Abstract
An efficient multigrid approach for solving a discretized elliptic equation whose boundary values are determined in part by integral relations is deve loped, analyzed, and tested. The algorithm is motivated by a problem that i s solved during integration of the 3D quasigeostrophic (QG) equations, whic h model large-scale rotating stratified flows, where the integral constrain ts represent mass conservation.
