Deflated ICCG method applied to problems with extreme contrasts in the coefficients

Abstract

A Deflated ICCG method is applied to problems with extreme contrasts in the coefficients, such as those encountered in reservoir simulation. Two choices for the deflation vectors are considered. The first one is based on the physics of the problem, whereas the second one is algebraic, and is very suitable for parallel computing. Theoretical and numerical… (More)
