Surya
Implementation of the Surya Foundation Model for Heliophysics
Surya is an open‑source, AI‑based foundation model for heliophysics developed collaboratively by NASA (via the IMPACT AI team) and IBM. Named after the Sanskrit word for “sun,” Surya is trained on nine years of high‑resolution solar imagery from NASA’s Solar Dynamics Observatory (SDO). It is designed to forecast solar phenomena—such as flares, solar wind, irradiance, and active region behavior—by predicting future solar images with a sophisticated long–short vision transformer architecture,... -

ransfoil
console to calculate airflow around an airfoil based on RANS approach
RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and... -

Jljp
Calculates the voltage across a liquid junction between two solutions
An analogous project written in C# can be found here: https://github.com/swharden/JLJP Liquid junction potential calculator. It's a tool for scientists and engineers who have to do with electrochemistry and electrokinetics. When two solutions containing ions are put into contact, possibly through a porous diaphragm, a voltage develops across them. The calculation of the voltage is not trivial. The program is written in Java. Includes classes that can be included in other programs, together with graphical interfaces (also as an applet). -
