CFD Utilities

The CFD Utility Software Library consists of nearly 30 libraries of Fortran 90 and 77 subroutines and almost 100 applications built on those libraries. Many of the utilities apply to multiblock structured grids and flow solutions, but numerous other reusable modules in such categories as interpolation, optimization, quadrature, rapid searching, and character manipulation appear from several decades of software development in the Aerodynamics Division and Space Technology Division at NASA Ames Research Center.
