Estimation of Boundary Properties Using Stochastic Differential Equations and COMSOL
The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, ... Read More
Linear LS Parameter Estimation of Nonlinear Distribute Finite Element Models
This work concerns the development of a new direct parameter identification procedure for a class of nonlinear reaction- diffusion equations. We assume to know the model equations with the exception of a set of constant parameters, such as diffusivity or reaction term parameters. Using ... Read More
Multi-Objective Optimization of a Ball Grid Array Using modeFRONTIER® and COMSOL Multiphysics®
Capacitive MEMS (Micro-Electro-Mechanical Systems) accelerometers may be directly soldered to the printed circuit board by an array of solder balls. Differences in the thermal expansion coefficients of the pertinent materials cause deformations of the accelerometer under temperature ... Read More
Integrating COMSOL into a Mathematical Modeling Course for Chemical Engineers
The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... Read More
Stability Analysis of ALE-Methods for Advection-Diffusion Problems
ALE-methods are frequently used to solve systems of partial differential equations (PDEs) on moving domains. The main idea of these methods is to incorporate the time evolution of the domain into the equations. However, the motion of the domain with respect to time induces convective ... Read More
Numerical Demonstration of Finite Element Convergence for Lagrange Elements in COMSOL Multiphysics
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 ... Read More
COMSOL Multiphysics Models for Teaching Chemical Engineering Fundamentals: Absorption Column Models and Illustration of the Two-Film Theory of Mass Transfer
COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO2 and SO2 from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent to ... Read More
Resonating with Students in the Undergraduate Physics Laboratory: Comprehending Acoustic Vibrations
Acoustic vibrations are studied for several objects through the application of computational and optical diagnostic techniques. Computational studies are carried out using the eigenfrequency analysis option in the COMSOL structural mechanics application mode, whereas experimental optical ... Read More
Modeling Dispersal of Genetic Information in Structured Agricultural Landscapes with Partial Differential Equations
We present a model for plant dispersal in agricultural landscapes to evaluate the gene dispersal from genetically modified (GM) plants. Dispersal from seed and pollen is modeled with partial differential equations. In scenarios, we investigated the effect of roadside application of non ... Read More
Parameter Identification in Partial Integro-Differential Equations for Physiologically Structured Populations
Continuous dynamic models, e.g. COMSOL based simulations, play – besides statistical or iterative methods – a mayor role in theoretical ecology; in forecasting and management, but also in systems analysis. Ecological issues generally comprise highly interacting agents and/or unknown side ... Read More
