This tutorial introduces a workflow typical of creating geometry for simulation by using Sketch mode to draw complex shapes. Follow the step-by-step instructions to draw the geometry for the analysis of a light bulb. The physics setup is described in the model Free Convection in a Light ... Mehr lesen
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 ... Mehr lesen
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... Mehr lesen
A dielectric resonator placed near a radiating element can be used to increase directivity and gain. Here, a block of quartz dielectric, with additional passive metallic antenna elements, is placed above a slot antenna. The fields in and around the antenna are solved for. The far field ...

Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... Mehr lesen
The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... Mehr lesen
In this tutorial you will learn how to use selections when creating the parametric geometry for the analysis of a steam reformer, and set up the selections needed for the physics definitions. The multiphysics analysis of the steam reformer is described in the model Steam Reformer found ... Mehr lesen
This example exemplifies how to model the Beer-Lambert law using the core functionality of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Laser-Material Interactions with the Beer-Lambert Law". Mehr lesen
Trusses are structural members that can only sustain axial forces, but no bending or torsion. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This ... Mehr lesen
Die Ersatzmodell-App Thermischer Aktuator zeigt, wie Sie die Berechnung für Multiphysik-Analysen mithilfe eines Ersatzmodells beschleunigen können. Ein Ersatzmodell ist ein einfacheres, in der Regel rechnerisch günstigeres Modell, das zur Annäherung an das Verhalten eines komplexeren und ...
