The project will facilitate the development of a parallel code for solving hyperbolic partial differential equations in 3D. Particular attention will be given to the Euler equations and the second order wave equation, modelling sound propagation in the atmosphere. The equations are solved using energy stable and highly accurate schemes based on high order finite differences. Relatively small problems will be considered in the current project. In the long-term future the code developed here will be extended to a wider array of PDEs and used for large simulations.
