This project provides the source code for an AMR FAS multigrid solver for Chombo to complement Chombo's built-in multigrid solver. This AMRFAS solver provides some features not found in Chombo's solver: 1) FAS nonlinear capabilities, 2) a Chebyshev smoother useful for high order discretizations and ... [More] boundary conditions where GSRB is not consistant, and 3) a full multigrid (FMG) cycle. This project also has test code that runs convergance test for this AMRFAS geometric mulgrid solver, Chombo's solver, and a composite grid capability used in conjunction with PETSc's algebraic multigrid (AMG) solvers.
