This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... En savoir plus
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... En savoir plus
When electrical energy is converted into mechanical work in an electrical motor, the "wasted" energy that causes device heating is usually referred to as loss. The ratio of useful work to input energy, or the efficiency of the motor, is an important property for the overall energy ... En savoir plus
The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and ... En savoir plus
In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... En savoir plus
This version of the balloon inflation example demonstrates how the Shell and Membrane interfaces can be used to model thin structures made of hyperelastic materials. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane ... En savoir plus
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. En savoir plus
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... En savoir plus
This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... En savoir plus
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association ... En savoir plus
