The contribution is motivated by the need for numerical analysis of flow in fractured porous media, i.e. rocks in the geo-engineering applications. We describe development and testing of numerical methods for simulation of (coupled) flow and deformation in a fractured porous environment. The hydraulic behavior is described by the Darcy flow in the porous matrix and the Poiseuille flow in the fractures. The fractures are considered as domains of reduced dimension. Both the matrix and fracture flow are interconnected by the flux through the fracture walls. The mechanical behavior is described by the linear elastic deformation of the porous matrix with contact conditions on fractures. In this way, it allows fracture opening and closing with the constraint on non-penetration. The slip effects are not considered. We consider both steady-state and time-dependent problems.
