Minicourses
  • In this minicourse, you will learn about modeling conductive and convective heat transfer with phase change using the COMSOL Multiphysics® software, Heat Transfer Module, CFD Module, and 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 show you how to model natural convection induced by buoyancy forces. Additionally, changes in the temperature of a material can lead to a change in material phase, from solid to liquid to gas. This minicourse will introduce you to the various types of phase change modeling that can be done with COMSOL Multiphysics®. We will also discuss how lumped thermal equivalent circuit components can be used for heat transfer analysis, and how they can be coupled to the heat transfer FE models.


  • Get an overview of the general functionality for laminar flow in the CFD Module, followed by a detailed description of the functionality added with the Microfluidics Module. The Microfluidics Module features custom interfaces for the simulation of microfluidic devices. Single-phase flow capabilities include both Newtonian and non-Newtonian flow. Beyond the single-phase flow capabilities, the Microfluidics 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, you will learn different approaches for modeling layered shells in COMSOL Multiphysics®. The Layered Shell interface will be covered in detail, including the modeling of delamination. You will also learn how to extract homogenized material properties from a micromechanical model using a representative volume element approach. Finally, the analysis of multiphysics problems in layered shells will be discussed.


  • The high-fidelity simulation of optical systems in particularly harsh environments must account for the impact of thermal and structural effects on optical performance. For example, the large temperature changes found in outer space and high-powered laser focusing systems can change the refractive indices due to thermo-optic dispersion. Under extreme conditions, the elements of the optical system may experience significant thermal stress, causing physical deformation and a further degradation of the image quality.

    In this minicourse, you will learn how to use the Ray Optics Module to perform coupled structural-thermal-optical performance (STOP) analyses of optical systems. You will learn how to use COMSOL Multiphysics® to compute temperature and displacement fields using the finite element method (FEM) and then couple these fields to a ray optics simulation using built-in optical dispersion models. The distinction between unidirectional and bidirectional couplings in STOP analysis models will also be explained.


  • In this minicourse, you will learn how to model problems within the field of structural mechanics. You will learn about the modeling of stresses, strains, and deflections in solid materials and mechanisms. Stationary, transient, and frequency-domain analysis; eigenfrequency analysis; and modal superposition will be covered. Shells, membranes, beams, and trusses will also be introduced. Damping models, nonlinearities, linearization, and prestressed analysis are other important topics.


  • In this minicourse, you will learn how to define chemical kinetics, thermodynamic properties, and transport properties for models of reacting systems using the Chemical Reaction Engineering Module. We will address topics including homogeneous and surface reactions, diffusion and convection in diluted and concentrated solutions, thermal effects on transport and reactions, and mass and heat transfer in heterogeneous catalysis.

You will also learn how to use the Method Editor and other tools to efficiently write methods to extend the functionality of your apps.


  • Importing CAD designs often involves modifying the geometry after the import; for example, to remove unwanted details, create additional computational domains, or even restore missing faces. Besides demonstrating the tools for these tasks, this minicourse will also cover best practices for working with imported CAD geometries and how to interface CAD software using the LiveLink™ interface for an efficient optimization of CAD designs.


  • Attend this minicourse to learn about the tools for generating geometry with COMSOL Multiphysics®. We will cover how to efficiently build geometry that can be parameterized and look into more advanced techniques; for example, how to create a geometry from simulation results.

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.


  • In this minicourse, we will cover the use of the RF Module and Wave Optics Module for simulating Maxwell's equations in the high-frequency electromagnetic wave regime.

  • 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.


  • In this minicourse, you will learn how to define and solve problems in electrodeposition, corrosion protection, and corrosion studies. These systems all involve mass and charge transfer coupled to electrochemical reactions at deforming metal surfaces. We will look at two different approaches: one that treats the surface deformation as a variable and a second approach that treats the surface deformation with moving mesh. The most common type of study for these systems is the time-dependent study, but we will also briefly look at electrochemical impedance spectroscopy (EIS) studies.


  • In this minicourse, we will study different classes of problems involving acoustic propagation in fluids and solids, ranging from propagation in large domains, such as rooms or the ocean, to transmission through small perforations, where thermal and viscous losses are important. We also discuss modeling the interaction of elastic waves in solids and pressure waves in fluids (ASI) as well as propagation in moving fluids; that is, convected acoustics or aeroacoustics. You will also learn about recent news and additions to the COMSOL Multiphysics® software relevant to acoustics. Application areas include, but are not limited to, muffler design, sound insulation materials, room and car acoustics, flow meters, and liners.


  • Magnetic fields arise due to magnets and the flow of current.

In this minicourse, we will address the modeling techniques that you should be aware of and then go into the choice of solvers for large models. We will cover the differences between the various solvers in the COMSOL Multiphysics® software in terms of their time and memory usage. Additionally, solver performance is inextricably linked to computer architecture. This course will discuss how factors such as memory bandwidth, processor speed, and architecture affect solution times.

Building upon this knowledge, you will learn various techniques for achieving or accelerating convergence of nonlinear multiphysics models. You will also learn how to pick a solver based on the problem at hand, measure and control computational error, as well as check convergence and other salient issues in time-dependent analyses using the finite element method.


  • Shape optimization involves the free-form deformation of your CAD part via the Deformed Geometry interface. It is possible to set up such a deformation with respect to just a few control variables, and use these variables within the gradient-based optimization capabilities of the Optimization Module to quickly come up with improved designs. Often, setting up such a deformation can be quite challenging. Come learn how to efficiently set up and solve such models.
