Transient Pseudo-3D Model of Multi-Beam Laser Thermal Treatment System
Laser thermal treatment (LTT) systems have applications in IC fabrication for improving low-k dielectrics properties, polymer curing and resist processing. This contribution deals with a transient model of fast scanning and pulsing laser multi-beam system used in semiconductor ... Read More
Coupled Magnetodynamic and Electric Circuit Models for Superconducting Fault Current Limiter
Finite element models, which include the shielding characteristics of superconductors are often complex and would currently not allow us to study 3D models of devices of complex geometry such as fault current limiters. We propose instead a model based on variable electric conductivity, ... Read More
Hybrid FEM-BEM Approach for Two- and Three-Dimensional Open Boundary Magnetostatic Problems
In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not ... Read More
Investigations on Hydrodynamic in Stirred Vessels for Educational Purposes
With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research ... Read More
COMSOL API Based Toolbox for the Mixed-Level Modeling of Squeeze-Film Damping in MEMS: Simulation and Experimental Validation
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 ... Read More
Benchmark of COMSOL vs. ROXIE Codes for the Calculation of a Particle Accelerator Quadrupole
The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting ... Read More

Sequential Simulation in COMSOL using Differential Equations to Perform Digital Switching
Many physical systems contain sequential modes of operation. The sequence is one-way and switching between modes is dependent upon specific internal parameters of the system itself. While COMSOL provides the flexibility to perform time-domain simulation and time-based modifications of ... Read More
Double Pipe Heat Exchanger Modelling - COMSOL Uses in Undergraduate Education
A cornerstone of Chemical and Mechanical Engineering undergraduate programs the world over is the experimental and theoretical study of heat exchange. Graduating engineering students gain some appreciation in their lab course by comparing empirical correlations combined with the ... Read More
