I don't know the exact definition of that residual target. All I can say is to look in the documentation.

If you do a sensitivity analysis and show that you have set it tight enough that it is not...

If you have parameters which you do not know if they are set correctly then do a sensitivity analysis to find out if they are important. Try coupling residuals of 0.001, 0.01 and 0.1 and see if it...

You don't have to share it. What I describe is just good engineering practise: If you have a complex system of many parts and it does not work, then what is wrong? It is hard to fix as it is so...

I would get this model working accurately as a CFD only simulation before adding FSI. Putting it another way, there is no point doing the FSI model when the CFD sub-model is inaccurate.

So just do...

Max coeff loops of 200 sounds way too high. 10 is more like what you want.

Coupling solver? What does this mean? What coupling solver? Are you doing this as a FSI simulation? If so, why?

I have no idea what a NWT is. Please do not assume people know what your acronyms mean.

But the answer to your question is you have too much dissipation. This is probably due to a poor simulation...
