NasaThermo::reportParams fails...

[nogenmyr]

I have a code that wants to access the Nasa polynomial coefficients for the loaded species. This I do through NasaThermo::reportParams(...). In that method there is a check that some two specie index variables match (if (n != index) {..)

It appears however that the integer n above is not set by the called NasaPoly1::reportParameters(...), but it remains zero at all times. Hence, I can only get the coefficients for specie 0 (when both n and index are 0). If I simply comment the check above the code works and the correct coefficients are returned. NasaPoly1::reportParameters(...) uses the deprecated integer m_index to set n, and m_index is not set properly anymore (this used to work a year ago)

What version of Cantera are you using? Class NasaThermo was deprecated in 2.2, and has since been removed. You should just be using class GeneralSpeciesThermo which works with all individual species thermo types.

I use 2.1.2, where I had no issues with this. The problem occurred when a colleague wanted to use my code, but he installed Cantera 2.2 (downloaded in say, October). I just downloaded 2.2.1, but I can see the NasaThermo class code is still there. Maybe it is not intended to be used. Thank you for pointing me to the GeneralSpeciesThermo class... I will revise my code to use that class instead!
