This tutorial demonstrates how a lumped model of a MEMS transducer can be derived from its FEM model. It includes an FEM model of a capacitive micromachined ultrasonic transducer (CMUT) and the corresponding lumped model created using the Lumped Mechanical System (LMS) interface. The ... Mehr lesen
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model ... Mehr lesen
This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Curve Fitting of Experimental Data with COMSOL ... Mehr lesen
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Mehr lesen
For transient acoustic problems, there are different sound pressure level metrics that have been defined in the literature and in measurement standards. These metrics are important to know when comparing results from a transient acoustic simulation to measurements from a sound level ... Mehr lesen
This tutorial shows how to simulate coupled heat and moisture transport in an insulated roof structure, made of a load bearing and an insulation layer. The thermal insulation is facing the interior and there is a moisture barrier facing the exterior. The load bearing is capillary active ... Mehr lesen
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... Mehr lesen
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Mehr lesen
This model utilizes a continuation solver to efficiently compute the current-voltage characteristics of a corona discharge generated by a wire-to-wire configuration. It provides a flexible framework that can be easily adapted to study other discharge configurations and types. Mehr lesen
The Drift Diffusion interface solves a pair of reaction/advection/diffusion equations, one for the electron density and the other for the mean electron energy. This tutorial example computes the electron number density and mean electron energy in a drift tube. Electrons are released due ... Mehr lesen
