| Abstract: | A parallel stochastic FEM based on PC cluster is designed by combining Monte-Carlo stochastic algorithm and domain decomposed finite element method. Making a random field as a sample, exerting the virtues of parallel FEM, huge computing capacity and fast computing, the long time consuming disadvantage of Monte-Carlo method is conquered. Developed parallel computing program using C++ and MPI, then the reliability of a slope is analyzed with 1 000 stochastic samples; and the robust and efficiency of this algorithm are validated. |
