Periodic Boundary Conditions

Please login with a confirmed email address before reporting spam

Hi all,

I have an error during solving: singular matrix..

I used the simplest geometry - cube

I apllied periodic boundary conditions from one side(A) of a cube to the opposite side(B) then I applied periodic boundary conditions from the side B to the side A.

(I applied u,v,w displasemens as a boundary conditions)

That's all I've input..

Can anyone help with this?
thanks a lot,
Alex
