This example exemplifies the basics in how to optimize shapes using COMSOL Multiphysics®. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Designing New Structures with Shape Optimization". Mehr lesen
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Mehr lesen
Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... Mehr lesen
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... Mehr lesen
How the open-circuit voltage (OCV) of a lithium-ion battery varies with the state of charge is governed by various physical properties such as the thermodynamics of the electrode reactions, the relative capacities of the electrode materials, and the amount of cyclable lithium, but also ...

In this model, the packing behavior of grains is simulated using three force models: Hertz-MD, Hertz-MD with adhesion, Hertz-MD with adhesion and van der Waals forces. The packing efficiency is calculated to quantify the extent of packing observed. Mehr lesen
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... Mehr lesen
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 ... Mehr lesen
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... Mehr lesen
