Hi, i want to have a more lower residual for my analysis, what should i do?

i also want to have a more accurate results, on slat pressure coeffient, what changes should i do in my setting of openfoam?
i attach the experiment pressure coefficient result and the pressure coefficient that is resulted from my simulation in the next thread. as you see i don't have an accurate result for my slat, what should i do?

[s.m]

these are the experiment and my simulation result for pressure coefficient of slat and flap elements.
as you see i don't have accurate result for slat, and whan i change the turbulence model from kw-sst to RNGkEpsilon it become more inaccurate, why?

[s.m]

these are the experiment and my simulation result for pressure coefficient of main element.
as you see in 0 folder, i use freestream boundary condition for my simulation, this boundary give me more better result than the velocity inlet&pressure outlet.

change in fvSolution for atleast U and p to

relTol 0.0;

Ok Dear nima, would you please explain the differences between tolerance and reTol in fvSolution ?
Thank you

as you see the reduction of my residuals are really low, especially for p, i'll do what you said, and attach the residual figure.

well

relTol is relative tolerance and tolerance is absolute one so it would be clear why relTol should be 0.0
