Euler 3D
The CASELab at Oklahoma State is a research group that works with NASA’s Dryden Flight Research Center to study and predict aero-elastic behavior; the interaction between inertial, elastic and aerodynamic forces. One example is flutter – when a lifting surface, such as a wing, oscillates due to aerodynamic forces and structural behavior. A mild flutter might produce a mild buzz in an aircraft, but more severe flutter could destroy an aircraft or other structure: the Tacoma Narrows Bridge collapsed due to flutter induced by a severe wind storm.Euler 3D is an application developed by Tim Cowan and multithreaded by Charles O’Neill, at CASELab for studying and predicting computational aeroelasticity. It is a multi-threaded, floating point and bandwidth intensive computational fluid dynamics (CFD) application. The benchmark data set analyzes the airflow over a specific wing configuration. Thanks go to Scott Wasson of Tech Report for sharing this benchmark with us. One of the nice things about Euler 3D, is that the number of threads is configurable, so that we can investigate how performance and power scale with respect to thread count.
