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 fast incompressible Navier-Stokes solver for non-uniform grids
Pedro Costa, Duarte Palancha, Joshua Romero +2
We present a scalable incompressible Navier--Stokes solver for three-dimensional Cartesian grids with non-uniform spacing. A direct tensor-product--Thomas method solves the constan…
