NASA announced several prizes for speeding up Fortran code in fluid dynamics. https://apple.news/AG75IJsB9Raea_vPLsjjKsw
The software is available to the public for free from NASA’s Software Catalog. https://software.nasa.gov/
The real prize is the software. Who will be the first to use this PLOT3D program for fluid dynamics with a 3D printer. I might build a suspension of one fluid in another to create a spacescape in a fish tank.
