  • By Double Precision Consultancy

    Material models in the simulations that we run need populating with reliable material data. However, if unavailable, obtaining the mechanical material properties of metals (plasticity parameters, for example) using conventional mechanical testing equipment can be cumbersome, expensive, and time consuming. A new method, developed by scientists from the University of Cambridge, has recently emerged as an alternative. Termed "indentation plastometry", the method is simpler, quicker, and cheaper than conventional mechanical testing methods; for instance, metal stress-strain curves can be obtained in just a few minutes, using small samples with minimal preparation. In this workshop, we’ll review the underlying methodology, and we’ll cover how we leveraged the power of the COMSOL Multiphysics® software, cloud computing, machine learning, and COMSOL Compiler™ to support the development and release of a commercially available indentation plastometer for our client, Plastometrex. We will also perform a live demonstration of the indentation plastometer in operation.


  • This minicourse gives you further details of the most important solver methods for multiphysics problems when using the finite element method with the COMSOL Multiphysics® software. We discuss some methods, like iterative linear solvers, that are of uttermost importance for most 3D simulations.


  • 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.


  • This minicourse is focused on modeling all kinds of transducers. The transduction from an electric signal to an acoustic signal, including the mechanical path, is a true multiphysics application. We will set up a simple model using the built-in multiphysics couplings and also look at other modeling techniques, like combining lumped models with FEM or BEM. The analysis can be done in the frequency domain or extended to the time domain, where nonlinear effects can be included. You will also learn about recent news and additions to the COMSOL Multiphysics® software relevant to the topic. Application areas include, but are not limited to, mobile devices, piezotransducers, loudspeakers, headsets, and speaker cabinets.


  • Layered materials are designed to define simple to advanced layered structures that are usually too thin to be explicitly represented in the geometry. Learn how to use the preprocessing tools to define and visualize layer thickness, orientation, and material properties. The layered material functionality is supported for structural mechanics, heat transfer, and electric current simulation. This minicourse will show how to define single-physics and multiphysics models on a layered material and how to use the dedicated postprocessing features, like volume, surface, and through-thickness plots.

  • Solving large and complex finite element models can take significant time and computational resources. 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.


  • 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 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, you will learn how to model problems within the field of structural dynamics. The course covers eigenfrequency analysis, frequency-domain analysis, time-domain analysis, and modal superposition. You will learn how to select appropriate and efficient methods. Damping models, nonlinearities, linearization, and prestressed analysis are other important topics. You will also get a brief overview of the Multibody Dynamics Module and Rotordynamics Module.

  • 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.


  • 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.


  • Topology optimization is a method by which you can come up with entirely novel designs. By allowing the material distribution within the modeling domains to be a distributed variable field, you can let the software come up with entirely new designs. You can use shape optimization to improve the performance of an existing product or as a postprocessing step for topology optimization. Come and learn how to quickly set up and solve such models.

The course gives an overview of the dG-based physics interfaces available in the Acoustics Module and applications in which their use is beneficial, including ultrasound transducers, nondestructive testing, and geophysics.

    We will discuss the distinctive features of the dG method with respect to discretization, mesh, and solvers. You will learn how to set up single-physics and coupled linear elastic/acoustics models, handle nonconforming meshes, and treat material discontinuities.


  • This minicourse will focus on how to interface the MATLAB® and COMSOL Multiphysics® software. Learn how to use MATLAB® as a scripting interface to implement and solve your COMSOL Multiphysics® simulation, export or import your data at the MATLAB® command prompt, and define model properties such as boundary conditions or material definitions within an m-function.


  • 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 discuss different examples in order to help identify cases where thermal radiation has to be accounted for. Then, we will present the different physics interfaces for radiation modeling. Surface-to-surface radiation modeling capabilities will be described in detail. In particular, the options to define gray radiation and multiple spectral bands will be explored. The different types of surfaces (diffuse, specular, and semitransparent) will be presented as well.
