What are additional cards needs to applied for creating flex body with stress and strain mode data using NX Nastran specifically ?

I am able to generate flexible bodies with NX Nastran however struggling with stress strain modes addition in flex body. I would be great if you can support on this.
 
Thank you.

  • Hi Harish,
     
    I can tell you what the command are for MSC.Nastran. I suppose they should be the same for NX.Nastran but I am not sure as we only support MSC.Nastran at MSC.
     
    In the example case control section below, the bold commands will ensure proper stress and strain calculation and output to the MNF file:
    ...
    SOL 103
    CEND
    ECHO  = NONE
    METHOD = 1
    ADAMSMNF FLEXBODY=YES
    AUTOSPC(NOPRINT)=YES
    STRESS(PLOT)  = ALL
    STRAIN(PLOT)  = ALL
    GPSTRESS(PLOT) = ALL
    GPSTRAIN(PLOT) = ALL
    OUTPUT(POST)
    SET 91 = ALL
    SURFACE 92 SET 91 FIBRE Z2 NORMAL Z
    SET 93 = ALL
    VOLUME 94 SET 93 DIRECT
    BEGIN BULK
    ....
     
    Note that sets 91 and 93 can be customized and do not have be referring to ALL.
     
    I hope this helps.
