This paper presents a parallel iterative solution or systems which incorporate the thermo/hydro/mechanical behaviour of unsaturated soil. The approach adopts an iterative solution of the governing equations for the fully coupled analysis in which the primary variables are pore water pressure, pore air pressure, temperature and displacement. The current approach extends this work to problems of greater complexity via a finite element scheme. The developed parallel code was applied to the simulation of a thermo-hydro-mechanical experiment for use in the performance assessment of deep geological repositories for the disposal of nuclear waste. Good speed-ups were achieved, ranging from 1.85 on two processors to 4.71 on 9 processor
