This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... 詳細を見る

This tutorial illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. 詳細を見る

アルカリ水電解は, 水素ガスを生成するための確立された工業プロセスです. セル内では, 陰極で水素ガスが, 陽極で酸素ガスが生成されます. 電解液は水溶液であり, 発生したガスが泡状になると, 実効イオン伝導率が低下します. また, 発生したガスは, 電極反応がアクセス可能な表面積を減少させることから, セルの性能に悪影響を及ぼす可能性があります. この例では, ガス生成がアルカリ電解セルの性能に与える影響を調査します. 詳細を見る

This example analyzes the deformation of a feeder clamp under stress. The clamp secures a feeder that carries high-frequency electromagnetic fields, and it is important that it remains as straight as possible. Forces on the clamp include both those from the feeder as well as those on the ... 詳細を見る

A deceptively simple system of two species and two reactions, describing the autocatalytic conversion of a substance, is shown to display a surprisingly exotic behavior. Starting from a 0D CSTR description, a 2D reaction-diffusion problem is formulated showing rich patterns stemming from ... 詳細を見る

This is a model of acoustic absorption by a porous acoustic open cell foam. In porous materials the sound propagates in a network of small interconnected pores. Because the dimensions of the pores are small, losses occur due to thermal conduction and viscous friction. Acoustic foams are ... 詳細を見る

This example shows how to estimate the permeability of a porous material by creating a detailed fluid flow model in a small unit cell. The result of the model is a lumped permeability of the material, which can be used in homogenized models using Darcy's law or the Brinkman equations. ... 詳細を見る

This model solves the Testing Electromagnetic Analysis Methods (TEAM) problem 7, “Asymmetrical Conductor with a Hole”—a benchmark problem concerning the calculation of eddy currents and magnetic fields produced when an aluminum conductor is placed asymmetrically above a multi-turn coil ... 詳細を見る

A slope stability analysis is performed and the Factor of Safety of the dam embankment is calculated by using the Shear Strength Reduction Technique. The pore pressure in the soil is computed based on Darcy’s law, and the Mohr–Coulomb constitutive model is used to describe the ... 詳細を見る
