Abstract
The aim of the paper is to compare the rates of iteration convergence of two staggered numerical schemes: one using successive substitutions and the Ether the Newton method. In the case of very weakly coupled p roblems the Newton method is one order faster, but there are specific cases when it is slower than the standard staggered algorithm. In both cases a convergence condition must be verified. The behaviour of the investigated staggered procedures in case of thermo-hydro-mechanical p roblems are shown on examples.
