CVODE Error message

Robert

I am getting an error message in Fluent. I am modeling a dual mode scramjet combustor with hydrocarbon injection. For the Turbulence-Chemistry interaction I am using EDC. The help guide says I should use a segregated solver, but I am using coupled. I am keeping my Courant number low (O -3) and the residual setting lower than default. I know that the CVODE is embedded in the EDC. Every 10 iterations the following error occurs:

CVODE: Limit of 1000 steps reached at t = 2.487e-08s before t-end = 6.7746e-08

With the t values changing. This is a three step reaction with reversable reactions. Any help in solving this would be greatly appreciated. Thanks.
