Minicourses
  • This minicourse is for those who are just starting out with COMSOL Multiphysics® or want a refresher on the graphical user interface (GUI) and modeling workflow. During this session, the fundamentals of using the COMSOL® software will be demonstrated.


  • In this minicourse, you will learn about modeling conductive and convective heat transfer with COMSOL Multiphysics®, the Heat Transfer Module, the CFD Module, and the Subsurface Flow Module. Conductive heat transfer modeling addresses heat transfer through solids and can include heat transfer in thin layers, contact thermal resistance, and phase change. Convective heat transfer addresses heat transfer in solids and fluids. We will also address natural convection induced by buoyancy forces.


  • Whether you choose to construct a geometry in the COMSOL Desktop® or import it from a CAD file, this minicourse will demonstrate some useful tools. Did you know that COMSOL Multiphysics® can automatically generate the cross section of a solid object and you can use it for a 2D simulation? Or that you can directly import topographic data to create 3D objects? Generating a geometry is also about preparing selections for physics settings. By using the right selection tools, you can easily automate the modeling workflow, even when this involves simulations on widely different versions of a geometry. Attend this minicourse to see a demonstration of these techniques and more.


  • In this minicourse, we will cover the Microfluidics Module, which features custom interfaces for the simulation of microfluidic devices and rarefied gas flows. Single-phase flow capabilities include both Newtonian and non-Newtonian flow. Beyond its single-phase flow capabilities, this module also allows for two-phase flow simulations to capture surface tension forces, capillary forces, and Marangoni effects. Typical applications include lab-on-a-chip (LOC) devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems.


  • In this minicourse, we will cover the use of the RF Module for simulating Maxwell's equations in the high-frequency electromagnetic wave regime. We will discuss applications in resonant cavity analysis, antenna modeling, transmission lines and waveguides, and scattering. Then, we will address the coupling of electromagnetic wave simulations to heat transfer, such as in RF heating.


  • Many different physical phenomena are coupled to the deformation of solids. In this minicourse, you will get an overview of how to model fluid-structure interaction, thermal stresses and thermoelastic damping, electromechanical forces, magnetostriction, piezoelectricity, poroelasticity, and acoustic-structure interaction. The built-in multiphysics couplings are highlighted, together with examples of how to create your own couplings.

  • Drying of Soft Cellular Foods: Multiscale and Conjugate Modeling Perspectives

    In this talk, I will share our latest modeling research on convective drying processes for soft cellular materials, such as fruits. I will show how multiscale modeling from the cellular scale up to the dryer scale can increase our understanding of what changes inside these exciting materials during drying. Furthermore, I will illustrate the importance and impact of a conjugate coupling of the moisture transport in the porous material to that in the turbulent airflow around it. Finally, I will discuss how we use modeling to optimize convective dehydration processes, such as solar and electrohydrodynamic drying.


16:30
Minicourses, Workshops, and Panel Discussions
  • In this minicourse, we will walk you through the meshing techniques that are available to you in the COMSOL Multiphysics® software. We will introduce you to basic meshing concepts, such as how to tweak the meshing parameters for unstructured meshes. More advanced topics include working with swept meshes and creating mesh plots. You will also learn a useful technique for meshing imported CAD designs: How to hide small geometry features from the mesher.


  • Radiative heat transfer is one of the three types of heat transfer and plays a major role in many applications. During this session, we will focus on the features for modeling surface-to-surface radiation for gray surfaces or multiple spectral bands, such as solar and infrared radiation. We will discuss different examples in order to help identify cases where thermal radiation has to be accounted for.

    Defining ambient conditions is a key point in the model definition, especially when solar radiation is accounted for, but there are also other cases. We will review the different means to define the ambient condition and how use them for conduction, convection, and radiation in heat transfer models.


  • Learn how to efficiently simulate incompressible and compressible turbulent flows in this CFD minicourse. The CFD Module allows for accurate multiphysics flow simulations, such as conjugate heat transfer with nonisothermal flow and fluid-structure interactions. We will also discuss physics interfaces for simulating flow in porous media, discrete and homogeneous two-phase flow, and flow in stirred vessels with rotating parts.


  • COMSOL Multiphysics® gives you precise control over the way in which your multiphysics models are solved. In this minicourse, we will cover the fundamental numerical techniques and underlying algorithms used for steady-state models and explain the reasons behind the default solver settings. Building upon this knowledge, you will learn various techniques for achieving or accelerating convergence of nonlinear multiphysics models.


  • The Wave Optics Module offers both full-wave modeling of Maxwell's equations and the beam envelope method. The beam envelope method is particularly useful for modeling optical waveguiding structures, where the field envelope varies slowly along the direction of propagation. This minicourse introduces the use of the beam envelope method and how it contrasts with full-wave models. Optical scattering from periodic structures, such as gratings, will also be covered.


  • Virtual prototypes and digital twins play a major role in the development process across industries. This is also true when dealing with acoustics, from designing audio systems in cars and optimizing miniature transducer performance in mobile devices to designing muffler systems. Common to these applications is the need to use different modeling strategies depending on the frequency range, model size, and details included in the physics used. The integration of simulations and testing is also important.
