In-Plane Framework with Discrete Mass and Mass Moment of Inertia
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared with the values given by an analytical expression.

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.
Rotating Plate in a Unidirectional Molecular Flow
This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows.
Gross–Pitaevskii Equation for Bose–Einstein Condensation
This tutorial model solves the Gross–Pitaevskii Equation for the ground state of a Bose–Einstein condensate in a harmonic trap, using the Schrödinger Equation physics interface in the Semiconductor Module. The equation is essentially a nonlinear single-particle Schrödinger Equation, with a potential energy contribution proportional to the local particle density. The eigenvalue study is not ...
Micromechanical Model of a Composite - new
In this example, a simplified micromechanical model of a unit cell with periodic boundary conditions is analyzed. The homogenized elastic and thermal properties of a composite material are computed based on individual properties of fiber and matrix. A comparison of numerical values are made against values obtained from the Rule of Mixture.

Geometric Parameter Optimization of a Tuning Fork
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Pro/ENGINEER via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.
Piezoelectric Energy Harvester
This model shows how to analyze a simple, cantilever based, piezoelectric energy harvester. A sinusoidal acceleration is applied to the energy harvester and the output power is evaluated as a function of frequency, load impedance and acceleration magnitude.
Thermoelectric generator
In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example 3) and a good match was observed. Ref : "Multiphysics Simulation of Thermoelectric Systems - Modeling of ...
Forced Vibration Analysis of a Composite Laminate - new
Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions can trigger the initiation and propagation of layer separation. This leads to degraded structural performance and sometimes even complete failure of the structure. This example considers the response of a ...
