This model shows how to create dispersion diagrams from simulation results by extending the tutorial Thin-Film BAW Composite Resonator. The dispersion curve can be plotted against both real and imaginary values of the wave number, corresponding to the propagating modes and evanescent ... 詳細を見る

This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... 詳細を見る

This example shows how to model a deep excavation. The main application area of this type of modeling is in civil engineering. In this case, the in situ lateral pressure acting on the retaining wall during the soil excavation is modeled with boundary loads. The soil assumes Drucker ... 詳細を見る

This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced ... 詳細を見る

This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... 詳細を見る

This example demonstrates how to use a background field in a sound scattering problem. The application is an acoustic invisibility cloak made of a metamaterial. Two different types of metamaterials are used, one using an anisotropic acoustic material with varying properties and one using ... 詳細を見る
