I am simulating turbulent combustion. While working with one of the models, I realized I would have liked to have saved more of the solution variables for post processing. So I opened a new fluent, loaded the starting case file for that model, went into "Calculation Activities" and added the needed variables to the "Automatic Export" then ran the simulation. Again, the only thing I changed was the addition of more export variables.

When the simulation was run, I noticed that it gave different results for the burning velocities after about 3/4 of a second of simulation time! I am using a timestep of 1e-4s. The difference is about 6%.

So my question is, is this expected behavior??

Still wondering...
