The Magnetorotational Instability Prefers Three Dimensions
Jeffrey S. Oishi, Geoffrey M. Vasil, Morgan Baxter +4
The magnetorotational instability (MRI) occurs when a weak magnetic field destabilises a rotating, electrically conducting fluid with inwardly increasing angular velocity. The MRI…
Dedalus: A Flexible Framework for Numerical Simulations with Spectral Methods
Keaton J. Burns, Geoffrey M. Vasil, Jeffrey S. Oishi +2
Numerical solutions of partial differential equations enable a broad range of scientific research. The Dedalus Project is a flexible, open-source, parallelized computational framew…
The "Sphered Cube": A New Method for the Solution of Partial Differential Equations in Cubical Geometry
Keaton J. Burns, Daniel Lecoanet, Geoffrey M. Vasil +2
A new gridding technique for the solution of partial differential equations in cubical geometry is presented. The method is based on volume penalization, allowing for the impositio…
Improving convergence of volume penalised fluid-solid interactions
Eric W. Hester, Geoffrey M. Vasil, Keaton J. Burns
We analyse and improve the volume-penalty method, a simple and versatile way to model objects in fluid flows. The volume-penalty method is a kind of fictitious-domain method that a…
A sparse spectral method on triangles
Sheehan Olver, Alex Townsend, Geoff Vasil
In this paper, we demonstrate that many of the computational tools for univariate orthogonal polynomials have analogues for a family of bivariate orthogonal polynomials on the tria…
Predicting the Rossby number in convective experiments
Evan H. Anders, Cathryn M. Manduca, Benjamin P. Brown +2
The Rossby number is a crucial parameter describing the degree of rotational constraint on the convective dynamics in stars and planets. However, it is not an input to computationa…
