Keywords:nuclear safety, fault displacement, surface faulting, high performance computing, parallel computing

We develop a finite element method to which the following two functions are implemented: 1) a rigorously formulated joint element; and 2) a symplectic time integration of explicit scheme to properly conserve the energy. We carry out verification of the developed method solving simple three-dimensional models of a fault embedded in a rock mass.
