This diagram illustrates the layout of the relevant parts of the CGNS file for recording flow equation set information.

The Zone_t node is the same as in previous figures, with the following characteristics.

• Name: Zone 1
  Label: Zone_t
  Data: VertexSize=(21,17,9), CellSize=(20,16,8), VertexSizeBoundary=(0,0,0)

Below the Zone_t node are multiple nodes, with the following two nodes shown in detail.

• Name: ZoneType
  Label: ZoneType_t
  Data: Structured
• Name: FlowEquationSet
  Label: FlowEquationSet_t
  Data: MT

Below the FlowEquationSet_t node are again multiple nodes, with the following three shown in detail.

• Name: EquationDimension
  Label: "int"
  Data: 3
• Name: GoverningEquations
  Label: GoverningEquations_t
  Data: NSTurbulent
• Name: GasModel
  Label: GasModel_t
  Data: Ideal

Below the GoverningEquations_t nodes is a node defining the diffusion model used.

• Name: DiffusionModel
  Label: "int[1+...+IndexDimension]"
  Data: (0,1,0,0,0,0)

Below the GasModel_t nodes is a child defining the specific heat ratio.

• Name: SpecificHeatRatio
  Label: DataArray_t
  Data: 1.4

And finally, below the node defining the specific heat ratio is a child node defining the data class.

• Name: DataClass
  Label: DataClass_t
  Data: NondimensionalParameter
