Solid bending problem
Solid bending problem
(OP)
Hi Guys!
I'm trying to bend a pipe in Abaqus. I following this video: https://www.youtube.com/watch?v=soYwaW54WRg on my model in the picture attached. I'm using the block on top to bend the pipe underneath. The job runs and completes but nothing happens and I have the following error messages:
MPCS (EXTERNAL or INTERNAL, including those generated from rigid body definitions), KINEMATIC COUPLINGS, AND/OR EQUATIONS WILL ACTIVATE ADDITIONAL DEGREES OF FREEDOM
Output request rm1 is not valid since it requests output at a dof that is not active
Output request rm2 is not valid since it requests output at a dof that is not active
Output request rm3 is not valid since it requests output at a dof that is not active
Output request ur1 is not valid since it requests output at a dof that is not active
Output request ur2 is not valid since it requests output at a dof that is not active
Output request ur3 is not valid since it requests output at a dof that is not active
Boundary conditions are specified on inactive dof of 3 nodes. The nodes have been identified in node set WarnNodeBCInactiveDof.
There are 2 unconnected regions in the model.
Any tips or do I need to provide more information?
Thanks in advance!

I just can't understand, why people with no real understanding of Abaqus think they have to do a tutorial video...

2.1.16 Progressive failure analysis of a thin-wall aluminium extrusion under quasi static and dynamic loads
Although it is not a static analysis and also includes damage and failure, it might help you figure out your boundary conditions, interactions etc..

Any ideas?
