Hello !

 

I am new to fatigue analysis in optistruct. For reference, I have followed the instructions as provided in the help file and with the same model as used in there (link has been provided for reference). I have been facing analysis failure with error code #6971. I have attached the screenshot of the error. Can anyone state the possible cause for this ?

Regards

Venkatesh

    If Hi Venkatesh,

     

    What is the element type are you using for fatigue analysis?

     

    Allowed element types are PSHELL, PSOLID, PWELD, PBAR, PBARL, PBEAM, or PBEAML

     

    For weld analysis PWELD, PBAR, PBARL, PBEAM, or PBEAML references for PTYPE field are supported only for spot weld fatigue analysis. Additionally, for spot weld fatigue analysis, PFATSPWID# fields should reference corresponding PFATSPW entries.
