Porous materials can be found in numerous areas of life (e. g., applied science, material science), however, the simulation fluid flow and transport phenomena through porous media is a significant challenge nowadays. Numerical simulations help to analyze understand physical processes different structure, as well determine certain parameters that are difficult or impossible measure directly only...

Cautery is a process to coagulate tissues and seal blood vessels using heat. In this study, finite element modeling (FEM) was performed to analyze temperature distribution in biological tissue subject to a bipolar electrosurgical technique. FEM can provide detailed insight into the tissue heat transfer to reduce the collateral thermal damage and improve the safety of cautery surgical procedures...

Primljeno (Received): 2011-10-10 Prihvaćeno (Accepted): 2011-12-20 Original scientific paper Virtual reality (VR), as a novel technology, represents one of the most powerful tools to assist or even play the major role in many areas, such as development of new designs, training medical practitioners or assembly operators, entertaining industry, etc. On the other hand, the finite element method (...

We consider the scattering of monochromatic electromagnetic waves at a dielectric object with a non-smooth surface. This paper studies the discretization of this problem by means of coupling finite element methods (FEM) and boundary element methods (BEM). Straightforward symmetric coupling as in [R. Hiptmair, Coupling of finite elements and boundary elements in electromagnetic scattering, SIAM ...

In this study the dynamic of a six petals reed valves pack is simulated accounting the complex fluid interaction phenomena occurring during transient flow of a typical working cycle of a two-stroke engines for go-kart competition. Starting from previous works on FSI (Fluid Structure Interaction) simulation for 2D cases and after the optimization of valve material considering only the structural...
