# FiniteVolumeGPU # FiniteVolumeGPU
This is a HIP version of the [FiniteVolume code](#https://github.com/babrodtk/FiniteVolumeGPU) (work in progress). It is a Python software package that implements several finite volume discretizations on Cartesian grids for the shallow water equations and the Euler equations.
