Analyzing the “Muscles” of a Robotic Manta Ray

Soft robotics is a field gaining increasing interest among engineers, particularly due to its growing use in the biomedical industry. For example, as advancements in biomimicry continue to evolve and improve over time, soft robots have shown promise for applications such as prosthetics, artificial muscles, and surgical instruments. Actuators play a critical role in this field,…

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….
