LULESH-Accelerate

=================

Implementation of the Livermore Unstructured Lagrangian Explicit Shock

Hydrodynamics (LULESH) mini-app using [Accelerate][accelerate].

[LULESH][lulesh] represents a typical hydrodynamics code such as [ALE3D][ale3d],

but is a highly simplified application, hard-coded to solve the Sedov blast

problem on an unstructured hexahedron mesh.
