Introduction to Conjugate Heat Transfer Modeling in COMSOL Multiphysics®
With COMSOL Multiphysics® and the add-on Heat Transfer Module, you can simulate conjugate heat transfer with laminar flow or turbulent flow. In this article, we provide a comprehensive introduction to single-phase flow, conjugate heat transfer modeling. Read more [Picture source: COMSOL, Inc. on linkedin.com]
How to Define Load Cycles in Battery Models
When modeling a battery system, specifying a load profile is critical for accurately representing how the battery will operate in a real-world scenario. In the COMSOL Multiphysics® software and the Battery Design Module, several approaches are available to accommodate such profiles in your battery model. This blog post discusses these approaches and elaborates on their implementations. To demonstrate…

Modeling Absorption and Scattering of Collimated Light
When a ray of collimated light, such as from a laser, is incident upon a semitransparent medium, it can experience both absorption and scattering. This means that the incident light is both converted to thermal energy and redirected. Under certain assumptions, these phenomena can be modeled using a diffusive approximation in the COMSOL Multiphysics® software. This modeling…
How to Model Periodicity in Microfluidic Systems
In microfluidic systems, fluid flow is always laminar. This is both a benefit and a burden — a benefit because the flow field is stationary, and a burden because species mixing occurs primarily by diffusion, which can be time-consuming. A simple way to mix chemical species in a microfluidic chip is to use a serpentine channel…
Tracking Eigenmodes over Parameter Sweeps
Eigenfrequency analysis is an integral part of the numerical modeling toolkit. The eigenmodes of a linear system often have distinct qualitative characteristics and evolve differently over a parameter range, such as frequency. We are often asked if there is a way to keep track of and categorize these families of eigenmode solutions over the parameter sweep….

Modeling the Differential Quenching of a Katana
The katana is a legendary sword used by the samurai several hundred centuries ago. It is perhaps most recognizable for its curved shape and its remarkably sharp single edge. In this blog post, we will go over how to build a simple model of a katana using the COMSOL Multiphysics® software and simulate a differential hardening process to…

Structural Contact Modeling Guideline
Structural contact modeling is a highly nonlinear problem. As surfaces come in and out of contact, load paths and stress states will abruptly change. The computational solvers in the COMSOL Multiphysics® software are designed to work with sufficiently smooth solutions, so solving such models is inherently challenging. To efficiently achieve a converged solution, most contact models will require some changes to the…
