Abstract

A FETI-DP formulation for three-dimensional elasticity problems on non-matching grids is considered. To resolve the nonconformity of the finite elements, a mortar matching condition is imposed on subdomain interfaces. The mortar matching condition are considered as weak continuity constraints in the FETIDP formulation. A relatively large set of primal constraints, which include average and moment constraints over interfaces (faces) as well as vertex constraints, is further introduced to achieve a scalable FETI-DP method.
