COMSOL Day: Heat Transfer in Material Processing
See what is possible with multiphysics simulation
Join us at the Online COMSOL Day: Heat Transfer in Material Processing and find out more about modeling thermal processes and different materials (metal, composite, polymer, etc) processing applications. Learn how modeling contributes to the digitalization of the material processing industry.
Get introductions to the use of FEM simulation for thermal (convection, radiation, phase change) and CFD analysis, electromagnetic heating, optimization and metallurgical phase transformations from our application engineers and developers. Selected industry experts will provide insights into their simulation projects. You will have the opportunity to exchange ideas with colleagues interested in simulation and COMSOL developers in dedicated Tech Café sessions.

To start, we will briefly discuss the format of the day and go over the logistics for using GoToWebinar.
Heat transfer is a key factor to include in the simulation of material processing for high-fidelity results, making multiphysics simulation not only useful but also necessary. In this opening session, we will exemplify applications where heat transfer modeling can be applied to real-life applications around polymer flow, metal processing, composite material behavior, and battery design. We will then discuss how optimization can be used to develop more energy-efficient processes and how COMSOL Multiphysics® can help to deploy ready-to-use applications to model real-world applications.

The presentation will show which physics need to be modeled to develop and understand processes involving molten metal, such as welding and additive manufacturing. After a quick review of the equations, some examples will be provided for different technologies already modeled. Finally, the focus will be on wire arc additive manufacturing (WAAM). For the first time, a fully coupled 3D model describes electromagnetism, heat transfer, and fluid flow in the wire, droplet, arc, and melt pool. Particular attention will be paid to the free surface description and tricks used to reduce calculations times.

Well known by their lightness and their excellent thermomechanical properties, high-performance thermoplastics composites are used to manufacture parts for the aeronautics and automotive sectors. These materials have a relatively high melting point compared with other polymers, which allows non-negligible temperature differences during their processing. These temperature variations, when not properly controlled, could generate thermal stresses, shrinkage, waviness, delamination, and other thermal-related problems that could lead to total material damage or a reduction of material quality. To overcome this challenge, a thermal design methodology using COMSOL Multiphysics® and LiveLink™ for MATLAB® is proposed to determine a proper heat flux as a time and space distribution, during the different stages of a manufacturing process. The methodology, based on the conformal cooling approach, uses a combination of a deterministic inverse optimization algorithm and a stochastic particle swarm optimization algorithm implemented in LiveLink™ for MATLAB®.
Get an overview of the COMSOL Multiphysics® software and explore its capabilities for modeling heat transfer in material processing applications. This session will take you through the process of building and running a model that illustrates the different functions and features of the COMSOL Multiphysics® software. You will also see how you can transform models into simplified and specialized applications that can be used by engineers and scientists not familiar with simulation software.
Phase change is often present in materials processing and has effects in terms of the energy required for (or to be removed from) the process, and also in terms of the properties for the final product. COMSOL Multiphysics® provides different tools to account for phase change effects. Join this Tech Café to interactively discuss the simulation challenges associated with these effects and processes with users, COMSOL engineers, and developers.
This session will introduce you to modeling the multiphysics of phase transformations and quenching of metals like steel using COMSOL Multiphysics®. With the introduction of the Metal Processing Module to the COMSOL® software product suite, it is now much easier to model solid-state metallurgical phase transformations that are affected by and dependent on other physical phenomena, as well as the resulting material behavior of the transformed metal. In addition to covering the modeling of metallurgical phase transformations and hardening, the presentation will also introduce the new Carburization physics interface and new functionality for importing material properties.
This session focuses on the modeling of nonisothermal flow with conjugate heat transfer in COMSOL Multiphysics® and its add-on products. Simulations of various types of flows, ranging from incompressible flow, where buoyancy effects can be modeled using the Boussinesq approximation, to fully compressible transonic and supersonic flow, are easily set up using the predefined physics interfaces and multiphysics couplings. When turbulent flow is simulated using a RANS (Reynolds-averaged Navier–Stokes) model, turbulent heat diffusivity and conjugate heat transfer models are automatically included in the formulations. We will also address modeling flows of non-Newtonian fluids, where temperature variations may induce strong shear thinning or thickening effects in these fluids.
Heat transfer is integral to material processing and can often be the crucial factor for enabling such. This panel discussion will discuss how multiphysics simulation that includes heat transfer can improve such processes and the quality of the material being made. Experienced simulation engineers from industry will discuss with the technical product manager for the Heat Transfer Module what current trends and future expectations are envisioned within this type of modeling. The panel will also take questions and comments from the audience.

During this session, you will learn how to include surface-to-surface radiation in your models. In particular, you will learn how to define the surface properties and direction of the radiation transmission; use domains and layer opacity properties; and define temperature-, wavelength-, and direction-dependent properties. The session will also include a discussion of situations where radiation is most likely to play a significant role in the overall heat transfer of a material processing application.
Understanding processes and improving products are two common motivations for performing simulations. It is often beneficial to replace trial & error with more systematic techniques. In this Tech Café, we will discuss parameter estimation and other optimization problems that can be solved with the Optimization Module.
