The Chemkin-Pro 2021 R1 Input Manual outlines how to input thermodynamic data in both 7-coefficent polynomial format and 9-Coefficient Format (NASA9).

I would like to alter a thermo.db file to include ``THERMO NASA9`` type data in this format. Will Fluent read and accept this, or only 7-coefficient?

Thanks for your help ?

Looks like Fluent caps at 8 coefficients for material properties. A UDF will allow you to use all 9, but I'd want to see graphs proving you needed more than about 5 terms!

Ok thanks !
