We are interested in fast domain decomposition solvers for multi-patch Isogeometric Analysis (IgA; [4]). We focus on variants of FETI-DP solvers, see [2, 10] and references therein. Such methods have been adapted to IgA in [5], where the individual patches of the multi-patch discretization are used as subdomains for the solver. This method is sometimes referred to as the dual-primal isogeometric tearing and interconnecting (IETI-DP) method.
