Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our previous papers on simulating organogenesis in COMSOL Multiphysics® we discussed methods to efficiently solve ...

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 ...

According to clinical reports, cardiovascular disease has become a major global healthcare problem. The deposition of fats, cholesterol etc. at the arterials walls causes thrombus formation leading to stenosis and arterial blockage. To tackle this, along with arterial bypass, the use of Cardiovascular Stent is considered promising and effective (in single vessel and bi vessel diseases). While ...

In this paper, a free membrane is used as a receiver to increase the capacitance and therefore the resolution of the flow meter. For the current application, from the wavelength of sound wave in soft tissue (c= 1540 m/s) the resolution was calculated to be 0.48 mm. This gives the first Eigen frequency of the capacitive structure according to which the poly silicon membrane was designed. After ...

We present a mechanical model a growing spherical shell suitable for predicting the evolution of a Saccular Cerebral Artery Aneurysms (SCAA). It relies basically on the Kröner-Lee decomposition, used to describe the interplay between the current and the relaxed configuration of body elements. Rupture or stabilization of a SCAA are the end effect of a number of biological mechanisms, still poorly ...

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human intestine, thereby advancing the diagnosis and treatment of gastrointestinal related diseases. The aim of this ...

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 structures able to overcome the present shortfalls of the metal and metal alloys implants related to ...

A simple steady-state photo-fermentative biochemical model was developed using the COMSOL Multiphysics'® Transport of Diluted Species physics interface. A dimensionless model seeks optimal physical parameters based on given biochemical parameters found in literature. A parametric sweep of the physical parameters is enabled without altering the mesh. Other limitations can be easily added to this ...

This paper utilizes the COMSOL Multiphysics® general form PDE interface and MATLAB® to model stochastic calcium waves in a sarcomere (basic unit of a heart cell). The model we present here shows the evolution of waves generated from calcium being released stochastically from sites modeled as point sources. The release sites are distributed on z-disc (planes) in a hexagonal pattern, and their ...

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an ...
