Gender Disparity in Publishing Six Months after the KITP Workshop "Probes of Transport in Stars"
Meridith Joyce, Jamie Tayar, Daniel Lecoanet
Conferences and workshops shape scientific discourse. The Kavli Institute for Theoretical Physics (KITP) hosts long-term workshops to stimulate scientific collaboration that would…
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…
Tensor calculus in spherical coordinates using Jacobi polynomials, Part-II: Implementation and Examples
Daniel Lecoanet, Geoffrey M. Vasil, Keaton J. Burns +2
We present a simulation code which can solve broad ranges of partial differential equations in a full sphere. The code expands tensorial variables in a spectral series of spin-weig…
Perspectives on Reproducibility and Sustainability of Open-Source Scientific Software from Seven Years of the Dedalus Project
Jeffrey S. Oishi, Benjamin P. Brown, Keaton J. Burns +2
As the Science Mission Directorate contemplates establishing an open code policy, we consider it timely to share our experiences as the developers of the open-source partial differ…
A Validated Nonlinear Kelvin-Helmholtz Benchmark for Numerical Hydrodynamics
Daniel Lecoanet, Michael McCourt, Eliot Quataert +6
The nonlinear evolution of the Kelvin-Helmholtz instability is a popular test for code verification. To date, most Kelvin-Helmholtz problems discussed in the literature are ill-pos…
