The Helmholtz filter is a popular technique for imposing a minimum length scale in structural topology optimization, but certain applications also call for a maximum length scale. This model demonstrates how to achieve this using an extra PDE filter. En savoir plus
This tutorial shows an approach to model the acoustic scattering off a submarine including the outer hull. The flooded volumes between the outer hull and the pressure hull are modeled with Pressure Acoustics, Frequency Domain (FEM) and the outside water domains with Pressure Acoustics, ... En savoir plus
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time ... En savoir plus
The model shows how to calibrate the probability distribution of the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement for different values of the prescribed displacement. The model is based on synthetic data ... En savoir plus
This example is a variant of the Composite Thermal Barrier tutorial and shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Lumped Thermal System ... En savoir plus
A bow-tie antenna patterned on a dielectric substrate is optimized by adjusting the length of the arms and the flare angle to reduce the magnitude of S11, reflection coefficient. The two geometric dimensions used as design variables directly control the antenna's size and shape, and also ... En savoir plus
In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

The fluid flow in seals causes a strong restoring radial force, opposing the shaft motion. Also, there is a cross coupled force due to the axial variation of the circumferential flow. The first type of force always has a stabilizing effect on the rotor, whereas the second one in certain ... En savoir plus
This model shows how to model the avalanche breakdown due to the impact ionization in a Silicon Carbide diode. The current-voltage (I-V) characteristics of the device are presented as well as the electric field distribution plot. Furthermore, the carrier generation term has been computed ... En savoir plus
In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced. ... En savoir plus
