Implemented a preconditioner for the implicit E-field solve using the AMReX curl-curl operator and the MLMG solver.
Preconditioner
base class that defines the action of a preconditioner for the JFNK algorithm.CurlCurlMLMGPC
that uses the multigrid solution for the curl-curl operator (implemented inAMReX
) to precondition the E-field JFNK solve.Other changes needed for this:
ImplicitSolver
class that allows preconditioners to accessWarpX
info (likeGeometry
, boundaries, etc).Some premilinary wall times for:

32^2
particles per cell:with
