High-order Simulation of Nearly Hydrostatic Atmospheric Flows
Shoyon Panday, Stéphane Gaudreault, Carlos Pereira +1
Accurate simulation of atmospheric flows is challenging. Low-Mach-number dynamics often need to be resolved in the presence of a dominant, nearly hydrostatic background state. Conv…

Characteristic Bending in Incompressible Flows
Matthew Blomquist, Stéphane Gaudreault, Maxime Theillard
We present the Characteristic Bending (CB) method, a general framework for advecting quantities under incompressible velocity fields. The method builds on standard semi-Lagrangian…
