Reply To: Response spectrum results

Hey,

Unlike transient dynamic analysis, RSA does not solve for the system's response at incremental time steps. Instead, it combines the peak responses (e.g., using methods like SRSS or CQC) to estimate the worst-case scenario.
ANSYS displays the results at "Time = 0s" as a placeholder to indicate that these are not tied to a time progression. It signifies that the displayed results are static in nature, representing the maximum responses meaning the worst case scenario.
