LiveLink™ for MATLAB®
LiveLink™ for MATLAB®
Per potenziare le simulazioni multifisiche con la flessibilità degli script
Le matrici del modello COMSOL sono state esportate nel workspace di MATLAB dove viene calcolata la soluzione.
Integrare COMSOL Multiphysics® con il linguaggio script di MATLAB®
E' possibile integrare le analisi effettuate in COMSOL Multiphysics® con MATLAB® e viceversa per estendere la modellazione con la programmazione degli script in ambiente MATLAB. Il LiveLink™ for MATLAB® consente di sfruttare tutta la potenza e i toolbox di MATLAB per il pre-processing, la manipolazione del modello e il post-processing; esempi di applicazioni includono:
- Migliorare il codice MATLAB sviluppato internamente con le soluzioni di problemi multifisici offerte da COMSOL
- Fondare la modellazione geometrica su dati probabilistici o estratti da immagini
- Eseguire un'analisi statistica sui risultati delle simulazioni * Utilizzare modelli multifisici insieme a simulazioni Monte Carlo e algoritmi genetici
- Esportare le matrici rappresentative dei modelli COMSOL in MATLAB state-space per incorporarle in sistemi di controllo
- Chiamare funzioni MATLAB da COMSOL Desktop®

Analysis of Subsea Umbilicals and Cables
Tim Poole, JDR Cables, Cambridgeshire, UK and Mark Yeoman, Continuum Blue, Hengoed, UK
JDR Cables designs-to-spec and manufactures subsea umbilical systems of cables and reelers for the oil and gas and renewable energy industries. In these designs, the harsh environments of deep water pressure, wind and waves, as well as the rough ocean floor must all be considered, along with the forces acting on cables from being pulled and ...
How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet
O. Craciun, and colleagues ABB AG Ladenburgh, Germany
When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process ...
Nanoresonators Get New Tools for Their Characterization
J. Yang, M. Perrin, P. Lalanne CNRS, France
Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not ...
Sonar Dome Vibration Analysis
Francesca Magionesi INSEAN Italy
There has been a recent move towards utilizing bulbous bows on ships to house different types of sonar systems, but it is not definite how much structural vibration might interfere with the functioning of a transducer array inside the sonar dome. INSEAN, the National Institute for Studies and Experiments of Naval Architecture in Italy, needed a ...
Highly Accurate Li-ion Battery Simulation
Mikael Cugnet French Atomic and Alternative Energy Commission
Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do ...
Reduced-Weight Reaction Sphere Makes Way for Extra Satellite Payload
Leopoldo Rossini, Emmanuel Onillon, & Olivier Chetelat CSEM SA, Neuchatel, Switzerland
CSEM is a private applied research and development center specializing in micro-technology, system engineering, micro-electronics, and communications technologies. One of their latest projects is working on minimizing the weight of satellite attitude control systems as every gram of payload matters when launching a satellite into orbit (€15,000 ...
Optimized Heating Process with Uniform Coating
Mika Judin Rautaruukki Oyj Hämeenlinna, Finland
Rautaruukki Oyj supplies metal-based components and systems to the construction and mechanical engineering industries, where process engineer, Mika Judin, works with optimizing their coating technologies. When coating rolled metal with paint, it is important that the coating be applied such that it is not discolored or damaged, and that it is ...
Homogenization in a Chemical Reactor
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time-dependent solver, then restart it with an initial value obtained ...
Parameterized Busbar Geometry
This is a template MPH-file containing the physics interfaces and the parameterized geometry for LiveLink™ for MATLAB® modeling example.
Domain Activation and Deactivation
Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®.
Convective Heat Transfer with Pseudo-Periodicity
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the outlet boundary from the previous solution is mapped to the ...
Temperature Distribution in a Vacuum Flask
This example solves for the temperature distribution inside a vacuum flask holding hot coffee. The main purpose is to illustrate how to use MATLAB functions to define material properties and boundary conditions.
