Tutorial: Broadband Noise Modeling

The purpose of this tutorial is to provide guidelines and recommendations for the basic setup and solution procedure for solving an acoustics field generated from a sedan car using the broadband noise model. The problem is initially solved for steady state, and then the broadband acoustic model is included in the calculation to perform post-processing.
Problem Description
The problem involves a sedan car model as shown in Figure 1. The car is traveling at 70 miles per hour. You will study only the acoustics field generated by the motion of the car to highlight the noise source on the sedan body, therefore the mirrors and the wheels of the car are ignored.
