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 tutorial example shows how to set port features in a physics interface when designing a grounded coplanar waveguide (GCPW) circuit that is useful for mmWave applications. En savoir plus
This app demonstrates the following: Geometry parts and parameterized geometries Sending an email with a report when the computation is finished User-defined email server settings which is useful when running compiled standalone applications Options for setting different mesh sizes ...

This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, for instance from solid to liquid, energy is added to the solid. Instead of creating a temperature rise, the energy alters the material’s molecular ... En savoir plus
A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares to the Fresnel equations. En savoir plus
Imagine that you are designing a light-weight mountain bike frame that should fit in a box of a certain size and should weigh no more than 8 kg. Given that you know the loads on the bike, you can achieve this by distributing the available material while making sure that the stiffness of ... En savoir plus
We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... En savoir plus
Marangoni convection occurs when the surface tension of an interface (generally liquid-air) depends on the concentration of a species or on the temperature distribution. In the case of temperature dependence, the Marangoni effect is also called thermo-capillary convection. The Marangoni ... En savoir plus
The fluid flow in seals causes a strong restoring radial force, opposing the shaft motion. Also, there is a cross coupled force due to the axial variation of the circumferential flow. The first type of force always has a stabilizing effect on the rotor, whereas the second one in certain ... En savoir plus
Solar concentrator/cavity receiver systems can be used to focus incident solar radiation into a small region, generating intense heat which can then be converted to electrical or chemical energy. A common figure of merit in solar thermal power systems is the concentration ratio, or the ... En savoir plus
