Image Based-Mesh Generation for Realistic Simulation of theTranscranial Current Stimulation
This paper will discuss the comprehensive solution adopted for converting the 3D digital/medical images directly into the computational model. The workflow using Simpleware Software – ScanIP and + ScanFE – will be illustrated including the option for directly exporting fully compatible ... En savoir plus
Solid Food Pasteurization by means of Ohmic Heating: Influence of Process Parameters
Pasteurization of solid food undergoing ohmic heating has been analyzed using COMSOL Multiphysics on the basis of a previously validated multiphysics model. The simulation of pasteurization by ohmic heating involves simultaneous solution electrical potential within the food, heat ... En savoir plus
Finite Element Analysis of Muscular Contractions from DC Pulses in the Liver
Thermal ablation of malignant tumors has been conducted in patients who are not candidates for surgery for more than ten years. Recently it has been shown that low energy DC pulses can cause cell necrosis. An undesirable characteristic of DC pulses in-vivo is the stimulation of skeletal ... En savoir plus
A Mean Field Approach to Many-particles Effects in Dielectrophoresis
One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in ... En savoir plus
Electrical Stimulation of Brain using a realistic 3D Human Head Model: Improvement of Spatial Focality
We calculated the spatial distribution of the electric fields induced in the brain during transcranial current stimulation (TCS). The spatial focality obtained using ‘concentric-ring’ configurations is investigated using a realistic MRI derived 3D finite element model of the human head. ... En savoir plus
Temperature Excursions at the Pulp-Dentin Junction during the Curing of Light-Activated Dental Restorations
Heat produced during the curing of light-activated dental restorations could damage the dental pulp. Given the prevalence of composite restorations and the importance of avoiding injury to the pulp, efforts should be made to minimize the temperature increase that occurs at the pulp ...

Image Based Mesh Generation for Realistic Simulation of the Transcranial Current Stimulation
Electrical stimulation of the brain involves the application of currents delivered through scalp electrodes to modulate brain activity, known as Transcranial Current Stimulation (TCS). A critical factor for TCS efficacy and safety is the “spatial focality” of induced neuronal modulation. ... En savoir plus
Using COMSOL Multiphysics for Modeling of Musculoskeletal Biomechanics
In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft ... En savoir plus
Analysis of 3D Biocompatible Additive Structure Using COMSOL Multiphysics® Software
For biocompatible prosthetics, from dental implants up to bone parts, manufacturers have to find the best way to correlate process parameters and the material properties as to meet the unique needs of individuals. Additive manufacturing techniques aim at creating complex biocompatible ... En savoir plus
On the Influence of Cancellous Bone Structure upon the Electric Field Distribution of Electrostimulative Implants
Since the 1980s, the accelerating effect of electromagnetic fields on bone regeneration is used to treat complicated fractures and bone diseases. At the University of Rostock, an electrostimulative hip revision system is developed, basing on the method of Kraus-Lechner. This method ... En savoir plus
