This is one of the two models from the blog post about heat transfer in the subsurface: Coupling Heat Transfer with Subsurface Porous Media Flow Note: Poroelasticity is not included here. En savoir plus
This example shows the modeling of a resin transfer molding (RTM) process for a wind turbine blade using the Two-Phase Flow, Level Set, Brinkman Equations interface. Resin is injected into a preform consisting of different composites with different anisotropic permeabilities. En savoir plus
This tutorial demonstrates how to integrate multiple Lumped Battery models into the Electrical Circuit interface. Two batteries are connected in series. Each battery is protected by a shunt resistances that is activated if the battery state-of-charge reaches below a certain threshold ... En savoir plus
This tutorial model solves a two-component Schrödinger equation for the eigenstates of a simple silicon quantum dot in a uniform magnetic field, based on the paper by Jock et al. on the topic of spin-orbit qubits. The built-in domain condition Lorentz Force for the Schrödinger Equation ... En savoir plus
This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... En savoir plus
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... En savoir plus
This model studies the temperature effects on the viscoelastic stress relaxation in a long thick-walled cylinder. In particular, decay of the stresses under the influence of the temperature field during a period of two hours is studied. A four-term generalized Maxwell model represents ... En savoir plus
This is a tutorial of a slot die coating process in 3D where the channel is obstructed. The example uses a two-phase flow phase-field method with a non-Newtonian power-law fluid. The effects on the film thickness of the channel obstruction can clearly be seen. En savoir plus
This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. En savoir plus
Power lines are commonly used as a means of transmitting electrical power across large distances. In this tutorial, towers transmitting high voltage three-phase AC power are modeled, and the resulting magnetic field is computed. The towers have two shielding lines. En savoir plus
