The boundary Conditions at the six faces of the computational domain can be set by selecting the menu item <b>Simulate &rarr ; Computational Domain &rarr ; Boundary Conditionsâ¦</b> or by right clicking on the âBoundary Conditionsâ item in the âComputational Domainâ section of the Navigation Tree. By default, EM.Cubeâs [[FDTD Module]] assumes an open-boundary physical structure. All the six boundaries default to <b>PML</b>, or Perfectly Matched Layer, which you are going to maintain for this tutorial lesson. But the dropdown lists allow you to also choose <b>PEC</b>, or a Perfect Electric Conducting boundary, or <b>PMC</b>, a Perfect Magnetic Conducting boundary.
