Changes

EM.Tempo supports four types of domain boundary conditions: * PEC* , PMC* , Convolutional Perfectly Matched Layers (CPML)* and Periodic Boundary Conditions (PBC) . By default, all the six sides of the computational domain box are set to CPML, representing a completely open-boundary structure. Different boundary conditions can be assigned to each of the six walls of the domain box. The periodic boundary conditions are special ones that are assigned through EM.Tempo's Periodicity Dialog and will be discussed later under modeling of periodic structures. The current release of [[EM.Cube]] allows periodic boundary conditions only on the side walls of the computational domain, and not on the top or bottom walls.
