This paper presents a hybrid numerical method to solve efficiently a class ofhighly anisotropic elliptic problems. The anisotropy is aligned with onecoordinate-axis and its strength is described by a parameter $\eps \in (0,1]$,which can largely vary in the study domain. Our hybrid model is based onasymptotic techniques and couples (spatially) an Asymptotic-Preserving modelwith its asymptotic Limit model, the latter being used in regions where theanisotropy parameter $\eps$ is small. Adequate coupling conditions link the twomodels. Aim of this hybrid procedure is to reduce the computational time forproblems where the region of small $\eps$-values extends over a significantpart of the domain, and this due to the reduced complexity of the limit model.
