    thank you TGS4! you are right! every time i submitted .inp file from cae, the abaquswould overwrite the .inp file! i submitted it from command line and the buckling mode added to main analysis thankyou

    thanks for respond. this is my .inp file. maybe the place of *imperfection command in inp structure is not true. the second command line of *imperfection as well as nodes are ignored here. *Heading ** Job name: main-base Model name: shahed-main ** Generated by: Abaqus/CAE 6.13-4 *Preprint...

    Applying residual stress without using node numbers - Implicit and Explicit analysis
