Kinematic coupling error
Kinematic coupling error
(OP)
Hello everyone,
I'm having an issue with one of my Abaqus models.
I have one model (circular beam), which I can change the coupling constraints from distributing to kinematic without any problems.
Then I have a second model, whose script I made on the basis of the first one. Now I get this error when I go from distributing to kinematic:
***ERROR: DEGREE OF FREEDOM 1 DOES NOT EXIST FOR NODE 2706 INSTANCE
FOILHALF-BOTTOM. IT HAS ALREADY BEEN ELIMINATED BY ANOTHER EQUATION,
MPC, RIGID BODY, KINEMATIC COUPLING CONSTRAINT, TIE CONSTRAINT OR
EMBEDDED ELEMENT CONSTRAINT. THE KINEMATIC COUPLING CONSTRAINT
CANNOT BE FORMED.
and also for the rest of the DOFs. I've attached the two scripts.
First one: circle_crack_3dmodel_master.inp (uses circle_crack_3dmodel.inp and circle_crack_fromhm.inp)

http://files.engineering.com/getfile.aspx?folder=8...
Second one: foil_crack_3dmodel_master.inp (uses foil_crack_3dmodel.inp and foil_crack_3dmodel_sets.inp)
The coupling constraint is located in foil_crack_3dmodel.inp

Can anybody help me?
Thanks a lot, Christian

Can I ask why it works for my first model then?

The thing is I have to run all my load cases for both distributing and kinematic coupling.
