Parameter Estimation with Covariance Analysis

When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... 詳細を見る

Shape Optimization of an Acoustic Demultiplexer with 4 Ports

A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... 詳細を見る

Ear-Canal Simulator Optimization

In this tutorial the geometry of an occluded ear-canal simulator is optimized to match the acoustic response of a given ear. The target data in this model stems from a simulation of an ear canal, but it can also be based on measurements, or a response specified by a standard. 詳細を見る

Optimization of a Truss Tower

Gradient based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ... 詳細を見る
