ALECG for a PDE system with continuous Galerkin + ALE + RK.

Contents

ALECG advances a system of partial differential equations (PDEs) using a continuous Galerkin (CG) finite element (FE) spatial discretization (using linear shapefunctions on tetrahedron elements) combined with a Runge-Kutta (RK) time stepping scheme in the arbitrary Eulerian-Lagrangian reference frame.

There are a potentially large number of ALECG Charm++ chares created by Transporter. Each ALECG gets a chunk of the full load (part of the mesh) and does the same: initializes and advances a number of PDE systems in time.

The implementation uses the Charm++ runtime system and is fully asynchronous, overlapping computation and communication. The algorithm utilizes the structured dagger (SDAG) Charm++ functionality.
