Is there any example of periodic boundary condition for a cubic (Unit Cell)?
As an example, bottom plane is fixed whereas top plane is -1% displacement, and result stress contours can be predicted for mesh or macro structures.
Hi,
I couldn't find an example specific to unit cell.
Here is an example on how to use periodic boundary conditions using OptiStruct: OS-E: 0705 Periodic Boundary Conditions
Hi Prakash, did you mean to attach a link or pdf file? I'm not sure where I can find the periodic boundary conditions examples in Optistruct. Please help.

Sorry,
Here is the PDF. This is an example. Please let me know if you need the files.

Hi Prakash, please share the example files with me. It's a bit hard to follow the document itself.
Hi Prakash, could you please share the .fem files, I cannot find them in the install directory.
Thank you very much,
Enrico
Hi
Please find the files attached
Thank you very much.
Could I ask for some suggestions?
I'm modeling one unit cell of an infinite tassellation (such as lattice structures); the objective is to find the stiffness of the cell, simulating different loadcases.
So, I need to use PBC on the single unit. In your opinion, what type of perbc best fits my case? I was thinking about mirror.
Thanks,
