Detailed description

Laghos solves the time-dependent Euler equation of compressible gas dynamics in a moving Lagrangian frame using unstructured high-order finite element spatial discretization and explicit high-order time-stepping. It is built on top of a general discretization library (MFEM) and supports two modes: *full assembly*, where performance is limited by the data motion in a conjugate gradient (CG) solve, and *partial assembly*, where performance depends mostly on small dense matrix operations and the CG solve communication.
