Reply To: Bounceback boundaries(Physical and lattice coordinates)

[jjessberger]

Dear Abhijeet,

The numerical geometry (and therefore the physical and lattice coordinates of your grid nodes) does not depend on the boundary conditions (in fact they are set in advance).
Setting some nodes of your domain to a link-wise boundary condition does not change the coordinates of the nodes. Instead, it implies that the actual boundary of the physical domain lies beside these nodes.

Yours sincerely,
Julius J.
