DESCRIPTION:The global magnetic fields of astrophysical and pl
anetary bodies are shaped by the spherical geometr
y of these systems. In this talk\, I will describe
new algorithms for solving nearly arbitrary equat
ions in spherical geometry using the Dedalus frame
work. Users specify equations in plain-text using
vector notation. Each variable is represented in a
spectrally-accurate series expansion of spin-weig
hted spherical harmonics in the angular directions
\, and radially-weighted Jacobi polynomials in the
radial direction. Dedalus can solve equations in
spherical shells\, as well as full balls (extendin
g to r=0). I will provide examples of how to use t
he code\, as well as benchmark problems and speed
comparisons to similar codes.
