The concern of this work is the generalization of an Asymptotic Preservingmethod for the highly anisotropic elliptic equations presented in [P. Degond,A. Lozinski, J. Narski, and C. Negulescu. An asymptotic-preserving method forhighly anisotropic elliptic equations based on a micro-macro decomposition. J.Comput. Phys., 231(7):2724{2740, 2012]. The limitations of the methodintroduced there in are omitted by the introduction of a stabilization term inthe Asymptotic Reformulation. Furthermore, anisotropic error indicators andmesh adaptation algorithms are proposed and tested allowing to reduceconsiderably the number of mesh points required to achieve prescribedprecision. Reported meshes have maximum aspect ratio greater than 500.
