A Preconditioner for FETI-DP Method of Stokes Problem with Mortar-Type CR(h)-P0(h) Discretization
FETI-DP method is developed for incompressible Stokes problem discretized by mortar-type CR(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, where H and h are mesh sizes. Finally, the...
