SubscriberI am trying to use FITDAT to convert the NASA polynomial coefficients into the fit Chemkin accepts for the thermodynamic data. The output file does not explain what is wrong. I appreciate your help.
My input file is:
DIAG 2 Â Â Â Â Â Â Â ! print table of data vs. resulting fit evaluation
TMAX 1000
POLY NASAÂ Â Â Â Â ! expects one set of NASA-format polynomial data
GACL              Gurvich,1996a pt1 p231 pt2 p186                              Â
