A Comparison of Consistent Discretizations for Elliptic Problems on Polyhedral Grids
(Chapter, 2020)In this work, we review a set of consistent discretizations for second-order elliptic equations, and compare and contrast them with respect to accuracy, monotonicity, and factors affecting their computational cost (degrees ... -
Data Assimilation for Ocean Drift Trajectories Using Massive Ensembles and GPUs
(Chapter, 2020)In this work, we perform fully nonlinear data assimilation of ocean drift trajectories using multiple GPUs. We use an ensemble of up to 10000 members and the sequential importance resampling algorithm to assimilate ... -

Reducing Numerical Artifacts by Sacrificing Well-Balance for Rotating Shallow-Water Flow
(Chapter, 2023)We consider the problem of rotational shallow-water flow for which non-trivial rotating steady-state solutions are of great importance. In particular, we investigate a high-resolution central-upwind scheme that is well-balanced ...
