Periodic Boundary Conditions (RVE)

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

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,

Enrico
