==ILL RYU==
===May 31, 2010===
From these benchmarks, we like to confirm if the periodic boundary condition works properly. To do that, two models are prepared as following figures. In the first model, dislocaiton loop is placed at the center of the simulation domain. In the other model, dislocaiton loop is split and is put into both right and the left surface.

To check if PBC works, forces at the nodes are printed out in each cases. If forces output in both cases are the same, we can conclude PBC works well in the thinfilm code.

=== Test cases ===
In the thinfilm code, there are several flags which can turn on'off the spectral method (DEFS += -D_TFIMGSTRESS), with or without virtual segments (DEFS += -D_NOVIRTUALSEG) and with or without the Yoffe image stress (DEFS += -D_NOYOFFESTRESS). In order to test these different cases, force outputs are compared as the following table.

== Conclusion ==
From the plot, we can conclude that PBC works well in thinfilm code, because the force and stress output fits well to each other. Moreover, we can see the traction boundary condition is safisfied on the surface of the thin film.
