The rudimentary ingredient of engineering and its designing depend on the prototypes. But for a car, phone, laptop, rocket, and aircraft, it is simply not possible to make a dozen of prototypes just for the sake of determining the impeccable designing. It will not only incur an immensely colossal cost, it'll also stretch the production time. With exordium of digital design and virtual simulation, production cost, design cost and production time, these all three will drop. Since, perfect design of these products depends on the multi-physics – Structure, Air flow and Electro-magnetics, it is paramount to get these to a digital simulation in a virtual environment and determine which design works better or impeccably optimized.

In the earlier days, engineers used to follow just mono-physics for simulation. But in the absence of multi-physics simulation, the chances of error increase by at least 20 percent. So now, virtually every company is following multi-dimensional simulation to increase the productivity, eliminate the peril of errors involved and eventually laying down the production time.

What according to you are the best practices of Engineering Simulation?
It was said that every engineer will utilize simulation software. But, in 2000, there was only one simulation engineer out of every 22. With a slow but steady transmutation in the market, now there is one simulation engineer out of every five. So people have apperceived the consequentiality of simulation and now in companies like Larsen & Toubro, there is one simulation engineers out of every eight engineers. We at ANSYS believe, by the cessation of 2015, every engineer is going to use simulation because high-end and sophisticated designs are only possible through simulation engineers. At the early stage of product development, designers will complete basic simulations. The second trend is multi-physics analysis. Anteriorly, only qualified and PhDs in simulation could understand simulation, but now even a person without any PhD in simulation can understand that if a phone is getting sultrier, maybe it's a design fault or contravening the rules of physics.

The third trend is how we do system engineering. If we visually examine the large OEMs, they're becoming more prone to system integrating. They're now just into concept designing and the suppliers are doing the rest – manufacturing the components. Now, simulation is done at individual component level – engine level, chassis level, steering level and such others. The fourth trend is Cloud computing. Simulation is one of the colossal data generators and it requires maximum processing. People are not establishing extravagant processing clusters as they're extravagant. Instead, they're using cloud. The latest trend that we have witnessed is Internet of Things. Big companies are introducing trends like connected cars, self-driving cars through our very own IoT.
