This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... Mehr lesen
Bei der Bewertung der Wirksamkeit von Behandlungen für Augenkrankheiten können Modellierung und Simulation für die pharmakokinetische Analyse verwendet werden. Dazu wird die Medikamentenkonzentration und ihre Ausbreitung im Auge im Lauf der Zeit visualisiert. In diesem vereinfachten ... Mehr lesen
This model demonstrates topology optimization of a 2D heat exchanger with laminar flow. The flow is pressure driven and the objective is to maximize the heat transfer. The density method is used with the (now) classical approach of a single design variable and two flow interfaces. ... Mehr lesen
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...

Bicycle wheels are laced tangentially if they are intended to be used with disc brakes, because a radial pattern gives rise to larger forces in the rim. Otherwise, these rim forces are largely independent of the braking force. Mehr lesen
This simple benchmark model computes the potential and carrier concentrations for a one-dimensional p-n junction using both the finite element and finite volume methods. The results are compared with an equivalent device from the book, "Semiconductor Devices: A Simulation Approach," by ... Mehr lesen
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Mehr lesen
This is a conceptual model of a microphone placed in an infinite baffle (flush mounted). The purpose is to determine the free-field level correction curve of the setup, which includes the exterior domain, microphone grid, and volume between the grid and the diaphragm. The microphone ... Mehr lesen
This presentation and series of models show how to use the Deformed Mesh interfaces to model small and large translations and rotations of objects. A more detailed description of these models can be seen in the blog post Model Translational Motion with the Deformed Mesh Interfaces and ... Mehr lesen
In this model, we use the Pressure Acoustics, Boundary Elements physics interface to analyze the acoustics of a generic head and torso simulator. This is a manikin head used to do standardized measurements for hearing aids, mobile phones, and headphones. The model showcases some ... Mehr lesen
