Notez que de nombreux exemples présentés ici sont également accessibles via la Bibliothèques d'Applications intégrée au logiciel COMSOL Multiphysics® et disponible à partir du menu Fichier.
This tutorial example is kindly provided by Dr. James Ransley at Veryst Engineering, LLC. This model continues from the base model “A Micromachined Comb-Drive Tuning Fork Rate Gyroscope”, which is also provided by Dr. Ransley. The model demonstrates how to accurately compute the effects ... En savoir plus
These models demonstrate the implementation of a Helmholtz filter to: Smooth noisy input data to a transient simulation Smooth spatially varying data over an arbitrary surface Generate a mesh that is adapted to the spatial variation of an input load Learn more in the accompanying ... En savoir plus
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... En savoir plus
A detailed description of these models can be found in our blog post “How Should I Evaluate Singular Stress Fields?”. The models are: notchedStrip.mph – Model for the initial studies of the stress field properties. singularityPower.mph – Small model solving the transcendental equation ... En savoir plus
Cupric ions show a strong affinity to ammonia in aqueous solutions, forming strongly colored deep blue complexes. The relative amounts of the different ammine ligand complexes, with varying coordination numbers, are governed by the stability constants of the equilibria forming the ... En savoir plus
Active aerodynamics systems actuate components on a vehicle dynamically to improve fuel efficiency, optimize cooling, and enhance stability. A drag reduction system (DRS) is an example of an active aerodynamic technology, which is often used in Formula 1® cars to overtake other cars ... En savoir plus
This example is a variant of the Composite Thermal Barrier tutorial and shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Lumped Thermal System ... En savoir plus
This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... En savoir plus
This example minimizes the mass of a bracket that is synchronized from Inventor® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features is ... En savoir plus
Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ...
