Recent advances have shown that block recursive approximate factorizations provide among the best preconditioners for solving elasticity equations on large 3D meshes such as arising in geomechanical applications. However, to get full efficiency of these methods, a wide range of implementation...

The convergence rate of a numerical procedure based on Schwarz Alternating Method (SAM) for solving elliptic boundary value problems (BVPs) depends on the selection of the so-called interface conditions applied on the interior boundaries of the overlapping subdomains. It has been observed that...
