    Using a reference node, a rigid body can undergo translational/rotational movements or a heat flux etc.

    say i am constraining a node for its translational movement,and at the same node i am applying force through a rigid,an error comes up while analysing it

    *** ERROR # 2110 ***
     The dependent d.o.f. is constrained by grid or spc data.
     RBE2 element id =      15188
             grid id =        354
           component =          1.

    Is the node able to move in the direction of the force vector or is it constrained?

    Could you share snapshot or fem file of your model?

    This error seems like you have constrained the dependent nodes of the  RBE2 (element id = 15188). Constrain the independent node and try running the analysis.

    I even tried constraining the independent node but ERROR 153 shows up
