This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into ... 詳細を見る

This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D Solid Edge® geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL  ... 詳細を見る

Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... 詳細を見る

This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... 詳細を見る

In this example, a tensile test is simulated at four different strain rates. The Johnson–Cook hardening law is used to model the strain rate dependency of the plastic hardening. The temperature distribution and thermal expansion caused by the heating generated by the plastic ... 詳細を見る

This tutorial model demonstrates how to estimate the material parameters of a viscoplastic Bergstrom–Boyce model suitable for nonequilibrium modeling of rubber-like materials. The data used for parameter estimation consists of cyclic uniaxial tension and compression tests at two ... 詳細を見る

A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... 詳細を見る

Prior to the reliability testing, surface-mount devices (SMDs) are required to go through a preconditioning process, which represents the effects of storage and the typical reflow operation in the following board assembly process. During the preconditioning process, test samples usually ... 詳細を見る

Non-Newtonian fluids have complex flow characteristics that vary with shear rate, making their behavior in porous materials difficult to predict. Pore scale modeling captures these flow patterns at a microscopic level, helping derive properties for macroscale use. This model ... 詳細を見る

Transport which is purely diffusive in nature can be modeled using a Brownian force. This model shows how to add such a force in the Particle Tracing for Fluid Flow physics interface. Particle diffusion in a fluid is modeled with the diffusion equation and the Particle Tracing for Fluid ... 詳細を見る
