    That will most likely depend on the solver you are using. For LS-Dyna, you create a load collector and assign a LOAD_BODY acceleration to it. For ABAQUS, create a pressure load that applies to an entity set in your model. Then card edit it to type GRAV and assign the orientation cosines.

    Hello,

     

    for Radioss / Optistruct you have to create a load collector, card image 'GRAV'.
