I am running 2d modeling in abaqus, but the following error error shows.
The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained. Either mass must be defined or all of the translational degrees of freedom must be constrained. See the status file for further details.
The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRot1Axis have at least one axis about which the rotary inertia magnitude is zero, and the rigid bodies have at least one rotational degree of freedom which is unconstrained. Either rotary inertia must be defined at the reference nodes or all of the rotational degrees of freedom at the reference nodes must be constrained. See the status file for further details.
How can I eliminate this error?
If you have a rigid body you have to apply mass/inertia on it or you have to apply a boundary condition constraining each degree of freedom which in my point of view would not be a suitable solution for you.
You should best add a reference point on the rigid body and then in the CAE-tool add the mass/inertia on the reference point. You find this in the property-module-->Special-->Inertia-->Create-->Mass/inertia
I hope that this helps you.

The best and easy solution is, connect the reference point with a non rigid tool via rigid coupling. It will work as rigid body and ignore the warnings. additionally, uncheck all the unnecessary BCs from the tool. e.g. any non required rotation constrains.
You should use discrete rigid and connect your rigid part with a non rigid part using tie or rigid coupling tool.
