PeriodicCarpet applies periodic boundary conditions to Carpet grids. In particular, it provides correct behaviour for the case where a refinement level overlaps the periodic boundaries, and may therefore be made up of more than one component on the same process. Thorn Periodic, by constrast, will not handle this case properly.
The usage is rather simple and resembles that of Periodic, with boolean parameters periodic, periodic_x, periodic_y and periodic_z. An important point to notice is that if CarpetRegrid2 is used, its parameters symmetry_periodic_x, symmetry_periodic_y and symmetry_periodic_z have to be set accordingly.

This section lists all the variables which are assigned storage by thorn Carpet/PeriodicCarpet. Storage can either last for the duration of the run (Always means that if this thorn is activated storage will be assigned, Conditional means that if this thorn is activated storage will be assigned for the duration of the run if some condition is met), or can be turned on for the duration of a schedule function.
