New and Updated Models, Apps, and Add-ins in Version 6.4
Point Source in a 2D Jet: Radiation and Refraction of Sound Waves Through a 2D Shear Layer
This is a new benchmark model for the linearized Euler physics interfaces. The model results are compared to data from a NASA benchmark.
Helmholtz Resonator with Flow: Imported Fluid Flow from CGNS Data
This tutorial shows how to import CGNS flow data into a model using the Imported Fluid Flow interface and the CFD Data (CGNS) function. The model couples the flow to a Linearized Navier–Stokes, Frequency Domain interface with the built-in multiphysics couplings.
Generic Nacelle with an Acoustic Liner
This new tutorial model demonstrates the use of the new Brambley (finite boundary layer) impedance option available in the Linearized Potential Flow, Frequency Domain interface. The model compares the results with the detailed Linearized Navier–Stokes, Frequency Domain interface.
Porous Material Characterization from Impedance Tube Measurement
This new application is used for retrieving the poroelastic material parameters from impedance tube measurements performed on a sample. The process is based on a parameter estimation procedure.
