Organogenesis is a highly dynamic process that is tightly regulated during embryogenesis. Many of the individual regulatory components, such as signaling molecules and their receptors, as well as their regulatory interactions have been identified in experiments. However, an integrative mechanistic understanding of the regulatory network is missing [1]. In a series of papers on simulating organo...

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The results obtained from mixed-level model simulation performed in COMSOL Multiphysics agree very well with experiment...

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

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the performance of a range of MEMS devices by decreasing any unwanted coupling effects or parasitic losses from the dev...

Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior in the glass transition regime. COMSOL Multiphysics software 4.3b can simulate the stress relaxation with the WLF (WilliamsLandel-Ferry) shift function, but no structural relaxation. In this study we developed a framew...

Many physical applications require the solution of a system of coupled partial differential equations (PDEs). In most cases the analytic PDE solution does not exist for this system and we need to solve the problem numerically using the finite element method in COMSOL. This paper presents information on techniques needed in COMSOL 4 to enable computational studies of coupled systems of PDEs for ...

While Comsol Multiphysics has great flexibility for modeling photonic devices, the computational demands of the general finite element method make it most suitable for small devices, on the order of a few microns in extent. Many integrated optical devices are much larger, having lengths of hundreds of microns or millimeters. A beam propagation method (BPM), which applies some simplifying assump...
