Simulation Before Prototyping

Apart from cost savings, the second biggest advantage of simulation is the level of detail that you can get from simulation. Simulation can give you results that may not be experimentally measurable with our current level of technology or available instruments in hand”

Besides, design firmsbenefitfrom time-to-market reduction and savings on expensive resources. Since many tests may call for destructive mechanism, costly components cannot be used frequently. Simulation helps to save a lot on that part. It also saves a lot of time in re-iterations being done physically and thus improves time-to-market.

Addressing system complexity
With system complexity increasing rapidly, and in some cases even exponentially, simulation models that capture and mirror the behaviour of systems have also become extremely large.

“Simulation models are increasingly being used to communicate and share design specifcations between project partners or between original equipment manufacturers (OEMs) and suppliers. Large corporations are using model-based design across product development processes spanning development and application centres across the globe. To collaborate, they have really large models—some with millions of blocks that are created or assembled by hundreds of engineers. A simulation environment has to be able to handle huge models that are developed by hundreds of engineers from diverse domains across geographically dispersed markets,” explains Rao.

Virtually every organisation is facing challenges to make equipment that are more energy-efficient than their predecessor. I remember talking to a key executive from a product manufacturing company, who said that today he has to build a product that has half the size and twice the rating of those made a mere five years ago”

The new MATLAB Desktop features a Toolstrip that puts key features and commonly-used functionalities up-front, a gallery of pre-built MATLAB apps, and tools that enable customers to create and share apps of their own. Simulink platform for model-based designs now features the capability to step through as well as rewind a simulation. Stateflow also incorporate the capability to create state-transition tables and use MATLAB as the Action Language.

As far as energy is concerned, virtually every organisation is facing challenges to make equipment that are more energy-efficientthan their predecessor.

“It should take up less energy and do more work. I remember talking to a key executive from a product manufacturing company, who said that today he has to build a product that has half the size and twice the rating of those made a mere fiveyears ago. That’s the kind of challenges energy and rotor machinery manufacturers and product developers are facing,” explains Dutta.

The industry has grown such that an engineer might have to work with a multi-disciplinary approach to successfully deliver cutting-edge products. Simulation tools now feature add-on modules that enable engineers to speed things up.

When working on a product, you do not want to spend a lot of time learning a new software and ensuring what you have built in your software is accurate. So we have add-on modules where we do all the customisation for our customers. Then they can use these models and very quickly come up with solutions that they are looking for”
