CTA Leader: Dr. Roger C. Strawn
The Computational Fluid Dynamics (CFD) CTA covers high-performance computations whose goal is the accurate numerical solution of the equations describing fluid and gas motion, and the related use of digital computers in fluid-dynamics research. CFD is used for basic studies of fluid dynamics for engineering design of complex flow configurations, and for predicting the interactions of chemistry with fluid flow for combustion and propulsion. It is also used to interpret and analyze experimental data and to extrapolate into regimes that are inaccessible or too costly to study. Work in the CFD CTA encompasses all velocity flow regimes and scales of interest to the DoD. Incompressible flows are generally slow, e.g., governing the dynamics of submarines, slow airplanes, pipe flows, and air circulation. Compressible flows are important at higher speeds, e.g., controlling the behavior of transonic and supersonic planes, missiles, and projectiles. Fluid dynamics itself displays some very complex physics, such as boundary-layer flows, transition to turbulence, and turbulence dynamics that require continued scientific research. CFD also must incorporate complex additional physics to deal with many real-world problems. These effects include additional force fields, coupling to surface atomic physics and microphysics, changes of phase, changes of chemical composition, and interactions among multiple phases in heterogeneous flows. Examples of these physical complexities include Direct Simulation Monte Carlo and plasma simulation for atmospheric re-entry, microelectro-mechanical systems (MEMS), materials processing, and magneto-hydrodynamics (MHD) for advanced power systems and weapons effects. CFD has no restrictions on the geometry, and includes motion and deformation of solid boundaries defining the flow.

The Computational Structural Mechanics (CSM) CTA covers the high-resolution multi-dimensional modeling of materials and structures subjected to a broad range of loading conditions including quasi-static, dynamic, electro-magnetic, shock, penetration, and blast. It also includes the highly inter-disciplinary research area of materials design, where multi-scale modeling of different scales from atomistic to macro is essential. CSM encompasses a wide range of engineering problems in solid mechanics such as material or structural response to time- and history-dependent loading, large deformations, fracture propagation, shock wave propagation, isotropic and anisotropic plasticity, frequency response, and nonlinear and heterogeneous material behaviors. High-performance computing for CSM addresses the accurate numerical solution of the conservation equations, equations of motion, equation of states, and constitutive relationships to model simple or complex geometries and material properties, subject to external boundary conditions and loads. CSM is used for basic studies in continuum mechanics, stress analysis for engineering design studies, predicting structural and material response to impulsive loads, and modeling response of heterogeneous sensors/devices-embedded structures. The Department of Defense application areas include conventional underwater explosion and ship response, structural acoustics, coupled field problems, space debris, propulsion systems, structural analysis, total weapon simulation, weapon systems' lethality/survivability (e.g., aircraft, ships, submarines, tanks), theater missile defense lethality analyses, optimization techniques, and real-time, large-scale soldier- and hardware in-the-loop ground vehicle dynamic simulation.
New systems at ARL and ERDC DSRCs will provide an additional 10 petaFLOPS of computational capability.
The Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP) completed its fiscal year 2016 investment in supercomputing capability supporting the DoD Science and Technology (S&T), Test and Evaluation (T&E), and Acquisition Engineering communities. The acquisition consists of three supercomputing systems with corresponding hardware and software maintenance services. At almost 10 petaFLOPs, this procurement will increase the DoD HPCMP's aggregate supercomputing capability to 31.1 petaFLOPs.
The new supercomputers will be installed at the Army Research Lab (ARL) and Engineer Research and Development Center (ERDC) DoD Supercomputing Resource Centers (DSRCs), and will serve users from all of the services and agencies of the Department:
- The Army Research Laboratory DSRC in Aberdeen, Maryland, will receive two SGI ICE X systems containing Intel Xeon "Broadwell" processors and NVIDIA Tesla K40 General-Purpose Graphics Processing Units (GPGPUs). These systems will consist of 33,088 and 73,920 "Broadwell" compute cores respectively, 32 GPGPUs each, 200 and 252 terabytes of memory respectively, 3.5 and 12 petabytes of disk storage respectively, and will provide 1.2 and 2.6 petaFLOPS of peak computing capability each.
- The US Army Corps of Engineers Engineer Research and Development Center DSRC in Vicksburg, Mississippi, will receive a Cray XC40 system containing Intel Xeon "Broadwell" processors, Intel Knights Landing (KNL) Many Integrated Core processors, and NVIDIA Tesla K40 GPGPUs. The system will consist of 126,192 "Broadwell" compute cores, 540 KNL nodes (64 cores each, 34,560 cores total), 32 GPGPUs, 437 terabytes of memory, 16 petabytes of disk storage, and will provide 6.05 petaFLOPS of peak computing capability.
The systems are expected to enter production service in the first half of calendar year 2017.
