Hi Noorjahan,

Welcome to the group! Can you please provide a few more details to help us help you? In particular, what command are you running that generates that error message, what OS are you using, and are you running in Matlab or Python? Can you also provide a link to the instructions you used to install Cantera?

Thanks,

Bryan

Dear Bryan,

Thanks for your concern. im using cantera version 2.3 running in Python 3.5.3 installed is windows 8.1 OS. i have referred following link for installation of cantera.

http://www.cantera.org/docs/sphinx/html/install.html#windows

the required input file for the cantera is in chemkin format which i tried to convert to ck2cti format which is acceptable by cantera software. i tried to convert it by the following method using cmd command which as follows:

C:\Python3.5.3\Lib\site-packages\cantera>ck2cti --input=heptanesymp159_mec.inp -

-thermo=heptanesymp_therm.dat

failed to create process.

When i tried i faced with the following error. hope you have understood the problem that i face. expecting best solution from you or please suggest me any other ways to convert the input file from chemkin format to ck2cti

thanks and regards,

Noorjahan

Noorjahan,

You should not run the ck2cti script from inside that directory. Instead, move the Chemkin input files to a directory such as your Documents folder, open the command prompt and change to the directory with the input files, then run

C:\Python3.5.3\Scripts\ck2cti --input=....

I think that will work. If you get an error that the command cannot be found (or is not an internal or external command) you need to look for the ck2cti.exe file, which should be somewhere in the C:\Python3.5.3 directory (but not in site-packages). Then you need to put the full path to the ck2cti.exe file to run it.

Best,
Bryan
