This model demonstrates the motion of a bicycle with a hands-free rider when given an initial forward velocity and perturbed with a lean about the forward axis. This is implemented through the Multibody Dynamics module in COMSOL. The wheels of the bicycle have been modelled assuming ... 詳細を見る

This tutorial studies tissue heating induced by high-intensity focused ultrasound (HIFU). The nonlinear propagation of the HIFU signal is modeled using the Nonlinear Pressure Acoustics, Time Explicit physics interface. In this example, the source amplitude is sufficient to generate ... 詳細を見る

This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). 詳細を見る

This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... 詳細を見る

This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... 詳細を見る

Crimping is the plastic deformation process used to form an electrical joint between a stranded conductor and a terminal. The process involves complex multi-surface contact, including self-contact, as the terminal sleeve is plastically deformed around the wire strands. This example ... 詳細を見る

This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. 詳細を見る

This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... 詳細を見る

Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... 詳細を見る

In this tutorial the geometry of an occluded ear-canal simulator is optimized to match the acoustic response of a given ear. The target data in this model stems from a simulation of an ear canal, but it can also be based on measurements, or a response specified by a standard. 詳細を見る
