This is an image of the ADFviewer main window, and shows the structure of a CGNS file for an example unstructured grid. The window is divided into several areas, or panels.
Along the top are the menu items, followed by a series of toolbar buttons. Below these, on the left is the expandable/collapsible node tree. On the right, from top to bottom, are the node description, link description, and data description panels, a row of node-related buttons, and the node data panel.
At the top of the node tree is the root node of the ADF file, named simply "/", and shown with a folder icon. The next line is the "CGNSLibraryVersion" node, marked with a file icon.
Next is the base node for the CGNS database, named "Base" and marked with a folder icon. The left is a "-" sign, indicating that the Basename node has been expanded, and clicking the "-" sign will collapse it.
Below the Base node are nodes named "Wing", "SymmetryPlane", and "Farfield", each marked with a folder icon and expanded. Below each of these nodes is a node named "FamilyBC", marked with a file icon.
Also below the Base node is a node named "Main", marked with a folder icon and expanded. Below the Main node are the following nodes, with the names indicated.
Also below the Main node is a node named "ZoneBC", marked with a folder icon and expanded. Below the ZoneBC node are nodes named "Quads_SymmetryPlane", "Trias_Wing", "Trias_SymmetryPlane", and "Trias_Farfield", each marked with a folder icon and expanded. Below each of these nodes are nodes named "ElementList" and "FamilyName", each marked with a file icon.
In the node tree the Tetrahedra node is highlighted. In the node description panel, the parent node value shown is "/Base/Main", the node name is Tetrahedra, and the node label is Elements_t. In the data description panel, the data type value is I4, the dimensions value is 2, and the bytes value is 8. The values are shown in the node data panel.
