This diagram illustrates the layout of the CGNS file with boundary conditions defined using PointRange.
Just below the root node of the ADF file are two nodes with the following characteristics.
Just below the CGNSBase_t node is a Zone_t node, with:
At the next level, below the Zone_t node are the following four nodes.
Three lines below both the GridCoordinates_t node and the FlowSolution_t node indicate the presence of child nodes, but the child nodes themselves are omitted from the figure. Below the ZoneBC_t node are six nodes defining the boundary conditions used in this example. Only two of these nodes are shown in the figure, as follows.
Below each of these BC_t nodes is a child node defining the region over which the boundary condition acts. For the ilo boundary, this is:
