Challenges in the Application of Computer Simulations Models for DesignOptimisation

[摘要] Over the past few decades, there has been tremendous growth in the computing power, both in terms of speed and memorycapacity. Hardware capacities have been increasing ten times every five years, processing power doubles every two years whilethe costs have fallen by one tenth over every five years. Sophisticated simulation models and software have been common placein every engineering discipline. For example, software like ANSYS FLUENT has become the main stay for numerical flow simulation. Parallel computing and cloud or cluster computing technologies have also grown side by side to make computer simulationscheaper with lesser turn-around time. At the same time, with increasing complexity of modern engineering systems, it has also become abundantly necessary, to adopt a global integrated approach right from the beginning, in any major design and developmentprocess. Tight coupling and interaction between different engineering disciplines, besides considerations such as environmental,societal, manufacturing, and reliability constraints are a huge challenge. This has given birth to the area of multi disciplinary optimsation. Above all these, invariably, cost considerations override.
