Eigenmodes in the Presence of Flow using Linearized Navier-Stokes: Annulus Geometry with Shear Flow
Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... Read More
Zero Pressure Gradient 2D Flat Plate
This model is a verification case to attest the behavior of turbulence models and wall functions in the boundary layer of a turbulent flow. The velocity and the temperature are compared to the theoretical curves in a wall-resolved and a wall-modeled approach using the Algebraic y+ ... Read More
Light Diffusion in a Slab of Particles
This tutorial model shows how to use the Heat Transfer with Radiation in Absorbing-Scattering Media multiphysics interface to model light diffusion through a slab of particles, with the corresponding heating due to absorption and scattering. The numerical results are compared to an ... Read More
Optimization of a Crane Link Mechanism
In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... Read More
Sound Radiation from Circular Duct with Flow
Model of the sound radiation from a circular duct with flow. The convected acoustic problem is described using the linearized potential flow (LPF) equations. The acoustic inlet is treated including higher order modes by combining the Port boundary condition and a Boundary Mode analysis. ... Read More
Holographic Page Data Storage Simulation
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... Read More
1D Plane Slider Bearing
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Dynamics of a Hopping Hoop
In this example, the dynamics of a hopping hoop is simulated. A rigid rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. The effects of different parameters like initial velocity and friction are explored. You ... Read More
Geometric Parameter Optimization of a Tuning Fork
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Pro/ENGINEER via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
