The application of computers to design analysis has improved product knowledge. This paper discusses two applications of computer-aided design analysis that improves the productivity of engineers and analysts. The first application discussed is that of structural boundary elements. In the last few decades domain discretization techniques such as the finite element method have been used extensively for design analysis. Surface discretization techniques such as the boundary element method offer significant advantages over the finite element method in terms of modelling effort required and relative accuracy achieved for a given mesh density.The second application is the solution of inverse thermal problems. This technique aids in the determination of temperature distribution of a component, given some experimentally obtained temperature data.
