This model simulates a tuning fork for tuning musical instruments which, if correctly designed, should sound the note of A, 440 Hz. It computes the fundamental eigenfrequency and eigenmode for the tuning fork. Although the example seems...
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of...
Imagine that you are designing a light-weight mountain bike frame that should fit in a box of a certain size and should weigh no more than 8 kg. Given that you know the loads on the bike, you can achieve this by distributing the available...
A demonstration of topology optimization using the Structural Mechanics Module and the Optimization Module. Three classical models are shown, the loaded knee, the Michell truss structure, and MBB beam. The optimization method is based on...
This presentation shows how to use the Optimization Module to fit a material model curve to experimental data. It is based on the hyperelastic Mooney-Rivlin material model example given in the Structural Mechanics users guide.
This model demonstrates transient optimization through the least squares solver. The model consists of a wall in 1D. The outer temperature varies over 24 hours and during this time, the inner temperature on the wall has been measured....
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution...
The optimization of components with respect to geometrical design parameters is a common task in microwave engineering. In this model the reflection coefficient of a waveguide structure is minimized, and the sensitivities of the real and...
The radial stress component in an axially symmetric and homogeneous flywheel of constant thickness exhibits a sharp peak near the inner radius. From there, it decreases monotonously until it reaches zero at the flywheel’s outer rim. The...
The impedance of an antenna is an important parameter that determines how it behaves in transmitter circuits. Impedance matching and low reactive components are important to get reliable operation, which can be achieved either by proper...
