    Hi

    Please refer to this post

    curve option is for varying displacement constraints. it is not possible in optistruct perhaps, but available for certain solver

    Tank you @tinh for your instant reply.

    can you please elaborate more on curves, or give some external link for the same.

    Thank you.:)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

    Hi

    sorry because i do not use it yet.

    do you know about BOUNDARY PRESCRIBE MOTION (like in lsdyna)?

    curve SPC is something like that. You should read some solver manuals to understand detail
