Multiple scales analysis of a nonlinear timestepping instability in simulations of solitons
Benjamin A. Hyatt, Daniel Lecoanet, Evan H. Anders +1
The susceptibility of timestepping algorithms to numerical instabilities is an important consideration when simulating partial differential equations (PDEs). Here we identify and a…
Evolution of Semi-convective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets
J. R. Fuentes, Bradley W. Hindman, Adrian E. Fraser +1
Recent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have ``fuzzy" cores, i.e., gradients of the concentration of heavy eleme…
Iterative Methods for Navier--Stokes Inverse Problems
Liam O'Connor, Daniel Lecoanet, Evan H. Anders +5
Even when the partial differential equation underlying a physical process can be evolved forward in time, the retrospective (backward in time) inverse problem often has its own cha…
