This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of ... En savoir plus
The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to ... En savoir plus
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 ... En savoir plus
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... En savoir plus

In this example, phase transformation data and phase material properties are imported from JMatPro, and used to compute CCT curves. Dilatometry curves (axial thermal strain) are computed across a range of cooling rates. En savoir plus
This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Amazon Elastic Compute Cloud™ (EC2™). This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager ... En savoir plus
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". En savoir plus
This space-dependent model describes a stirred semibatch reactor used for producing antibody–drug conjugates. The reactor is set up in 3D and the conjugation reactions, turbulent flow, and concentration fields are simulated as functions of time. The resulting yield and drug-to-antibody ... En savoir plus
In this model, a linear magnetic gear system with a gear ratio of 11:4 is modeled. The liner magnetic gear is assumed to be infinitely long with the modular structure that is repeating on either side. Only a single modular section is modeled by using the customized linear periodic ... En savoir plus
