HI Neeraj:

It is possible that the environment is setup incorrectly, so that Chemkin doesn't know where to look for the file.  The default is in the working folder.

Please try source either chemkinpro_setup.csh or chemkinpro_setup.ksh in ansys_inc\v222\reaction\chemkinpro.linuxx8664\bin directory.  This will set up the necessary environment for running Chemkin on Linux.

Best Regards,
