Pyranda Overview

Pyranda is a mini-app for the Miranda Code developed at Lawrence Livermore National Laboratory. Pyranda is a python extension and is a library designed to solve Hyperbolic systems of PDEs on structured grids with a high-order finite difference method.

Pyranda solves systems of PDEs (operators, algebraic closures, boundary conditions, initial conditions) are described in simple mathematical text. Problems can therefore, be quickly setup and models prototyped by simply writing them down.
