there is an error when I Added the ion reactions into the simplified methane/air combustion reaction mechanism in Chemkin Pro
After finishing inputfiles, I runned the pre-processer, and there is no error and warning information. However, I finished all of the necessary blanks and the data, once I begun the calculation, there is an error information:

ERROR..."ENGE" OR "TEGV" MUST BE SPECIFIED WITH ELECTRONS
ERROR...NEED TO SPECIFY "XSEK" FOR ALL SPECIES OR "XSDF”
I searched the explainations the help files in for the four keywords "ENGE""TEGV""XSEK" "XSDF" . But all the explainations describe that the keywords are used just in the the plasma-relevant model, such as closed plasma reactor model, plasma PSR model and plasma plug flow reactor.
howerver, I just want to use the combustion-relevant model and add the ion reaction into the combustion reaction mechanism.

How can I do with the problem? thank you

In addation,I used the Closed homogeneous batch Reactor model. The simplified methane/air combustion reaction mechanism and the ion reactions were obtained from the appendix of the paper-----A simplified mechanism for the prediction of the ion current during methane oxidation in engine-like conditions.
The Gas-Phase kinitics Files,Thermodynamic Data Files and Gas Transport Data Files can be seen in the attachments

thank you
