i am trying to simulate sheet metal bending.
die and punch were given as analytically ridid body.
the following error occured ,
kindly clarify me regarding this.

***NOTE: Contact output has been requested for at least one contact pair
involving an analytical rigid surface. For each of these pairs,
contact output will not be provided for the analytical surface, but
will be provided for the opposing surface.
***ERROR: Rotary inertia is not defined for the rigid bodies with the
reference nodes listed below, but not all rotational degrees of
freedom are constrained at the reference node. Abaqus/Explicit now
requires rigid bodies to have a positive definite rotary inertia
unless rotational constraints are applied with the *BOUNDARY option
(see the Abaqus Analysis Users Manual). Nodes that are part of a
rigid body do not require mass and inertia individually, but the
rigid body as a whole must possess mass and inertia unless
constraints are used. To remedy this error, either add rotational
constraints to the reference nodes with the *BOUNDARY option or add
inertia using the *ROTARY INERTIA option, whichever is appropriate
to obtain the desired response. A node set named
"ErrNodeRefNodeNoRotInert" containing the problematic reference
nodes is also created for use in Abaqus/Viewer to help locate the
error and modify the input definition.
Reference Nodes:
node: 1 instance: PART-2-1
