Keynote presentation.- Creating and Running Multiphysics Apps

Minicourse.- Application Builder and COMSOL Server

Abstract

The Application Builder allows users of COMSOL Multiphysics® to create their own graphical user interfaces (GUI), for specific purposes, to control an embedded multiphysics model. These tailored user interfaces, including the embedded model, are called applications or “apps”. The purpose of creating these apps is to make it possible for engineers and scientists, that are not modeling experts, to benefit from multiphysics modeling and simulations for their specific needs. As a COMSOL Multiphysics user, you may develop apps for students, friends, colleagues, partners, and customers. You can also charge your customers for the apps.

COMSOL Server is able to host the server processes that drive the apps with the user interface run on a local client, for example an html-client or a desktop client. The combination of the Application Builder and COMSOL Server™ makes it very straight forward for modeling experts to develop and share their apps.

This presentation and minicourse demonstrate the use of the Application Builder for developing apps. It shows how you can graphically design user interfaces by dragging and dropping graphic forms and widgets such as menus, input fields, buttons, checkboxes, plot figures, etc. Also the linking of graphics widgets to commands that control the embedded model is demonstrated: for example to control model parameters, mesh, solvers, and results. A demo of the use of COMSOL Server to administrate and run apps gives you a glimpse of the possibilities with this new functionality.

Ph.D. in Applied Mathematics at the University of Montpellier (France). His main research themes are about optimisation methods and their applications to industrial problems. In particular, he has extensively used COMSOL Multiphysics to model and solve design problems, such as improvement of microfluidic mixers, study of the effect of Pressure/Temperature in food treatment devices or conception of Pulsed Electric Field chambers.

Minicourse.- Solving industrial design problems by using COMSOL Multiphysics with MATLAB

Abstract

COMSOL Multiphysics is a very efficient tool for modeling numerically complex devices. In particular, this software can be used during the industrial design processes involving optimization problems.One interesting characteristic of COMSOL Multiphysics is the possibility of incorporating the created model into a MATLAB script code. This allows the MATLAB script to automatically change some considered model parameters, such as geometrical shapes, physical characteristics, etc. Thus, any optimization algorithm compatible with MATLAB script can solve an optimization problem involving a COMSOL Multiphysics model. During this minicourse, first we will detail the basic steps to create and solve industrial design problems by coupling COMSOL Multiphysics with MATLAB. Then, we will illustrate the presented methodology by considering the optimization of a fast hydrodynamic focusing microfluidic mixer for protein folding.

Keynote presentation.- Electromagnetic Field Simulation in Microwave Ovens: from code to COMSOL Multiphysics

Abstract

In a short sentence, designing a microwave oven involves mastering methods that allow the best energy transfer, the maximum energy containment and an optimal load thermal energy distribution. From an experimental point of view these three components have to be dealt with an equal importance in order to achieve the best equilibrium possible. Spite the reliability of such methods they have the drawback of being time consuming, any variant in design requires a full set of analysis to be validated. Computer simulations, using the FTDT method coded in FORTRAN, were first used to compare results of simulated radiation leakage of several designs of a microwave oven´s doors against experimental measurements. Simulation and experimental data matched perfectly, and with this the confidence in simulation methods increased. COMSOL Multiphysics was first used in GREENWAVE, a project intended to create industrial hybrid microwave/gas ovens, to simulate the electromagnetic field distribution inside and subsequent heating pattern on ceramic composites. This originated three prototypes with microwave output powers ranging from 6 kW to 20kW. In the following project, CURECORK, a small prototype of 2kW was created to evaluate the feasibility of microwave energy in the thermal curing process of cork agglomerates under higher pressures. In 2014 Teka Portugal S.A. acquired a COMSOL Multiphysics license to begin simulations on EM fields in microwave ovens, load’s heating pattern and leakage through the oven´s door. Although this research is at an early beginning, the primary results rouse an interest in the use of COMSOL Multiphysics in CFDs, intended to simulate oven’s cooling systems and, more important, cooker hoods air flow pattern in order to achieve better products in terms of fluid dynamic efficiency.

Ana María CarpioAna María Carpio Rodríguez.
Complutense University of Madrid, Spain.

Professor of Applied Mathematics in the Universidad Complutense de Madrid. She received her Ph.D. degree from the Laboratoire d’Analyse Numérique (now Jacques Louis Lions, Université Paris VI, 1993) and conducted her postdoctoral research in the Oxford Centre for Industrial and Applied Mathematics (University of Oxford, 1996–1997).
Her research interests span upon a wide variety of problems, ranging from applied topics, such as multiscale modeling of bio- and nano-systems, imaging, or the study of defects in graphene, to theoretical and numerical analyses of differential equations. Her recent work on the formation and spread of biofilms in medical and industrial flow systems has made extensive use of COMSOL Multiphysics.

Keynote presentation.- Geometry induced biofilm formation

Abstract

Bacteria in aqueous environments usually gather to form aggregates called biofilms. In biofilms, cells display many behavioural differences from planktonic cells, such as a 1,000-fold increase in tolerance to antibiotics. Hospital-acquired infections are often caused by biofilm spread through medical systems. Design improvements hindering biofilm formation rely on identifying factors that favour their appearance. We will see that the presence of corners and narrowings in medical flow circuits triggers biofilm nucleation by creating secondary vortical motion driving bacteria to walls. Detailed flow studies in micro- and mili-fluidic devices support that observation. Once biofilm seeds are created, they proliferate forming filaments whose structure is again controlled by the geometry. In this work, COMSOL Multiphysics has been extensively used to identify flow structures induced by the geometry that affect the biofilm formation process.
