# PSAAP3 WENO

Standalone Fortran WENO code with Loopy transformations.

## Notes

1. The WENO scheme is taken from [1]
2. Boundary conditions are not really handled correctly at all
3. For now, the Fortran code will not compile -- the main focus is expressing
   the mathematics
4. Metric conversion routines / all flux arrays everywhere potentially have
   wrong shape
5. A declaration of "real" is not intended to suggest single precision
6. This implementation does not include the severe shock correction proposed
   by [1]
