This is an image of the ADFviewer main window illustrating the specification of periodic one-to-one grid connectivity. It shows the same node tree as described in previous figures, but with the addition of a node named "ZoneGridConnectivity" below the Cylinder zone node, marked with a folder icon and expanded.

Below the ZoneGridConnectivity node is a node named "Periodic", also marked with a folder icon and expanded. Below the Periodic node are nodes named "Transform", "PointRange", and "PointRangeDonor", each marked with a file icon.

In the node tree the Periodic node is highlighted. In the node description panel, the parent node value shown is "/Example/Cylinder/ZonalGridconnectivity", the node name is Periodic, and the node label is Gridconnectivity1to1_t. In the data description panel, the data type value is C1, the dimensions value is 8, and the bytes value is 8. The string "Cylinder" is shown in the node data panel.
