Symmetric boundary conditions
Symmetric boundary conditions
(OP)
Hello
I have a unit cell(cube 15*15*15mm).
I have symmetrical b.conditions for this cell as can be seen from figure.
I would like to write this boundary conditions into my report.
But I am not sure how to write it. For that surface, I have XSYMM boundary conditions. I am wondering how if I can write it like this:
-u(U1=UR2=UR3)=0
It is the surface perpendicular to X axis, however, there are two surfaces perpendicular to X axis. How can I say that I put boundary conditions on the rear surface? I hope the question is clear.

Perhaps I'm misunderstanding the question.
RE: Symmetric boundary conditions
are you saying that the red line is a symmetric boundary ?

Red-lined region.
Over there, for instance, there is a X symmetry. I am wondering how I can write it in words?
RE: Symmetric boundary conditions
as for describing you what you're doing, how about "the model is constrained with a symmetric boundary condition applied as shown in Figure 1" ? probabkly the next sentence should be "This is valid because ..."
