Two parallel computing methods for coupled thermo-hydro-mechanical problems

Two different approaches are presented for the parallel implementation of computer programs for the solution of coupled thermohydromechanical problems. One is an asynchronous method in connection with staggered and monolithic solution procedures. The second one is a domain decomposition method making use of substriictitring techniques and a Newton-Raphson procedure. The advantages of the proposed methods are illustrated by examples. Both methods are promising, but we actually have no comparison bet\veen the fivo because one works on a linear program with only t\vo interacting fields and the other on a full nonlinear set of (multield) equations. \ua9 2000 Computer-Aided Civil and Infrastructure Engineering.
