Grid check failed .... run simulation useless?

I was just windering, if the grid check fails (in my case due to face handedness (left-handed cells but no negative volume)) any simulation is useless?
So without a passed grid check it's not worth to start a simulation?
I anyway get convergence with the first iteration and I think it is the grid quality, but I am not sure.
Am I right?

Yeah you are right..
Grid check should not fail in gambit
Check the area where you are observing face handedness problem.
Change the grid

Do you mean that you are having the divergence right from first iteration? Are you using grid interfaces (non conformal mesh)? If so then I wouldn't worry too much for fewer left handed cells. If not then it should be fixed. However before concluding left handed faces for the divergence, I would have one more look in my case set up.
