Interior boundaries check boc

Hi,

I kindly would like to ask why interior boundary check box exists?
When it is clicked what it means. When it is not clicked and we can not select some "boundary selection", what does it means?

For example,
If at example Piezoelectric Shear Actuated Beam we do not click the check box what will go wrong

I have an intuition but i can not explain it correctly.

i searched the pdf's for it but i couldn't make out why is that.

Thanks in advance

Regards,
Ilias

Hi Ilias,

Interior boundary means that you are inside the same physical domain, which usually means continuity in FEM, and you want to impose a different boundary condition on it. So, normally you should not check it, unless you want to apply a special boundary condition to a boundary that usually is left alone.
