My name is James Neville and I am a simulation engineering here at Autodesk. I want to welcome everyone here today to our webinar, and thank you all for coming out to learn a little bit about the Autodesk simulation. My goal is to ensure that everyone on the call walks away with an understanding of how CDF can be used in the design process, how customers are being successful today, and ultimately how you all can apply our groundbreaking cloud technology to your own engineering challenges to solve faster, solve bigger, solve more. A little bit about myself before we get rolling. I started by career back in working for Blue Ridge Numerics, and Blue Ridge was a technology start-up with a mission of democratizing CFD for design engineers. Back in Autodesk acquired Blue Ridge and added CFdesign to their growing portfolio of simulation products. Autodesk has built a complete portfolio of simulation products over the last 10 years, and we can group these products into two main categories you see here. You got upfront engineering and advanced materials. These tools range from CFD and FDA solutions flow instructional mechanics on the left, all the way to advanced material simulation like plastic injection molding and composites on the right.

You got upfront engineering and advanced materials. These tools range from CFD and FDA solutions flow instructional mechanics on the left, all the way to advanced material simulation like plastic injection molding and composites on the right. What is CFD? CFD stands for computational fluid dynamics. It sounds a lot more complicated than it is. Fluid refers to both liquids and gases, and dynamic simply refers to movement.
A computer is used to perform these calculations, hence the term computational. In short, CFD uses computers to analyze fluid flow and heat transfer problems. In real world terminology you can think of it as a virtual wind tunnel, or a virtual flow bench or a thermal test rig. These programs are considered traditional CFD tools in that they were designed at the PhD level, and are intended to be used at the PhD level. While it solves the same equations as all of the traditional codes, Autodesk CFD is really intended for a different kind of user.
Above all else, there is a sharp focus on automation and user accessibility to allow more users to leverage the benefits of CFD earlier on in product design. And our meshing technology is really no exception here. Fully automated mesh, auto sizing and results based adaptation allow both novice and expert users to obtain accurate, repeatable results with really minimal effort.
You heard me say upfront a second ago. Upfront really refers to a certain point in time in the product development process. Earlier on in product development we have much more opportunity to affect change, and the associated cost of these changes is relatively low. As product development matures more and more items become set in stone, less can be changed, and the cost of any changed dramatically rises.
Upfront simulation means leveraging powerful simulation tools in the design and engineering phase where they have the most value to us. From the ground up, Autodesk CFD is an upfront simulation tool. As a general purpose tool, we find that our customers use Autodesk CFD in literally every industry across the globe.
The tool is really designed to be accessible to all users in all industries. First one here, in the event that your organization encounters say a flow or a thermal challenge, go ahead and pick which method best fits how that challenge would be addressed today. You know classic build, test, fail, built, test fail. Outsourcing, that could be outsourcing it just to solve a problem. I think more and more companies are using CFD these days, bringing it in house as the costs drop.
I think Autodesk moving to a subscription based software delivery has helped that greatly. Thank you for answering that one. Basically, does your organization use the cloud today for product development? That could be collaboration, asset storage, simulation processing. Let me take a look at the answers here. I see the vast majority have reported back no. This is my final poll question. The last one for you. If you think back over the last two years, or even maybe what you had projected for the coming year, about how many unique projects do you estimate could benefit from flow and thermal simulation?
The next one up there is No one at more than Looks like most of it We actually find when we look back over our data from all of our customers over a very long time span, the vast majority of our successful simulation users leverage CFD for four projects per year.
Looks like most folks out there have some projects that could benefit from upfront simulation though. I think it makes sense to go over some of the history of cloud computing at Autodesk to give Cloud Premium some context. Whatever resources were available on a local machine, CFD would utilize to the fullest. Once core counts started to reach 16 and higher we did start to see a bit of a diminishing return with additional resources, but in general CFD solving performance grew linearly with hardware.
As users obtained faster hardware CFD would take advantage of it. If users say upgraded to faster clock speeds or more cores they would see solve speed benefits. However, with just one license, one CFD license, users were limited to solving one job at a time.
But the only real way around this was to purchase additional licenses and additional hardware. A single user with only one license of CFD could solve simultaneously for 10, 50 jobs at one time. No additional license was required, no additional hardware was required. Each job would cost 15 cloud credits, and on demand cloud computing really became the norm for us. Our CFD users essentially had access to on demand remote work stations to solve more jobs in the same amount of time.
Our product development team gave me some conservative numbers last night regarding the total number of simulations submitted since cloud computing arrived for Autodesk CFD five-ish years ago. The number is staggering. Over , jobs since Acquirements like expensive local hardware, heavy laptops having to go back into the office to check on the status of a lengthy overnight simulation.
I can do infinitely more work from this one device than I could do with maybe five or 10 local machines previously because of the power of cloud computing. That brings us to now where Autodesk has just release Cloud Premium, which is more or less our industry leading cloud technology on steroids. Users can now select to have their jobs solved on the traditional cloud or on Cloud Premium.
But standard cloud jobs are solved on a single Amazon EC2 instance with 8 physical cores and provide performance comparable to say a high end local machine. Cloud Premium jobs are different. The list distributed computing network allows for a much faster simulation and enables users to solve jobs previously not possible. Cloud CFD job costs are calculated from a really wide range of variables like model size, requested durations, problem physics, etc cetera.
And Cloud Premium jobs will have a multiplier 4 X. At a median mesh density of say 5 million elements solve time dropped from around three hours to just under one hour. That yields a 3.
When we bump the mesh count up to 11 million elements, which is starting to get pretty large, the solve time drops from 8. With Cloud Premium, this problem was just reduced from a complete work day of time down to basically an extended lunch break. And then finally we arrive at a 30 million element job. This is a very large job. It requires an entire day of Cloud Standard simulation time for completion.
Cloud Premium manages to crank this simulation out 4. The next set of simulations take this performance improvement to a whole nother level entirely. External aerodynamic studies, external flow, these simulations exhibit two properties that typically result in long run times. But the first is just the sheer model size. Often times the mesh required for an accurate solution can be very, very large.
The second is just the number of iterations required for convergence. Due to the number of the complex flow structures, the wake structures, many iterations are typically required to fully resolve the flow field.
Cloud Premium really excels at both of these challenges. At a relatively small mesh size of 1. When we bump the mesh count up to We go from Jumping up to 20 million elements, showed a still amazing 10 X speed up for Cloud Premium. And when we run the numbers on jobs like this, jobs that are this large, they just become staggering.
The plotting these two examples here show how large model sizes previously resulted in lengthy run times of entire work days or even multiple days. They reduced to just a, reduced, excuse me, to just a few hours with Cloud Premium. Gains are expected at most model sizes, but the true value of Cloud Premium is realized when users can reduce their simulation run times from days to just hours.
In general, users can expect a four to five X speed up for most general purpose simulations. Certain applications, like the one I just went over, external flow, they show dramatically greater performance improvements on the order of 10 X or more.
Where are we going with this? Cloud Premium is a very exciting technology for us here at Autodesk. Cloud solving technology is really removed all of those barriers. One of the key advantages to Cloud Premium, one of the advantages that it holds over local solving is that the hardware and software can evolve in real time.
