Mixed-hybrid discrete fracture model
We present the existence analysis of the hybridization of the lowest order Raviart?Thomas mixed FEM applied to a potential fluid flow problem on a fracture network. The domain, a simple connected system of...

Explicit finite volume scheme for non-equilibrium solute transport
We deal with a model of flow and transport in dual-porosity environment, where the process of solute exchange between mobile and immobile water in blind pores occures [2]. We present a numerical approach for solution of the transport problem based on...

Fast MATLAB assembly of FEM matrices in 2D and 3D: Edge elements
We propose an effective and flexible way to assemble finite element stiffness and mass matrices in MATLAB. We apply this for problems discretized by edge finite elements. Typical edge finite elements
