An incomplete factorization iterative scheme with ORTHOMIN acceleration is evaluated for threedimensional finite element applications. Both heat conduction and combined heat and fluid flow are investigated. Computational efficiency is investigated for both linear (8 node) and quadratic (27 node) ele
We propose new block incomplete factorization preconditioners for a symmetric block-tridiagonal M-matrix which can be computed in parallel, and then theoretical properties for these block preconditioners are studied. Spectral properties of the transformed coefficient matrices with the block incomple
