Conflicting results for different writeIntervals
 
Hi all,

I noticed that I get slightly different solutions for different writeIntervals.
For instance, writeInterval=0.01 and 0.05.
I am using adjustableTimeSteps by maxCo and I see that the actual times steps in the simulation are approximately 1e-4.
I set writeControl=adjustable;

Does it make any sense? I don't expect the results to be different, since the actual timestep is two magnitudes of order lower than the writeInterval...

P.S.
I am using the "compressibleInterFoamSolver", but I don't think that it is relevant.

Thanks guys,
A.
