Freefrom optics has generated renewed interest due to advances in fabrication and manufacturing technology. In this Application Library example, we are going to look at a specific design called the Alvarez lens where two complementary conic surfaces are shifted laterally with respect to ... 詳細を見る

The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ... 詳細を見る

Example for a geometry sequence to deduce a shell model from an imported solid CAD file. The model demonstrates how to generate parameters from dimensions of a geometry and how to convert a solid CAD geometry into a shell representation using midsurface and extract 詳細を見る

This model simulates the electrohydrodynamic (EHD) flow of a dielectric liquid around a wire electrode positioned between two parallel flat-plate electrodes. The ion transport is described using the Poisson–Nernst–Planck equations, while fluid motion is governed by the Navier–Stokes ... 詳細を見る

In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... 詳細を見る

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 ... 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

Two approaches are demonstrated to introduce a goal-seeking Global Equation into a COMSOL Multiphysics® model. This Global Equation acts to adjust a single input of the model such that any single scalar output of the model takes on a desired target value, or goal. Learn more in ... 詳細を見る

This model demonstrates the transport of grains using a screw conveyor. The grains enter the conveyor through a chute and are transported over an incline by a rotating screw. This model also demonstrates how to build and run a model method that evaluates the mass flow rate. 詳細を見る

This example demonstrates how to apply the Uncertainty Quantification (UQ) Module in COMSOL Multiphysics to analyze the performance and reliability of a simple resistor. Small variations in material properties, geometry, and manufacturing processes can significantly impact the resistance ... 詳細を見る
