Let A be a linear elliptic operator of the second order with bounded measurable coefficients on a bounded open set Ω of Rn , and let (Ωh) be an arbitrary sequence of open subsets of Ω. We prove the following compactness result: there exist a subsequence, still denoted by (Ωh) , and a positive Borel measure μ on Ω, not charging polar sets, such that, for every f ∈ H−1(Ω) , the solutions uh ∈ H1 0 (Ωh) of the equations Auh = f in Ωh , extended to 0 on ΩΩh , converge weakly in H1 0 (Ω) to the unique solution u ∈ H1 0 (Ω) ∩ L 2 μ(Ω) of the problem
