A rectangular plate is subjevted to power spectral density load. *DATABASE_FREQUENCY_ASCII_NODOUT_PSD, *DATABASE_FREQUENCY_ASCII_ELOUT_PSD and *DATABASE_FREQUENCY_BINARY_D3PSD are used for post-processing of the results. Example 6.1 from LS-Dyna training class NVH, Fatigue and Frequency Domain Analysis with LS-DYNA by Yun Huang.
