Argonne Lab Conducts Groundbreaking Simulation of Flow Inside Combustion Engine

At Argonne National Laboratory, Ginger Reilly writes about the achievement of a key milestone: scientists across Argonne have collaborated on the largest-ever simulation of flow inside an internal combustion engine. The work was done on the Theta system, with calculations performed using Argonne’s fluid-thermal simulation code, Nek5000, which was recognized with the Gordon Bell prize for its outstanding scalability on high-performance parallel computers in 1999. A new version of Nek5000, called NekRS, is being developed for accelerator-based machines by the Center for Efficient Exascale Discretizations, one of six co-design centers within the US Department of Energy’s Exascale Computing Project.
