This video shows a high-resolution CFD simulation of Rayleigh-Bénard convection, which occurs when a fluid layer is heated from the bottom and cooled from the top. These thermally driven fluid flows are all round us – from windy days, to lake effect snowstorms, to magma currents in the earth’s core and plasma movement in the sun.
This simulation was created using the WSE Field-equation API (WFA) developed by the Department of Energy’s National Energy Technology Laboratory (NETL), and run on the NSF-funded Neocortex system at the Pittsburgh Supercomputing Center (PSC),
As the narrator of this video from NETL says, it’s not just the visual beauty of the simulation that’s important: it’s the speed at which we’re able to calculate it. For the first time, using our Wafer-Scale Engine, NETL is able to manipulate a grid of nearly 200 million cells in nearly real-time.
By transforming the speed of CFD, which has always been a slow, off-line task, we can open up a whole raft of new, real-time use cases for this, and many other core HPC applications. To quote the video again: “More compute power, more experiments, better science!”
