Home » Knowledge » NVH / Fatigue » ERP for a simplified engine model
This is a simplified engine model with base acceleration. It shows how to run equivalent radiated power (ERP) problems with *FREQUENCY_DOMAIN_SSD_ERP and how to postprocess with *DATABASE_FREQUENCY_BINARY_D3SSD. Example 5.4 from LS-Dyna training class NVH, Fatigue and Frequency Domain Analysis with LS-DYNA by Yun Huang.
