ISAT ABORT error

      Every time I am simulating with volumetric on for the combustion of ammonia with Stagni Mechanism, it shows ISAT abort error. I don't understand how to rectify it. The photograph is attached herewith for reference.

      It looks that the ISAT table has invalid data. Please try the following to see if the calculation runs:

      clear the ISAT table

      switch to Direct Integration (i.e., switch ISAT off) and run for some iterations to get a few chemistry updates.

      If the calculation runs, switch on ISAT and try again.
