Utilizing Time-Reversibility for Shock Capturing in Nonlinear Hyperbolic Conservation Laws
Tarik Dzanic, Will Trojak, Freddie D. Witherden
In this work, we introduce a novel approach to formulating an artificial viscosity for shock capturing in nonlinear hyperbolic systems by utilizing the property that the solutions…
Bounds Preserving Temporal Integration Methods for Hyperbolic Conservation Laws
Tarik Dzanic, Will Trojak, Freddie D. Witherden
In this work, we present a modification of explicit Runge-Kutta temporal integration schemes that guarantees the preservation of any locally-defined quasiconvex set of bounds for t…
Partially-Averaged Navier-Stokes Simulations of Turbulence Within a High-Order Flux Reconstruction Framework
Tarik Dzanic, Sharath Girimaji, Freddie Witherden
High-order methods and hybrid turbulence models have independently shown promise as means of decreasing the computational cost of scale-resolving simulations. The objective of this…
Reinforcement Learning for Adaptive Mesh Refinement
Jiachen Yang, Tarik Dzanic, Brenden Petersen +9
Large-scale finite element simulations of complex physical systems governed by partial differential equations (PDE) crucially depend on adaptive mesh refinement (AMR) to allocate c…
