The Species Thermodynamics node () creates variables for the enthalpies, entropies, and heat capacities for all the species/surface species present in the Species Group parent feature. The purpose is to compute thermodynamic mixture properties and the heat of reactions.

This node is a subnode to the Species Group node when the Feature Nodes Available for the Chemistry Interface check box is selected on the Chemistry interface Settings window.

Select a Type selection for the thermodynamic properties. The NASA format alternative requires the setting of several polynomial constants and is typically used together with CHEMKIN import. The User defined alternative only requires input of Species molar enthalpy (J/mol) and Species molar capacity (J/(mol·K)).

This section allows import of thermodynamic CHEMKIN transport files. To import the data directly into the table columns, click Browse to locate the CHEMKIN file to be imported, then click Import. Note that this can only be done for the NASA format option.
