The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... En savoir plus
This is a demo model to show how to model connections in a mechanical system using Multibody Dynamics interface. In this model, pantograph mechanism is modeled. The purpose of this mechanism is to produce an identical, either enlarged or miniaturized, copy of an existing drawing. En savoir plus
Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... En savoir plus
A simple way to estimate the value of π is by using a pendulum, whose oscillation period can be measured and used to calculate an approximation. This simulation app is based on a model that uses the <em>Multibody Dynamics</em> interface to describe the motion of a simple ... En savoir plus
This example shows how to model isotropic volumetric growth and atrophy of soft biological tissues. The artery is represented by a cylinder that is stretched and compressed due to an applied axial load. As a result, the tissue undergoes growth and atrophy. En savoir plus
This model describes the corrosion of magnesium (Mg) alloys in physiological environments using a phase-field formulation. The approach couples Mg dissolution kinetics with ionic transport, enabling the transition from activation-controlled to diffusion-controlled regimes to be captured. ... En savoir plus
This model analyzes the uncertainty in focused ultrasound induced tissue heating. The material properties for the tissue mimicking material, including the uncertainty, are taken from the FDA Medical Device Development Tool: Tissue Mimicking Material (TMM) for Preclinical Acoustic ...
