The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using parameter, shape and topology optimization. En savoir plus
Bulk Acoustic Wave (BAW) resonators can be used as narrow band filters in radio-frequency applications. The chief advantage compared with traditional ceramic electromagnetic resonators is that BAW resonators, thanks to the acoustic wavelength being much smaller than the electromagnetic ...

This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... En savoir plus
This example illustrates the modeling of ply drop-off in a composite panel. The panel considered for the analysis has three sections–thick, taper, and thin. The thick section plies are divided into the core, top-bottom belts, and dropped plies. The thick section of the panel has sixteen ... En savoir plus
Composite materials are often used in structural applications, where the ability to tailor properties such as stiffness and strength make them attractive compared to traditional engineering materials. In addition to structural applications, composites are also used in applications where ... En savoir plus
This problem follows a typical preliminary board-level thermal analysis. First perform a simulation of the board with some Integrated Circuits (ICs). Then, add a disk-stack heat sink to observe cooling effects. Finally, explore adding a copper layer to the bottom of the board in order to ... En savoir plus
This example illustrates multiphase flow modeling in an airlift loop reactor. The reactor is filled with water and air bubbles are injected at the bottom through two frits. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid. The model specifically investigates ... En savoir plus
This model demonstrates the use of the Heat and Moisture Flow features for the simulation of superheated steam drying of a wood particle. A nonequilibrium formulation is used to compute the transport of the liquid water and vapor phases in the wood particle. Reference: Le, K. H., ... En savoir plus
This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... En savoir plus
In this conceptual example, the soft impact between two elastic rings is modeled using the Solid Mechanics interface. One of the rings is given an initial velocity to initiate the impact event. Both rings are unconstrained and not subjected to any external forces. Contact is modeled ... En savoir plus
