This paper presents the implementation of eXtended Finite Element Method (XFEM) in general-purpose commercial software COMSOL Multiphysics for first time. An enrichment strategy is proposed, consistent with structure software. To this end, each set functions, an additional Solid Mechanics module incorporated into numerical framework, coupled compatible modifications to internal variables. The L...

--MEMS based mass sensors are being designed to identify the small amounts of materials especially for monitoring the food supply. The Fabrication of MEMS includes deposition of material layers, pattering by photolithography and etching to produce the required shapes, consequently leading to time taking and expensive method. In order to reduce the working time of sensor to market a Finite eleme...

In this study, the flow channels of a PEM fuel cell are fabricated by the EMM process. The parametric effects of the process are studied by both numerical simulation and experimental tests. For the numerical simulation, the multiphysics model, consisting of electrical field, convection, and diffusion phenomena is applied using COMSOL software. COMSOL software is used to predict the parametric e...

1 Graduate student 2 Professor ABSTRACT Ac electrokinetic flows are commonly used for manipulating micron-scale particles in a biosensor system. At the solid-liquid state there are two kinds of processes in the reaction between analytes and ligands: the mass transport process and the chemical reaction process. The mass transport process is related to convection and diffusion. Total or partial l...

Organogenesis is a tightly regulated process that has been studied experimentally for decades. Computational models can help to integrate available knowledge and to better understand the underlying regulatory logic. We are currently studying mechanistic models for the development of limbs, lungs, kidneys, and bone. We have tested a number of alternative methods to solve our spatiotemporal diffe...

Mathematical Modelling has a long history in developmental biology. Advances in experimental techniques and computational algorithms now permit the development of increasingly more realistic models of organogenesis. In particular, 3D geometries of developing organs have recently become available. In this paper, we show how to use image-based data for simulations of organogenesis in COMSOL Multi...

In this paper, we have addressed the Design and simulation results of an electrostatically controlled micro mirror using COMSOL multiphysics Software. The structural mechanical properties of the actuation mechanism of a square shape micro-mirror with the lift-off of the structure used four springs simulating a prestressed cantilever beam. There are few base materials were introduced like Alumin...

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 poor approximation of curved boundaries by polygonal meshes and lack of regularity of the PDE solution. We show studies for Lagran...

Induction heating is clean environmental heating process due to a non-contact heating process. There is lots of the induction heating type that be used in the home appliance but it is still new technology in Indonesia. The main interesting area of the induction heating design is the efficiency of the usage of energy and choice of the plate material. COMSOL Multiphysics Software can be used to s...

Steam-Assistant-Gravity-Drainage (SAGD) has become one of the most commonly used thermal recovery processes to extract heavy oil from oil sand reservoirs, especially in Northern Alberta, Canada. However, due to geological history, interbedded shales (IBS) in the reservoir act as barriers due to their low permeability and as such hinder the progression of the steam chamber. Cap-rock integrity al...
