In COMSOL Multiphysics it is possible to implement and simulate several independent models in parallel. This can be meaningful when the different models are coupled to each other by some kind of interaction. If a part of the geometries is identical in all models, this part can be reduced in that it is implemented in only one of the geometries. In the other geometries only its solution towards ...

In this paper, we will present simulation results obtained using COMSOL RF module for the current along a wire antenna in both frequency and time domains. The structure is excited through a lumped (voltage or current) source at its center. For the frequency domain simulations we compare the results with the Numerical Electromagnetics Code (NEC-4) and for the time domain results we compare them ...

Neural disorders like epilepsy, Parkinson’s disease and Alzheimer’s disease have become a major area of concern because of their complexity and the huge number of occurrences. At present, most of the treatments are based on drugs and external nerve stimulation demanding critical care. This study aims at the design and simulation of an implantable micro-electrode which can lead to better ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The ...

When milk is taken out of a refrigerator it has to be heated up to 37°C. The standard solution is to put the bottle in a bath of warm water and wait. The goal is quickly to achive a uniform temperature of 37°C, without ever exceeding 40°C. Using COMSOL Multiphysics and a measurement setup for calibration, we show that this can be improfed by using variable heating. By choosing heating ...

Conductive Composites such as carbon fiber reinforced composites are increasingly used in safety critical aerospace applications. The catastrophic macro structural failure of composite structures initiates from a micro level failure event such as fiber breaks. The ability to detect damage early on can improve the safety level and reliability of composite structures. A multilevel self-sensing ...

Results presented are a contribution to the design of a 5kW-DC-AC-converter for applications in forklifts. The device is located in a closed environment and entirely operated with passive cooling. Due to concurrent engineering approach and environmental conditions correct prediction of absolute temperature values by simulation was crucial. Heat sinks have been modeled properly and a thermal ...
