<\/span>I happen to work for this company who designs, manufactures and sells cars worldwide. You may have heard about this situation where an incident with a car somewhere in the world catches media attention. In such a situation, one has to decide whether the company will have to recall or not its X million vehicles. This has a massive cost but <\/span>imagine the cost of our customer\u00a0security. To better understand the root causes of such an incident, thousands of situations have to be explored, analyzed and this has to be done very quickly; user safety is not an option for us.<\/span><\/p>\nWe don’t know. You are the expert. Explore all the options<\/strong><\/h4>\nMy cup of coffee had barely reached my lips when I heard this ringing phone; it was one of these situations where we had to determine whether the chassis design was the root cause for unbalancing the vehicle leading to poor vehicle dynamics behavior under lateral wind … or maybe it was something else. “We are not sure, hence we need your team to explore all the options”, – in a nutshell, this was the emergency of the day.<\/p>\n
I did call upon my most experienced guys for us to plan how we would address this emergency. Exploring multiple variants, understanding which <\/span>element of the design has failed, reassure our customers of our deep expertise, – or\u00a0recommend to recall vehicles: we needed to act fast, and we don\u2019t have the time to figure this out with physical testing, <\/span>only simulation could help us here.<\/span><\/p>\nOur attack plan was obvious:<\/p>\n
\n- \n
\n- Retrieve the models we had built using Simcenter solutions to support vehicle design<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
\n- \n
\n- Thanks to the company experience, identify the key parameters in the chassis, the controller, the structure as well in the overall\u00a0system which may have led to this incident<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
\n- \n
\n- For each variant of the vehicle range, run the simulation reproducing the scenario and vary the parameters<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
\n- \n
\n- From thousands of simulations, extract the key outcome and draw the conclusion.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Nothing critical for us: one may even say “a walk in the park”… let’s be fair, this would be “a walk in the park on a stormy day”.<\/p>\n

<\/span><\/strong>“A walk in the park”… Yes, assuming we had access to the company HPC. It was about noon, I had already received dozens of calls from many stakeholders watching the news.\u00a0 I had reassured all of\u00a0them: “The situation is under control, we will get simulation results for you by the end of the day”. It was about noon\u00a0when Bob opened the door: “We have a situation, he told me, we cannot run our simulation, the HPC is fully busy for the next week, no way to divert any resources from it”.<\/span><\/p>\n![\"Simcenter-Amesim-Vehicle-Ride-Handling.png\"](\"http:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/6\/2019\/09\/Simcenter-Amesim-Vehicle-Ride-Handling-1.png\" "\\"Simcenter-Amesim-Vehicle-Ride-Handling.png\\"")
<\/span><\/p>\nThe “walk in the park”\u00a0all of a sudden\u00a0turned out to be a “base jump without a suit”.\u00a0Well, Bob is one of these guys who rarely comes with a problem without any solution to propose.

On the other hand, working with Rescale has gone very smooth: on-demand access to their infrastructure happens to be an operational expenditure. And guess what: in such emergency situation, these costs are easily accepted by management.<\/p>\nIn less than an hour, we had access to an online powerful HPC.

Even nicer, thanks to Simcenter on the Rescale platform, we were able to explore additional variants and secure our future answer to such cases.
