Analysis simulation & the design process

A rapid increase in the use and application of analysis simulation has occurred. With increasing power of computers and relative decreasing hardware costs, the use of these methods within the design process has become more common. Finite element analysis is typical of many advanced analysis tools such as computational fluid dynamics, boundary methods and control simulation and is used as an example. The finite element method is within easy reach of most engineers performing day to day tasks. Now that such analysis methods are more freely available to engineers, they need to be aware of the possible stumbling blocks they are likely to encounter which will influence both analysis timescales and costs. Some `at the coalface analysis´ guidelines have been developed based on experience gained in using the finite element method closely linked with the design process. The guidelines are categorised as follows: general ground rules, analysis choice, upgrades, input, (preprocessing), computer resources, output, (post-processing), software integration, training and risks
