The PPDF table used in this tutorial involves only six gaseous species: C3H8, O2, N2, CO, CO2 and H2O which, for demonstration purposes, should provide a solution of reasonable accuracy. A more realistic solution could be obtained by including additional intermediate species in the table.
To define the gas components corresponding to the above species:
A new node named C3H8 will appear beneath the Gas Components node.
The components should be listed as shown below once this is complete.

The default component properties and those of the gas mixture as a whole do not need to be changed so we can now proceed to Generating the PPDF Table.
