We report an implementation of parallel computing on Amazon Web Services™ (AWS) for touch-sensor modeling. COMSOL Multiphysics® was used to simulate an electromagnetic field distribution in a capacitive sensor assembly. Multiple COMSOL jobs were deployed on separate AWS instances and were executed in parallel. The simulation results indicate that implementation of parallel computing for COMSOL ...

Aim of the study is to determine the influence of some of the most important operating variables, especially humidity and temperature, of drying air on the performance of cooking process of pork meat. The process is simulated using finite elements software COMSOL Multiphysics®. The proposed model considers two geometries: cylindrical and parallelepiped, with fixed physical properties and ...

Ammonia separation from water by membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside the hydrophobic hollow fibers, acid solution in the outside part. The system is in closed loop configuration. In order to simulate the separation process, equations were developed considering ...

Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood interacts with vessel wall mechanically and chemically which modulates the plaque formation in blood vessel leading to coronary artery diseases. Here we propose to simulate a MEMS based flexible flow sensor based on anemometer principle designed to ...

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 ...

Seawater intrusion into coastal aquifers is usually modeled by using transport models that include account for the effect of variable-density on flow. Variable-density models can be validated with the Henry and Elder benchmark problems. However, when mixed convective flow is simulated under variable density conditions, it is susceptible to physical and numerical instabilities. The purpose of this ...

In this study, a capability has been developed for modeling the linear viscoelastic behaviour of a glassy polymer using COMSOL Multiphysics®. The two rheological models by Maxwell and Kelvin-Voigt were used for modeling stress relaxation and creep loading behavior, respectively, of a typical gas pipe under two modes of plane stress and plane strain. An advantage of the developed model is its ...

The convergence order of finite elements is related to the polynomial order of the basis functions used on each element, with higher order polynomials yielding better convergence orders. However, two issues can prevent this convergence order from being achieved: the lack of regularity of the PDE solution and the poor approximation of curved boundaries by polygonal meshes. We show studies for ...

The determination of the modes of vibration of Functionally Graded-Metal-Ceramic Composite plates is important in practice in order to prevent undesired resonances in structural components. This paper describes the application of COMSOL Multiphysics® software for the determination of the modes of vibration of Aluminum A356-T6Alloy-ZrO2 FG-MCC square plates.

Borehole heat exchangers (BHE) in connection with heat pumps and floor heating in many countries are becoming an alternative to conventional heating or cooling systems using fossil resources. We describe how 1D components for heat transport in pipes can be coupled with a 2D or 3D component for the ground. Thermal conductances are derived for laminar, transitory and turbulent flow conditions in ...
