FETI-DP method is developed for incompressible Stokes problem discretized by mortar-typeCR(h)−P0(h)mixed elements. A preconditioner is proposed, and it is proved that the condition number of the preconditioned FETI-DP operator is bounded by(1+log(H/h))2, whereHandhare mesh sizes. Finally, the numerical tests are presented to verify the theoretical results.
