Learning parameter-dependent shear viscosity from data, with application to sea and land ice
Gonzalo G. de Diego, Georg Stadler
Complex physical systems which exhibit fluid-like behavior are often modeled as non-Newtonian fluids. A crucial element of a non-Newtonian model is the rheology, which relates inne…

Non-Newtonian viscous fluid models with learned rheology accurately reproduce Lagrangian sea ice simulations
Gonzalo G. de Diego, Georg Stadler
Polar sea ice is crucial to Earth's climate system. Its dynamics also affect coastal communities, wildlife, and global shipping. Sea ice is typically modeled as a continuum fluid u…

A note on generating Voronoi cells with a given size distribution
Georg Stadler, Gonzalo G. De Diego
This note describes a simple method to draw random points such that the cells of the corresponding Voronoi tesselation (approximately) satisfy a desired size distribution, for inst…
