Need support for Random analysis for 2022.2 version, same file works in 2021 but 2022.2 its not work
A fatal error has been detected during input processing:
*** ERROR # 3896 ***
Adjusted fatigue strength (7.100e+02) at cycle 1 is lower than fatigue
strength (2.016e+03) at static failure transition cycle 1.000e+03 in
SN curve of mean = 0.000000.
MATFAT ID = 24
FATPARM ID = 164.
getting error during 2022.2 version why?

Hello,
A static failure check was introduced in Optistruct to consider very low cycle fatigue cases. This error might reflect issues in the SN curve definition. You can bypass this check using the option NOCHK in the STFAIL continuation line of the FATPARM card.
