Generalized Tadmor Conditions and Structure-Preserving Numerical Fluxes for the Compressible Flow of Real Gases
Robin Klein, Benjamin Sanderse, Pedro Costa +2
We generalize Tadmor's algebraic numerical flux condition for entropy-conservative discretizations of conservation laws to a broader class of secondary structures, i.e. possibly no…
A GEMM-based direct solver for finite-difference Poisson problems in non-uniform grids
Pedro Costa, Duarte Palancha, Joshua Romero +2
We present a direct Poisson solver for massively parallel simulations on three-dimensional Cartesian grids with non-uniform spacing. The method uses a tensor-based formulation in w…
A pencil-distributed finite-difference solver for extreme-scale calculations of turbulent wall flows at high Reynolds number
Rafael Diez Sanhueza, Jurriaan Peeters, Pedro Costa
We present a computational method for extreme-scale simulations of incompressible turbulent wall flows at high Reynolds numbers. The numerical algorithm extends a popular method fo…
CaLES: A GPU-accelerated solver for large-eddy simulation of wall-bounded flows
Maochao Xiao, Alessandro Ceci, Pedro Costa +2
We introduce CaLES, a GPU-accelerated finite-difference solver designed for large-eddy simulations (LES) of incompressible wall-bounded flows in massively parallel environments. Bu…
