Assigning a reference point to a rigid part in ABAQUS
Assigning a reference point to a rigid part in ABAQUS
(OP)
hello,
I am running a simulation in which one of the parts is a rigid body. I have a quick question regarding the defining of reference points. Basically, when I try to run my job, I get an error message saying "The rigid part instance Part-4-1 is missing a reference point".
It makes sense that a rigid body needs a reference point, so I go back and define a reference point by clicking Tools, then Reference Point, then clicking a vertex on the rigid body. The viewport then labels that reference point as "RP-2" (I have another reference point located elsewhere in the assembly). However, when I run the job again, I get the same error message that I displayed above. I am baffled because this should be a simple procedure to assign a reference point to a part instance, but clearly I have not yet assigned a reference point to that part.
Am I doing something wrong? Is there a different way to assign a reference point to a given part?
I would greatly appreciate any help. Thanks!

In all probability, the rigid body reference node is either free to translate or rotate (or both), *unless* the zero pivot message is due to an overconstraint which the ABAQUS pre-processor decides to release (yes, that can happen) thereby causing the node to be free to translate/rotate.
