Abstract
The context of the paper is finite element solution of transient thermo-elasticity problems, motivated by the global need to simulate the operation of nuclear waste repositories. In this context, the paper deals with large-scale parallel processing of nonstationary heat equations, when the linear systems arising in each time step are solved by the overlapping domain decomposition method. The numerical experiments are performed on a large thermo-elasticity model simulating the behaviour of spent nuclear fuel stored using the Swedish KBS-3 method. The developed parallel codes are based on the OpenMP and MPI standards and their performance is investigated.
