This model utilizes the thermoviscous acoustic interface in a sub-model to obtain detailed results for the transfer impedance of a perforated plate (including the thermal and viscous losses). The impedance is in turn used as an internal impedance in a pressure acoustic model of a ... Read More
This model demonstrates the transient heating of a sample of material with a time- and space-varying heat load. Issues of solution accuracy with respect to mesh and solver tolerance can be quickly studied on this model. Learn more about this model in the accompanying blog post: "Intro to ... Read More
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. Read More
This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution. Read More
Extending the Tuning Fork model, this example shows how to set up an Optimization Study to determine the prong length at which the fork vibrates at the standard concert pitch, 440 Hz. Read More
This model shows how to use the Metal Processing Module and the Optimization Module to calibrate parameters of a phase transformation model against TTT (Time Temperature Transformation) data. Read More
Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps: The ... Read More
For more than 50 years, it has been known that neutrally buoyant particles in a flow channel tend to converge to specific locations in the channel cross section. For a cylindrical pipe, or two parallel planes carrying a Poiseuille flow, the equilibrium position is about 0.6 times the ... Read More
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... Read More
This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator. Read More
