Analytical techniques have long been established as essential tools in design engineering and have, in many cases, been incorporated into analytical models that facilitate the testing of new design and design concepts without the time and expense of building physical models. The cost of changing a design increases dramatically after it is committed to production and subsequently increases at a higher rate after it is in service. Use of analytical models enables economical testing and optimization of multiple design concepts before commitment to production and/or service, thus significantly increasing the confidence in the performance of an engineering component, assembly or system and decreasing the cost of system application and implementation.
