A base simulation file has been prepared for this analysis. Continue by copying the file from the Simcenter STAR-CCM+ installation directory, starting the simulation, loading the base simulation file and saving it under a different file name.
Display the geometry scene.
The meshing models and mesh reference values for this simulation have already been set up. A volumetric control has been created for mesh refinement, to capture the separation behind the cylinder, and to capture the vortex shedding.
It is only necessary to set the Mach number of the freestream boundary, as all other settings have acceptable default values.
Create a plane section through the part with which to display the scalar and vector quantities while the solvers are running.
Create a scalar scene to display the velocity magnitude contour on the plane section.
Create a scalar scene to display the Wall Y+ scalar field.
By default Simcenter STAR-CCM+ provides a residuals plot which can be used to monitor the convergence of the solution. In addition to this, it is useful to create additional reports and monitors to help in assessing convergence.
Set the Maximum Steps as stopping criterion for this simulation.
Before running the simulation, reorder the mesh to optimize it for the solver.
View the Velocity Magnitude Contour and Wall Y+ Contour scenes.
The Broadband Noise Source models are intended to be used as tools for qualifying a volume mesh before a transient acoustic analysis. They are applied in the post-processing stage of a preliminary steady analysis.
The cylinder and cone refinements seem sufficient in terms of capturing the aeroacoustics sources behind the cylinder (as the Proudman source plot illustrates). Typically, however, the peak of the human hearing range is between 1-3 kHz. Therefore, refine the mesh further to increase the resolvable frequency.
Continuing from the cylinder.sim file, you now create a cylindrical part, 0.02 m in radius, which defines the outer extent of the region to be refined.
Set a new value for Maximum Steps.
The simulation is now ready to be run.
Visualize the updated Mesh Frequency Cutoff scene in the Graphics window.
This tutorial demonstrated how to set up aeroacoustics problems in Simcenter STAR-CCM+, using the flow around a cylinder.
In the previous section of this tutorial, you completed the steady-state analysis runs for qualifying the volume mesh. In this section, continuing from the previous simulation file, you set up the final transient run for an unsteady analysis of the near field and an FW-H analysis of the far field.
This tutorial compares the Post FW-H model with the FW-H On-The-Fly model.
Several further analyses are possible using the simulation history file from the earlier tutorial, DES and FW-H On-The-Fly: Noise from a Cylinder (Unsteady Analysis). These analyses are covered in this tutorial.
This tutorial demonstrates how to set up an acoustic wave simulation in Simcenter STAR-CCM+. The flow around a cylinder is used in the simulation to describe the required steps.
Noise generated by the air handling components in heating, ventilation, and air conditioning (HVAC) systems is a large contributor to interior cabin sound levels. Investigating the sources of noise and modifying the design accordingly, leads to better and quieter systems.
Unsteady aeroacoustics simulations require effective non-reflective boundary conditions to prevent spurious reflected acoustic waves from the boundaries of the computational domain interfering with the aeroacoustic results.
