    Hi,

     

    You can create a SPCD and refer the same in TLOAD1 card. In TLOAD1 card under load type select ACCEL.

     

    Please refer to this tutorial:

    Thanks but I sill have a problem.

    The surface I want to apply the impact is also the fixation surface in my component. I can't constrain all dof in this surface.

    Hi,

     

    If you are working on a high speed impact, I suggest you to use RADIOSS for such explicit analysis.
