The dispersion curves for a fluid-filled pipe with elastic walls are computed and compared with the analytical results for a pure elastic and an acoustic waveguide, respectively. Results show good agreement and also provide insight into the dynamics of the fluid-filled pipe at low and ... En savoir plus
In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. ... En savoir plus
Circulating fluidized beds are widely used in the food & beverage, pharmaceutical, chemical, and energy industries to achieve efficient contact between solid and fluid reactants. This model visualizes how a circulating fluidized bed operates. In the model, the dispersed phase, which ... En savoir plus
The Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only ... En savoir plus
Computing molecular flows in arbitrary geometries produces complex integral equations that are very difficult to compute analytically. Analytic solutions are, therefore, only available for simple geometries. One of the earliest problems solved was that of gas flow through tubes of ... En savoir plus
This example consists of a 2D analysis of propagation modes in the chamber of a muffler. In this case, the muffler walls are considered to be made of a linear elastic material and account for their influence on the modes propagating through the cross section of the chamber. This analysis ... En savoir plus
The Curve Digitizer application can be used to digitize/extract curves from images. This application provides an easy way to digitize a variety of 1D plots with different axes in Cartesian or Polar coordinate system. After a curve image is imported, the digitization is done in a few ... En savoir plus
A Butler matrix is a passive beamforming feed network. It is a cost-effective feed network for phased array antennas because the circuit can be fabricated in the form of microstrip lines and is a viable solution for performing beam scanning without deploying expensive active devices. ...

In this tutorial model, the far-field radiation pattern of a dipole antenna is computed in a 3D model component. Then, in a separate 3D model component, a ray is released using the far-field radiation pattern to initialize the ray's intensity, polarization, and phase. En savoir plus
In this example, the High Mach Number Flow, Low Reynolds Number k-e interface is used to compute the compressible turbulent flow from a rectangular nozzle. Mesh refinement based on the estimation of the shock strength and the shear-layer strength is employed to achieve appropriate ... En savoir plus
