This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. A 3D impeller with eight identical blades can be divided into eight sectors of symmetry. The model computes the fundamental frequencies for the full impeller geometry and ... En savoir plus
This tutorial model shows a system consisting of a Helmholtz resonator on the side of a main duct. The resonator volume is partly filled with a porous material. The model computes the reflection, transmission, and absorption of the system. Thermoviscous losses are included in the model ... En savoir plus
Silicon carbide (SiC) epitaxial furnaces are a specialized equipment for the production and preparation of SiC epitaxial wafers. This example model demonstrates the process of preparing an SiC epitaxial wafer based on the physical vapor transport (PVT) method in a furnace. This involves ... En savoir plus
A demonstration of topology optimization using the Structural Mechanics Module and the Optimization Module. The classical MBB beam is solved in 2D using a Helmholtz filter and Solid Isotropic Material Penalization (SIMP) technique to recast the original combinatorial optimization problem ... En savoir plus
The present model example is based on Copper Deposition in a Trench model available in Electrodeposition Application Library. The nonuniform deposition along the trench surface leads to formation of a cavity/void. Since the Deformed Geometry interface cannot handle topological changes, ... En savoir plus
Swirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still included in the equations. This example shows the ... En savoir plus
Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... En savoir plus
Density variations can initiate flow even in a still fluid. In earth systems, density variations can arise from naturally occurring salts, subsurface temperature changes, or migrating pollution. This buoyant or density-driven flow factors into fluid movement in salt-lake systems, saline ... En savoir plus
This model how to build and solve a conductive heat transfer problem using the Heat Transfer interface. The model, taken from a NAFEMS benchmark collection, shows an axisymmetric steady-state thermal analysis. As opposed to the NAFEMS benchmark model, we use the temperature unit kelvin ...

Quantum dots are nano- or microscale devices created by confining free electrons in a 3D semiconducting matrix. Those tiny islands or droplets of confined “free electrons” (those with no potential energy) present many interesting electronic properties. They are of potential importance ... En savoir plus
