摘要：
The newly introduced Locally Exact Algebraic Preconditioner (LEAP) is combined with the well established FETI-DP method to provide robust and scalable iterative convergence. This is achieved by adopting a single-level version of LEAP, sufficient to deduce scalable results due to treatment of domain-edges by FETI-DP. It is experimentally shown that the LEAP can significantly improve the order of convergence of FETI-DP to make it more efficient and robust.
