Hi:

I believe the 3 temperature ranges are only supported by the NASA-9 thermo format. So, in your thermo file, you would have one block of data between THERMO NASA9 ... END, and another with the regular format data THERMO ... END.  There is a sample of this thermo format in ...ANSYS Inc\v242\reaction\data.  Below is the link to the NASA document that describes this format and includes a sample in the appendix.
