The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and ... Mehr lesen
In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... 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 ...

This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Mehr lesen
Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... Mehr lesen
Example for a geometry sequence to create a ship hull using Loft. The different cross sections are defined using Dimensions and Constraints. Mehr lesen
This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". Mehr lesen
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... Mehr lesen
This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes ... Mehr lesen
This small tutorial model studies energy conservation in a small conceptual test setup. The model has an inlet and outlet (modeled using ports) and a Helmholtz resonator with a very narrow neck. The acoustics in the narrow neck are modeled with Thermoviscous Acoustic for a detailed ... Mehr lesen
