    Share your model?

    If you keep the same 'boundary condition' but the loads are different so you get different deflection :-)

    If you keep the same boundary condition, the same loads, but the beam section was changed, you get different deflection too :-)

     

    When you say you get 2mm of variation, you have to tell us the length of your beam too. Because 2mm is a big variation for a beam of 100mm if length. But 2mm is very small for a beam of 5000mm.

    Also, please always confirm your load balance and request SPCF for checking applied loads ans reactions.

     

    Also, remember that forces are applied in the node, so check the sum of all nodes, not only the individual value.
