FATLOAD with LCID entry
Altair EmployeeHello,
for a Fatigue Analysis I am using the LCID entry to refer to a transient reponse load case to evaluate stress history.
My question in which manner the stress history is processed. If the Fatigue LC reads stress from h3d-file the output frequency for transient response analysis is very important.
Thanks for your comments.

Hi Prakash,
the loading frequency is not given since the transient response analysis is based an random displacement data via TABLED1 in a TLOAD1 entry.
So frequency of stress history output is defined via TSTEP Load Collector, but in TSTEP there is one Entry for Time Increment and One for Output in h3d.
So if fatigue analysis would be calculated parallel the frequency for Time Increment could be used. Is that the case?
Thanks @Prakash Pagadala that was very helpful
Hi,
It is same as loading frequency
