This example simulates electroplating of a printed circuit board (PCB) in 3D using the Secondary Current Distribution interface. In order to achieve thickness uniformity across the PCB, a dummy pattern is included in the design, along with an aperture in the electroplating bath. En savoir plus
This is a demonstration of how to use the thermodynamics functionality in the COMSOL Multiphysics® software to make flash calculations. A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in ... En savoir plus
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... En savoir plus
This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen ...

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 ... En savoir plus
This tutorial models how the relative humidity of the inlet gases impacts the performance of a low-temperature polymer electrolyte membrane-electrode assembly. The model includes humidity-dependent ionomer (electrolyte) conductivities, gas phase mass transport and water ionomer ... En savoir plus
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... En savoir plus
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... En savoir plus
