Abstrakt: This report describes selected results achieved by teams from the Technical University of Liberec and Institute of Geonics of the Czech Academy of Sciences within Task 2 of WP 12 DONUT. We present mainly the results focused on modelling, numerical solution and implementation of coupled hydro-mechanical processes in fractured granite-type rocks related to deep geological repositories. In\nparticular, the so-called discrete fracture-matrix approach is used and enriched by selected nonlinear effects on fractures. Within numerical solution of related problems, our results are based on stochastic generation of the fracture network, the mixed finite element method, domain decomposition techniques, splitting procedures and state-of-the-art iterative solvers for linear and nonlinear systems. Open-source in-house libraries are developed and combined to solve the problems. A benchmark in 3D including a borehole excavation in fractured rocks is suggested in accordance with in-situ experiments known from literature and used for illustration of the solution concept. Other achievements of the teams within Task 2 are briefly summarized.
