Modelling urban floods using a finite element staggered scheme with an anisotropic dual porosity model

A mixed finite-element scheme of a semiconductor energy-transport model using dual entropy variables

One-dimensional stationary energy-transport equations for semiconductors in the dual entropy variable formulation are numerically discretized employing a mixed-hybrid finiteelement method which has the advantage to fulfill current conservation. Numerical results for two ballistic diodes are presented and numerical convergence rates are computed.

Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Anisotropic adaptive finite element method for modelling blood flow.

In this study, we present an adaptive anisotropic finite element method (FEM) and demonstrate how computational efficiency can be increased when applying the method to the simulation of blood flow in the cardiovascular system. We use the SUPG formulation for the transient 3D incompressible Navier-Stokes equations which are discretised by linear finite elements for both the pressure and the velo...

Dual - Porosity Reservoir Model with an Improved Coupling Term

A new dual-porosity model is developed for singlephase flow in fractured/porous media. As in the commonly-used approach, flow is assumed to take place through the fracture network, and between the fractures and matrix blocks. The matrix blocks are treated in a lumped-parameter manner, with a single average pressure used for each matrix block. However, instead of assuming that fracture/matrix fl...
