The following features are introduced: - The Fundamentals: A Static Linear Analysis - Parametric study - Including Initial Strain - Modeling Thermal Expansion - Adding Rigid Connector - Adding Spring Conditions - Modeling with the Shell Physics Interface - Transient Analysis - ...

Vibrating Beam in Fluid Flow

A classical flow pattern is the von Kármán vortex street that can form as fluid flows past an object. These vortices may induce vibrations in the object. This problem involves a fluid-structure interaction where the large deformation affect the flow path. The magnitude and the frequencies of the oscillation generated by the fluid around the structure is computed and compared with the values ...

Fluid-Structure Interaction in a Network of Blood Vessels

This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel walls. The complete analysis consists of two distinct but coupled procedures: a fluid-dynamics ...

Heating Circuit

Small heating circuits find use in many applications. For example, in manufacturing processes they heat up reactive fluids. The device used consists of an electrically resistive layer deposited on a glass plate. The layer causes Joule heating when a voltage is applied to the circuit. The layer’s properties determine the amount of heat produced. This multiphysics example simulates the ...

Piezoacoustic Transducer

A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that require the generation of sound in air and liquids. Examples of such applications include phased array microphones, ultrasound equipment, inkjet droplet ...

Vibration Analysis of a Thick Beam

This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results.

Thermal Actuator

This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. In this model version, the geometry is parameterized so that the effect of varying the actuator's dimensions can be analyzed.

Acoustic-Structure Interaction

Liquid or gas acoustics coupled to structural objects such as membranes, plates or solids are important applications in many engineering fields. This model is a general demonstration of an acoustic fluid phenomenon in 3D that is coupled to a solid object. The walls of the solid object are impacted by the acoustic pressure. The frequency response from the solid is calculated, which is then fed ...

Large Deformation Analysis of a Beam

This example studies the deflection of a cantilever beam undergoing very large deflections. In addition, a linearized buckling analysis of the structure is also performed. The model comes from Section 5.2 of NAFEMS Background to Finite Element Analysis of Geometric Non-linearity Benchmarks.

Piezoelectric Shear-Actuated Beam

The model performs a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface. Inspired by work done by V. Piefort and A. Benjeddou, it models a sandwich beam using the shear mode of the piezoelectric material to deflect the tip.
