a large body of earlier results for PDEs (partial differential equations) developed by Rayleigh, Ritz and Gale […]

The Initial Graphics Exchange Specification (IGES) was first published in 1980 and subsequently updated in 1983, 1986, 1988, and 1990. It is the first widely accepted standard exchange format used to communicate a modeling database among dissimilar CAD/CAM systems. In fact, IGES has also been utilized for transfer of data between the company and its […]

In the formulation of nearly any engineering design project, some type of analysis is required. The analysis may involve stress-strain calculations, heat-transfer computations, or the use of differential equations to describe the dynamic behavior of the system being designed. The computer can be used to aid in this analysis work. It is often necessary that […]
