omputers have been used to carry out physics-based simulations to predict the performance of a product
for more than 40 years. Yet during this time simulation has generally been seen as complex, expensive and the work of experts. Only very large companies have been able to afford to hire full-time simulation specialists to develop methods to apply to their particular products. There have been attempts to
introduce simulation to non-experts, but CAD operators are not trained to calculate the engineering evaluations involved and the tools were only able to carry out simple linear analyses on single components. Consequently, simulation experts
rejected them as over-simplified and their view was backed by the fact that parts that had been verified by these tools sometimes failed the final validation tests. There were
New products DIAdem 2012
DIAdem 2012, the latest version of the software tool specifically designed to help engineers and scientists share and interpret data, has been announced by National Instruments. Optimised to operate on large data sets, it is a single, unified software environment that the company says makes engineers and scientists more efficient when locating, inspecting, visualising, analysing and reporting
on data. In addition to engineering- specific analysis functions, DIAdem 2012 features a powerful drag-and- drop report editor and runs scripts for automating repetitive tasks. Reporting features include improved performance of multipage report layouts, an object- oriented VBScript API for automating reports and scalable background images for 2D charts.

examples of success, but only for those organisations that were prepared to invest in training, standardising processes and generally work hard to force the technology to fit their needs. Many manufacturers and product designers have, therefore, continued to use specialists and handle simulation in an inefficient serial design-prototype- test-redesign cycle. At the same time, the search has continued for a way to enable designers and engineers to perform these tasks as part of their day-to-day work. Recently, several factors have come together to create a breakthrough. The integration of intelligent 3D modelling technology with multi-physics simulation makes simulation-driven design early in a product development process a reality. This can have an enormous impact on product cost, quality and development time. For example, by bringing finite element analysis (FEA) and mechanical event simulation (FEA)

in house as part of its Autodesk digital prototyping solution, snow vehicle manufacturer, the Tucker Sno-Cat Corporation, slashed both time and cost for design validation by between 50 and 60 per cent. However, as product complexity continues to grow, more and more computing power is needed to perform multi-physics analyses and this can exceed the scope of the desktops and workstations used by most engineers and designers. Fortunately, this is a shortfall that new cloud technology can fill, enabling users to maximise the use of simulation-driven design.
Engineers no longer have to spend time simplifying geometry prior to analysis, the infinite computing power available in the cloud means they can now perform complex multiple pre- processing or multiple simulation tasks in parallel. The software automatically acquires all the appropriate geometry and inputs, such as limits and parameters, and then transfers the information to the HPC in the cloud. This performs the meshing, executes the necessary solvers, runs the appropriate post processor and then returns the results to the user. l To read the full article, please visit

FDTD Solutions 8.0
Lumerical Solutions has announced the launch of FDTD Solutions 8.0, the nanophotonic design environment based on the finite- difference time-domain (FDTD) technique. This latest release extends the material modelling capabilities of prior versions to include the ability to model liquid
crystals and other spatially-varying anisotropic materials. Also present is a Flexible Material Plugin (FMP) framework that enables researchers to model a wide variety of other materials, including nonlinear, magneto-optical and saturable gain materials.
