This example shows how to set up an acoustic transfer vector (ATV) computation with *FREQUENCY_DOMAIN_ACOUSTIC_BEM_ATV and how to post-process with *DATABASE_FREQUENCY_BINARY_D3ATV. In the file domgeom.k the domain decomposition can be studied. Example 8.10 from LS-Dyna training class NVH, Fatigue and Frequency Domain Analysis with LS-DYNA by Yun Huang.
