Warning on boundary conditions
Warning on boundary conditions
(OP)
I m defininf symetry boundary conditions on a structure but Abaqus is giving me the following message on every node at the symetry section and is ignoring the symetry condition
DEGREE OF FREEDOM 3 IS NOT ACTIVE ON NODE 42284 INSTANCE
RAIDISSEUR-1 - THIS BOUNDARY CONDITION IS IGNORED
Can anyone help?

When i define symetry i have to block translation along direction 3 and rotation around axis 1 and 2(degrees of freedom 4 and 5)...For parts neshed with solid elements:
I have the following message for solid elements:
Degree of freedom 4(or 5) is not active in the model on node...this boundary condition will be ignored..
For the part (meshed with shell) i have the following'
Degree of freedom 3 is not active in the model..
So for solid elements do i have only to restrain displacement along direction 3?
And for the shells i dont define boundary conditions?
Thanks!

Not sure about the 'shell' elements though...please post excactly what elements you are using.

Do u think i have the warnings cause i m trying to constrain nodes which are tied to other constrained nodes due to the tied surfaces?
RE: Warning on boundary conditions
I personaly excluded that dof in the symmerty node and make the model look more tidy and save the analysis to print out unnessary message, but I think it does not matter in term of the results in either way.
It is a warning not a error, right?
