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…

Topographic Effects on Steady-States of Non-Rotating Shallow Flows
Pierpaolo Bilotto, Roberto Verzicco
In this work, we discuss the long-time behavior of non-rotating quasi-2D viscous flows over topographies. We develop a novel theoretical and numerical framework for the analysis of…
