A new computational approach for simulating bone adaptation was implemented using FEMLAB with MATLAB and Simulink. A Simulink model was created to describe shape adaptation of bone as a negative feedback system, in which the adaptation driving signals tend to return to an equilibrium range in which no shape adaptation will occur. FEMLAB was invoked using a MATLAB S-function in the Simulink ...

Numerical simulations of electrochemical impedance diagrams are reported using a 2D-axis symmetry FEM calculations. The impedance is the ratio of the potential over the current, but it is highly depending of the concentration of the various chemical species in the solution, particularly the ionic ones wich are sensible to migration, diffusion and convection effects. In this study, only the ...

COMSOL (formerly FEMLAB) is being utilized to solve partial differential equations simulating fluidized bed reactors as part of the development of a novel generalized fluidized-bed catalytic reactor model. Simulations are carried out to account for complex dynamic transport and hydrodynamic phenomena such as: heat and mass axial and radial anisotropic dispersion, temperature and pressure ...

The cold crucible is a tool which is frequently used for induction heating applications for the elaboration of materials by middle or high frequency magnetic field. This crucible is made of copper sectors assembled together to form the container in which the electroconductive material is molten. Each sector is water cooled, which keeps the crucible cold when the material is heated and molten ...

The design of micro and nanoscale systems is a great challenge for modelling and simulation. In particular Lab-on-a-Chip-technology offers a wide spectrum of possible applications. Recently Bonaccurso and Butt (Bonaccurso & Butt 2005) presented a new approach to investigate droplet evaporation: They placed water droplets on rectangular, silicon atomic force microscope (AFM) cantilevers so that ...

Localized heating is poised to become an integral part of microfluidic devices in various life-science applications. This is catalyzed by the scale of economics, the advantageous fluidic behavior at small volumes, and the ever increasing need for rapid and high throughput assays for pharmaceutical industry and other combinatorialbased studies. For precision confined heating, thin film resistive ...

We used FEMLAB (Finite Element Modelling LABoratory) for modelling heat propagation in 4 dimensions (time and the 3 spatial dimensions) after pulsed laser heating of non-isotropic materials during surface science experiments. As an example, the spatial and temporal evolution of a laser induced temperature jump in highly oriented pyrolytically grown graphite (HOPG) was calculated on a ns time ...

Today, geophysical exploration can provide information on the interior of volcanoes even before the edifice is mechanically destroyed by measuring physical fields at the surface and interpreting them with the help of sophisticated modeling techniques. An especially interesting method to map and monitor active volcanic zones is the observation of electromagnetic fields. Electrical voltages can ...

The fluidic motion driven by Coulomb forces on charge clouds in the vicinity of charged walls immersed into an electrolyte is termed electroosmotic flow (EOF). Since the generated EOF pressure increases with decreasing hydrodynamic diameter, such actuation mechanisms are ideally suited for microfluidic applications and are widely discussed in the literature (see e.g. Li 2004). In addition to ...

Geomechanics is valuable to account the rock deformations due to pore pressure and temperature changes resulting from production and fluid injection. We have used the FEMLAB 3.1 earth science module’s coupled geomechanical-fluid flow model to test its application to near wellbore pressure transient analysis. The new feature in FEMLAB 3.1 enables to couple geomechanical and fluid flow models ...
