Modeling of migrating cells often requires sophisticated numerical tools necessary for solving highly nonlinear partial and ordinary differential equations in domains with moving boundaries. We have recently developed a novel conservative method [1] for simulating reactions and transport in moving domains, which combines an Eulerian approach with tracking an explicit boundary. The latter is imp...

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient's own cells inside scaffolds. TE scaffolds are porous constructs that act as a support structure during bone regeneration and helps cells attach and pr...

We present a Finite Element Method simulation procedure that allows rapid development of prototype devices comprising novel self-referenced interference SPR (surface plasmon resonance) biosensing microstructures. The procedure takes advantage of commercial Comsol Multiphysics and Matlab software and their bi-directional link.

In this paper, we have design MEMS module based on thermal expansion using COMSOL Multiphysics. This device thermally expands when it is subjected to temperature. Beryllium copper alloy is used as material for this device. The expansion is measured in-terms of displacement.

A MEMS thermal actuator is a micromechanical device that typically generates motion by thermal expansion. In this paper we have studied the thermal expansion of different shapes of thermal actuator and implemented using COMSOL tool.Different shapes are designed and analyzed.Rectangular, triangular and U shaped actuator is designed and implemented.

In this paper, the implementation of open-source parallel-version FDTD (Finite-Difference-Time-Domain) software, MEEP, on Texas A&M supercomputers and commercial finite element package, COMSOL, on a single workstation for the design design of nano-optical device is reported. The the computer architecture and performance of both numerical methods on the same design will be briefly described.

This paper presents the simulation of the dual electromagnet Active Magnetic Levitation System realized in the COMSOL Multiphysics software. The mixed mode of Partial Differential and Ordinary Differential Equations is used to realize the levitated object motion. Two control scenarios are given as illustrative example of the working model.

The impact of the electromagnetic waves (EM) on human neurons (HN) has been under investigation for decades, in efforts to understand the impact of cell phones (radiation) on human health, or radiation absorption by HN for medical diagnosis and treatment. Research issues including the wave frequency, power intensity, reflections and scattering, and penetration depths are of important considerat...

This theoretical study describes the optical multilayer structure models leading to investigate Surface Plasmon Polariton (SPP) to an extern applied magnetic field at visible wavelenght using a 3D-FEM based on Comsol Multiphysics software. The layered structures include the amorphous silicon c-Si octahedral nanocrystals on the interface SiO2/dielectric were investigated to enhance the SPP inten...
