The ultimate benefit of digital simulation is being able to manipulate each and every parameter for a given issue: this is what we did for the travel of the iceberg. The transportation operation could be repeated as often as necessary by fiddling with the relevant parameters.

Considerable progress has been made in meteorology and oceanography. Forecasts have been available, providing detailed information about currents and their temperature, speed, eddies or whatever weather and sea conditions.

This vital information makes it possible to optimize towing operations, taking advantage of favourable conditions or, conversely, avoiding unfavourable ones.

Indeed, it is pointless for the iceberg convoy to try and take on natural forces if these are too overpowering. It only leads to increased fuel consumption. When your objective is  to provide water at a lower price and with a reduced carbon footprint, it is for sure not the right way to go!

Let me give you one very concrete example. Can you imagine a giant eddy, 200km wide or more? Basically, two drastically different situations can happen when the convoy meets one:

  1. Either the eddy takes you to the right direction with respect to the final destination. As such, the convoy clearly benefits from its power.
  2. Or, the eddy takes you to a direction you don’t want to go. In such case, it is useless for the boat to try and struggle against the eddy force.

That’s where the simulation comes in handy: it teaches you what the most appropriate steering strategy is for each situation encountered on the convoy’s route, and in the case of eddies, how to leverage them.

This was actually one of Mougin’s key ideas we had to check: the assisted drift approach, which works by exploiting the iceberg’s natural drift and the prevailing currents!

Harnessing the power of the prevailing currents means transporting the iceberg “with no actual [towing] effort, as if the water had become one enormous conveyor belt.

The engineering team used real data of a reference year to build the drifiting simulation: that way, they were able to observe and analyze as many phenomena as possible, including eddies and the way they could be exploited to save significant time and fuel.

What does this mean? Less time and less energy consumed, that is less money spent… and cheaper water!

Best,

Cédric

Here is the exclusive information of the day: Dassault Systèmes will hold its Application Innovation Summit on June 28th and 29th at the Espace de la Grande Arche de la Défense in Paris. It aims at engaging executives and R&D teams around the Version6 open platform.

And guess what? Your fellow blogger (um, me) will be there to give you live feedback! :-) I’ll be blogging and tweeting and interviewing during the summit. Of course, if you’re there, it’ll be a pleasure to have a chat!

Meanwhile, if you have any question you’d like to ask, please do so in the comment section and I’ll make sure I answer them by the end of the summit.

See you there!

What’s all the Noise (& Vibration) about?

The first time I heard the term “N&V” it confused me a little, mostly because it’s an acronym, but partially because it’s related to cars and vehicles. “What’s this ‘N&V’ got to do with cars?” I wondered.

It turns out that Automotive OEMs spend a lot of time thinking about what noises their cars will make and how that affects your experience! And it’s true that I hate it if a car has an annoying rattle or squeak! But I never really understood what that meant in terms of car design.

Recently one of my colleagues showed me a presentation that so beautifully illustrated what Noise and Vibration is all about, that I thought I should share it with you:

You’ll also notice that this video not only explains very clearly why Noise and Vibration is important to car manufacturers , but it also explains what an amazing job our R&D team has done to improve the way we realistically simulate N&V for vehicles.

In fact, they have done such a good job, that we’re showing them and our technology off, at the SAE Noise and Vibration conference this May, in Grand Rapids, Michigan.

Hopefully, we’ll see you there!

Cheers,

Tom
