ABSTRACT
A second order elliptic problem is investigated in domains with complex geometry. The sequence of nonnested finite element triangulations is generated by higher order curved elements. Convergence analysis of the full nonnested multigrid algorithm is done on the basis of a pure isoparametric approach. A numerical example supporting the considered theory is presented.
