The consequences of hip fracture and femoral fracture are widely known. The mechanical strength of the femur varies in every person, but it is possible to predict the mechanical resistance with parameters like density, dimensions and mineral content. This paper uses different models and empirical studies to determine the mechanical properties of the human femur, developing isotropic and ...

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a Software. It is shown that the Fitzhugh-Nagumo equations allow for a geometrical explanation of important ...

The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled environment. In order to make this approach more accessible, it is necessary to reduce computation time as much as ...

Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has been used to assess the impact of the various purposed arrangements of fibers within the mat. Drug release ...

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design for on-chip cooling of microprocessors and SOCs. The EHD micropump works on the movement of microscale ...

A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell surface was computed via the Maxwell stress tensor. The 3D deformation of the cell was computed with the COMSOL ...

Organogenesis is a tightly regulated process that has been studied experimentally for decades. We are developing mechanistic models for the morphogenesis of limbs, lungs, and kidneys with a view to integrate available knowledge and to better understand the underlying regulatory logic. Organ size changes dramatically during development, and tissues are composed of several layers that may expand ...

In this paper, the gross electrical characterization of biological cells on porous substrate is analyzed using COMSOL Multiphysics®. Dynamic electrical characterization during cell growth is used as a non-invasive and label-free technique to understand the growth kinetics of cells. It is observed from the COMSOL simulation that the percentage change in the current density is greater in porous ...

In this paper, we present a first model carried out with COMSOL Multiphysics to model bread baking, considering heat and mass transfer coupled with the phenomenon of swelling. This model predicts the pressures, temperatures and water contents evolutions in the dough for different energy requests. First results obtained are analyzed according to various physical parameters in order to better ...

Cardiovascular disease has become a major healthcare problem. To tackle this along with bypass surgery, the use of the cardiovascular stent is considered promising and effective. In this study, we aim to find the effectiveness of stent deployments and their influence on haemodynamics post their deployment in human arteries. For the study we have reconstructed single units of two commercially ...
