In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... En savoir plus
In a gearbox, vibrations due to gear rattling and bearing misalignment are well known sources of noise. In this example, two shafts connected through a pair of gears are considered. The shafts are supported on roller bearings at their ends. Initially, the driven shaft is unloaded and the ... En savoir plus
This tutorial analyzes the DC characteristics of an InSb p-Channel FET, using the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without a large increase of computational resources. The confinement effect is applied both ... En savoir plus
This example demonstrates how you can use modeling to investigate the performance of different hydrodynamic journal bearings. The model uses the Hydrodynamic Bearing interface, which solves the Reynolds equation to compute the pressure developed in a thin fluid film for four different ... En savoir plus
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... En savoir plus
Most metals and alloys undergo viscoplastic deformation at high temperatures. In case of cyclic loading, a constitutive law with both isotropic and kinematic hardening is necessary to describe effects such as ratcheting, cyclic softening/hardening, and stress relaxation. The Lemaitre ... En savoir plus
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. En savoir plus
This benchmark model computes the valence band structure of an unstrained and a strained bulk GaN wurtzite crystal, as a tutorial for users who wish to set up multiple wave function components with the Schrödinger Equation interface. The model follows the formulation given in the ... En savoir plus
A gate-all-around MOSFET consists of a nanowire with a gate electrode wrapped around the circumference. Since the entire nanowire forms the channel, this configuration provides the best possible electrostatic control of the channel and offers a good candidate for the miniaturization of ...

This classical verification model solves the steady state temperature distribution in a plan disk heated by a localized heat source at its center. It shows and compare different ways to define a heat source localized on a small domain by representing it either as a geometrical point or a ... En savoir plus
