# Acoustic equations and numerical solvers: PRICE scheme

I am currently very interested in the solution of nonconservative hyperbolic
systems, such as the acoustic equations derived in (LeVeque, 1997). The main
file here implements the primitive centered scheme (PRICE) from (Toro and
Siviglia, 2003).
