Substructure w/ Periodic BC's?

[chrispogi05]

Dear All,

I am currently looking to implement a substructure for which I would like to employ periodic boundary conditions; the problem is that I'm not sure that I can use the *Equation keyword, which one would typically use for periodic boundary conditions, since I don't have a *Part or *Assembly keywords due to the nature of the substructure input file (Abaqus manual states that *Equation requires the part or assembly modules). Are there any work-arounds in this case?

Any suggestions on how to do this?

Thanks,

Chris

SOLVED:

Finally got to manually editing the input file and realized that although the ABAQUS keyword manual states that the *Equation needs to be nested within the *Part, *Part Instance, or *Assembly keywords, for a substructure one can simply put it below the model geometry descriptions (nodes, elements, sets).

Data check and Submit job worked fine, even with the substructure step afterwards.

Hope this helps someone!
