Title: difference among the boundary conditions (Nuemann, dirichlet, periodic, MP)
Post by: Shan on July 6, 2015, 16:09

Hello all

I have a long standing confusion regarding the usage of "boundary conditions" in "Multigrid Poisson solver". Even though I have some idea about some of the available boundary conditions, I have much confusion regarding which one is efficient for what kind of system and what they meant for.

If I am correct, Neumann is to create zero transverse electric field at the boundaries and used in gated devices. Periodic condition is for unit cell analysis of infinitely periodic systems.

some one please explain... what the Nuemann, dirichlet, periodic, Multipole conditions are stand for, and for what kind of systems each of these are suitable...

plz...
