Perspectives on Reproducibility and Sustainability of Open-Source Scientific Software from Seven Years of the Dedalus Project

Understand

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 differential equation solver Dedalus.

• Dedalus is a flexible framework for solving partial differential equations.
• Its development team primarily uses it for studying stellar and planetary astrophysics.
• Dedalus was developed originally for astrophysical fluid dynamics (AFD), though it has found a much broader user base, including applied mathematicians, plasma physicists, and oceanographers.
