Hybrid-Delta Tracking on a Structured Mesh in MCATK
J. P. Morgan, Travis J. Trahan, Timothy P. Burke +2
Monte Carlo Application Toolkit (MCATK) commonly uses surface tracking on a structured mesh to compute scalar fluxes. In this mode, higher fidelity requires more mesh cells and iso…
Accelerating reactive-flow simulations using vectorized chemistry integration
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
The high cost of chemistry integration is a significant computational bottleneck for realistic reactive-flow simulations using operator splitting. Here we present a methodology to…
Using SIMD and SIMT vectorization to evaluate sparse chemical kinetic Jacobian matrices and thermochemical source terms
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
Accurately predicting key combustion phenomena in reactive-flow simulations, e.g., lean blow-out, extinction/ignition limits and pollutant formation, necessitates the use of detail…
Accelerating solutions of one-dimensional unsteady PDEs with GPU-based swept time-space decomposition
Daniel J Magee, Kyle E Niemeyer
The expedient design of precision components in aerospace and other high-tech industries requires simulations of physical phenomena often described by partial differential equation…
