- COMSOL Multiphysics® for New Users
This minicourse is for those who are just starting out with COMSOL Multiphysics® or want a refresher on the user interface (UI) and modeling workflow. During this session, the fundamentals of using the COMSOL® software will be demonstrated.
- Overview of Chemical Reaction Modeling for New Users
Learn how to model chemical kinetics and reaction engineering capabilities, including batch/CSTR/plug flow reactors, CHEMKIN® file import, and the import of thermodynamic data. We will also discuss chemical species transport through diffusion, convection, and migration in electric fields, as well as reacting flow that involves fluid flow, heat transfer, and mass transfer with reactions. We conclude the course by reviewing and exemplifying the functionality for heterogeneous catalysis and packed bed reactors. We show how to model transport and reactions at the microscopic porous particle scale simultaneously with macroscopic transport at the bed scale.
- Tech Café: Heat Transfer
- Using the Mesher
In this minicourse, we will walk you through the mesh generation 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 and how to create structured meshes and meshes tailored for specific physics, such as fluid flow. You will also learn how to visualize the important properties of a mesh.
- Overview of Fluid Flow and Conjugate Heat Transfer for New Users
In this introductory course, you will get an overview of the general functionality for laminar and turbulent flow involving heat transfer. Conjugate heat transfer is automatically accounted for when using one of the predefined Nonisothermal Flow or Conjugate Heat Transfer multiphysics couplings. We will explore the various compressibility settings and learn to what extent thermal variations in the flow field are taken into account for the different options. In turbulent nonisothermal flow, we also have to consider turbulent Prandtl number effects, wall treatment, and buoyancy-induced turbulence.
- Tech Café: Geometry & Preprocessing
- Using the Geometry Tools
Attend this minicourse to learn about the tools for generating a geometry with COMSOL Multiphysics®. We will cover how to efficiently build geometry that can be parameterized and look into how to carry out tasks such as creating a sketch with dimensions and constraints, generating 2D cross sections of 3D objects, and more. Generating a geometry also involves preparing selections for physics settings. By using the right selection tools, you can easily automate the modeling workflow, even when it involves simulations on widely different versions of a geometry.
- Advanced Topics in Acoustics
In this minicourse, you will learn how to solve acoustically large models; that is, models that include many wavelengths. We will discuss what physics interface to select in the frequency domain and time domain, as well as best practices for meshing and the selection of the appropriate solver.
To model applications with high sound pressure levels or high particle velocities, it may be necessary to include nonlinear acoustic effects. You will get an introduction of when to select a specific model, the model applicability, and when nonlinear phenomena are of importance in general.
Finally, you will get an introduction to the various material models that are part of the Acoustics Module. This includes models for modeling porous materials, volumetric damping in fluids, as well as damping due to thermoviscous effects in microacoustic applications. We will touch upon the use of parameter estimation to determine some of the material parameters in these models that can be hard to determine.
- Tech Café: Fluids
- Panel Discussion: Simulation of Coils and Magnets
Coils and magnets are ubiquitous components in a wide array of electrical systems, from MEMS sensors to power transformers and everything in between. For the development of these devices, simulation plays an important role to help understand, predict, and optimize their performance. As system complexity increases, modeling tools need to provide capabilities for the handling of large geometries, interaction of different physics phenomena, and nonlinear material properties — while still producing robust and accurate simulation results.
Attend this panel to gain insight into advances in multiphysics modeling software and how it helps companies tackle today’s electromagnetics design challenges. Hear directly from our panel of experienced users of COMSOL Multiphysics® on how they apply the COMSOL® software to electrical device and coil design for their product development.

- Working with CAD Data
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 ensuring that physics settings do not need to be reapplied after a CAD file is reimported and how to interface CAD software using the LiveLink™ interface for an efficient optimization of CAD designs.
- Overview of Structural Mechanics Modeling for New Users
In this minicourse, you will learn about the basics of structural analysis. We will address static and dynamic analysis. In static analysis, you will first learn about linear analysis, when it is appropriate, and issues to watch out for. We will also focus on the fundamentals of how stresses and strains in a structure are computed. This will be followed by an understanding of the need for nonlinear analysis and issues to watch out for. Finally, we will learn about dynamic analysis, when it is appropriate, and issues to watch out for. In dynamic analysis, you will learn how to set up time-dependent and frequency domain simulations and focus on how to interpret complex-valued results from frequency domain analyses.
- Tech Café: Electromagnetics
- Developing and Deploying Applications
This minicourse will cover how to create simulation applications using the Application Builder, included in the COMSOL Multiphysics® software. A simulation application has a specialized user interface and it allows for nonspecialists in modeling to benefit from simulations. The minicourse will also give an overview of the different methods of deployment you can use to spread the use of simulation in your organization and to your customers. You will learn how to create standalone applications using COMSOL Compiler™ as well as how to make simulation applications accessible using COMSOL Server™.

These problems are typically extremely difficult for wave optics software. We will show how and why the COMSOL® software can solve these difficult problems. We will also show some advanced and practical application examples.
- Tech Café: Structural Mechanics
- Advanced Meshing Topics
This minicourse gives you further details of the meshing functionality in the COMSOL Multiphysics® software. You will learn a useful technique for meshing imported CAD designs by hiding small geometry features from the mesher. We will demonstrate the available tools for adapting meshes — that is, changing the size and distribution of elements, for example — according to error estimates in the solution. The minicourse will also explore the editing and repairing tools that are available for imported mesh data.
- Advanced Topics in Heat Transfer (Mostly Radiation)
In this minicourse, you will learn how to include surface-to-surface radiation in your models and how to make optimal use of the COMSOL® software's capabilities. In particular, learn how to define the radiation direction using the domains and layer opacity properties, how to define wavelength-dependent properties, and how to speed up computations using symmetries and radiation groups.
We will also present a number of predefined variables that are useful both for defining models and postprocessing operations. Among them, wall temperature variables are especially important to distinguish the temperature between two sides of a layer or between the wall temperature and the temperature in the thermal boundary layer of the fluid next to it.
This will bring us to thin structure layers and other thin structures in heat transfer models. You will learn how to choose between the different models, how to define thin structures' properties, and how to perform postprocessing operations.
You will also learn how to check the energy balance for a model or model parts using predefined variables.

- Understanding the Optimization Module
After attending this minicourse, you will know when to apply the different types of optimization available in the Optimization Module. The minicourse will include live demonstrations for simple problems, but you will also see more advanced examples from the Application Library. Sensitivity analysis is included in the COMSOL® software, and we will show how it can be used to gain more information about the behavior of your model in an efficient way.
- Advanced Topics in Structural Mechanics
In this minicourse, you will learn how to model some problems within the field of structural mechanics. The course covers contact analysis, frames, and geometric nonlinearity; combining different structural element types; and user-defined material models.
You will learn how to set up contact problems in different structural mechanics interfaces and how to apply the proper boundary conditions and solver settings. You will also get a brief overview of the concepts of geometric nonlinearity and frames.
When modeling real-world structures, you often have to combine different structural element types, such as solids, shells, and beams. In this course, you will get an introduction to the different methods for coupling such elements.
COMSOL Multiphysics® contains a large number of built-in material models for solid materials. If these are not sufficient, you can add your own models using several different methods. Here, you will learn how to do so by equation-based modeling and programming in C.
