FRF for a column model with a hole (solid elements)

This example shows a column with a hole using solid elements. *FREQUENCY_DOMAIN_FRF is used to define x-acceleration excitation to the base. Response at different output nodes can be studied. Example 4.3 from LS-Dyna training class NVH, Fatigue and Frequency Domain Analysis with LS-DYNA by Yun Huang.
