  3. I have a Chemkin run with a PSR cluster that I think is setup correctly, but it is erroring out with INVALID NUMBER of PSR and then other errors reading various keywords. I am running Version 18 of Chemkin Pro. What could the problem be?

      The error is caused by missing keywords in V 18.0 that specify the number of PSR and inlets. If you add the following two lines in the input file, as a supplementary input, the project will run. MAXINL 3 ! Maximum Number of Inlet Streams NPSR 4 ! Number of Reactors This defect was fixed for V 18.2. So if you load the same project in Chemkin18.2 it will work without this modification.
