My Sandbox

Welcome to the README of my sandbox, this page aims to provide an overview of the projects under /sandbox/Antoonvh/. The main theme here should be geophysical flows. More specifically, I am interested in the atmospheric boundary layer. I hope you can find something that interests you.

Atmospheric Flows


3D Turbulence

2D Turbulence and Vortex Dynamics


Two-Phase flows






Convergence tests

Some tests were carried out to get a feeling for convergence rates when using grid adaptivity.

1D Diffusion (2nd-order accurate multi-grid scheme)
1D Advection (2nd-order accurate Bell-Cotella-Glaz scheme)

1D Poisson problem (2nd-order accurate Multigrid Poisson solver)

Accuracy of the Refinement and Prolongation attributes

More tests


I invested some time in reading the source code to get some additional information on how the tree-grid structure is implemented in Basilisk and how Adaptivity works. To organize my toughts I wrote it down.
