A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... En savoir plus
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... En savoir plus
This model demonstrates how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ... En savoir plus
The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... En savoir plus
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. En savoir plus
This example model simulates the long-path echo of trumpet sounds reflected from a building 500 m away. The echo can only be heard at night because of the acoustic ray refraction in the atmosphere with different temperature profiles. The model is solved using the ray tracing in the ... En savoir plus
