In many applications, one wants to model physical systems consisting of twodifferent physical processes in two different domains that are coupled across acommon interface. A crucial challenge is then that the solutions of the twodifferent domains often depend critically on the interaction at the interfaceand therefore the problem cannot be easily decoupled into its subproblems.Here, we present a framework for finding robust preconditioners for a fairlygeneral class of such problems by exploiting operators representing fractionaland weighted Laplacians at the interface. Furthermore, we show feasibility ofthe framework for two common multiphysics problems; namely the Darcy-Stokesproblem and a fluid--structure interaction problem. Numerical experiments thatdemonstrate the effectiveness of the approach are included.
