Well, here it is. ANSYS Discovery Live is finally live. And that’s great, because it means we can actually try the software and tell you if it lives up to expectations. After considerable fanfare - some of it our own - we can now put the software to the test. For those of you who missed the build-up, here’s a recap.ANSYS Discovery Live is a GPU-based real-time simulation package that combines CAD modeling simulation environments into one super-responsive arena, where users can view how changes to their designs will affect simulations—in real time. No more meshing. And gone are the days of post-processing.
Post-processing is now just processing! Note, that as Ansys Discovery Live is GPU-based, you will require a GPU to run it.
Ansys recommends a dedicated NVIDIA GPU card based on the Kepler, Maxwell or Pascal architecture (or newer) with at least 4GB of video RAM (8GB preferred). We tested it on a NVIDIA GTX 980, and had no noticeable issues.For this first look, we downloaded the free 15-day trial of ANSYS Discovery Live from the ANSYS website. The trial comes with Discovery AIM and Discovery SpaceClaim, too, in case you want to set up a more in-depth simulation or perform some 3D modeling.Let's just fire up the software and see how far we get without having to resort to reading the instruction manual. This is a good way to test how usable a new piece of software is.
If it’s intuitive, then we don’t need to read the manual, right? ANSYS Discovery Live Wind tunnel simulation.As you can see from the screen shown in Figure 2, the wind tunnel is set up in a confined area with the flow direction being indicated by the green arrow on the left side. The colors on this plot correspond to flow speed, although you can change the plot type by clicking the small menu at the bottom of the screen. The small panel on the left side of the screen shows the data relevant to the simulation, such as gravity, flow speed temperature and any calculations we may have set up.For example, if you want to measure the pressure drag on the front of the cab, you can select the faces of the cabin that you want to take measurements from, and you can switch between these using the menu on the left. Switching from each calculation will display a 2D plot of that information in a small graph on the right side of the screen. In the image shown in Figure 2, you can see three plots, each measuring the pressure on the total wetted area, the windshield, and the wing mirrors, respectively. You can place probes to measure data at any point, too, if you wish.All in all, the plot interface is super easy to use right off the bat, and the same is true for all plot types, be they fluid or solid mechanics based.
But that’s not why we are here.The Design tab is found in the top menu (see Figure 3), and it is here where you can alter the geometry of the model and see how the simulation responds in real time. ANSYS Discovery Live Design tab.For someone coming from a SOLIDWORKS background, their first reaction may be shock as they wonder where all the options have gone. This can be answered by looking at the “Pull” icon. This may not come as a surprise to SpaceClaim users, but all the extruding, cutting and revolving tools to help you convert your sketches from 2D to 3D are accessed via the pull button. Other icons serve dual purposes too, and these can be accessed by clicking the icon while holding CTRL or ALT or some other combination of keys. So that’s where the other functions have gone.

They’re still there; the menu is just a lot less cluttered. It’s deceptively simple at first glance, but after playing with it for a few hours, we learned how deep the functions go. One would definitely have to read the manual (or learn how to use SpaceClaim properly) to become a power user and make the most of this.Next, we switched the plot over to a vortex plot (Lambda2 method) because it looks more psychedelic and fun. You can see that there are a lot of vortices inside the open container at the back (see Figure 4). Winglets on a garbage truck. Design fail, but that’s fine. ANSYS Discovery Live lets you experiment early on in the design process to see what works best.As we can see, the huge winglets have done very little aside from creating even more vortices.
Switching to the pressure plot, we can see that there is additional pressure building around the winglets we added. OK, maybe winglets don’t work on everything.But that’s the entire point of ANSYS Discovery Live. ANSYS wants simulation to become a part of early-phase conceptual design. Sure, you wouldn’t use Discovery Live for a critical bridge design, where the physics need to be verified, but you can get a good idea of how an unusual design (such as winglets on a garbage truck) may affect the efficiency of the product.
It gives you the freedom to explore out-there ideas in the early stages, without the need for meshing or post-processing. That’s a good thing.ConclusionDoes ANSYS Discovery Live live up to the hype?Kinda. In terms of usability and function, it succeeds at the task of making simulation accessible to designers (and not just engineers). It does seem a little limited in terms of the type of calculations available, but if you really want to run more in-depth physics studies, you can always send the file directly to ANSYS Discovery AIM (which is included in both the trial and full versions).
This is a useful design tool, but it is not a design validation tool.More importantly, it’s actually kind of fun to use. It’s almost like a video game, where the player has to reach some particular value by changing model geometry.The gamification of design engineering. That’s a pretty cool thing. We think we will be writing about this software for a long time to come. It will be interesting to see case stories from universities and companies that made the switch to Discovery Live and use it to design products.That will be the real acid test that determines if Discovery Live is just a really cool gimmick or a reality-changing, live-enhancing productivity tool. From our perspective, we think it is the latter.

And that means we may have to read the manual at some point in the future—Discovery Live may be intuitive and the basic modeling may be easy to use, but for sure this software goes way deeper than that.ANSYS Discovery Live is available now, and you can get the trial version.
By DE Editors(Canonsburg, PA) issued a call for papers for the “world’s first” commercial computer-aided engineering (CAE) conference dedicated to the building services industry.The will be held in London, UK, June 5 and 6, 2008, to provide a forum for the application of engineering simulation technology specific to the industry.Presentations are invited from representatives of industry-leading companies to accompany those from ANSYS experts. Papers should highlight innovative and interesting applications using the very latest state-of-the-art simulation technologies in CAE-related disciplines, including computational fluid dynamics (CFD) for airflow modeling and finite element analysis (FEA) for structural studies.Application examples highlighting the use of integrated multiphysics simulation are particularly welcome.
SummaryThe Edifier R1280DB is great bookshelf speaker for its price and the features it comes with. Bluetooth Connectivity IssuesIf the file played is a stored file, the audio is in sync. This might be an isolated issue, and for many of the users of Bluetooth technology, it is known that issues like delay or loss of connection pop up now and then. Edifier r501 remote control instructions. However, the audio suffers some delay and may lag behind when streaming online.
