Yes! The schemes used for gradients must be consistent.
For me, the problems ere that still I cannot find a way to get my runs working on with...

The easy, but a bit messy, way is to
Define a volScalarField for p, called say pRes, and a volVectorField for U, uRes.
Set pRes = fvc::.... your pressure equation.
Set uRes = fvc::......

Hi,
I have used the setup I told you successfully in almost all my runs, so I would double-check the boundary conditions. Your checkMesh does not have anything wrong.
Out of curiosity, what...

No, I don't think 0.7 is too strong. Try to figure out why k is not solved anymore, while all the rest keeps changing (if there is a reason different from being it converged).
It is really...

Hello,
the solution is not converged. You are doing a steady state simulation: residuals should be significantly lower. Set the convergence criterion at 10^-10 and wait until that value is reached...

I have a few comments on what you posted.
- First your case barely converges also with upwind (residuals of the pressure are the highest (yellow line)). Reduce the tolerances on the linear solvers...

Hi,
both limitedLinear and linearUpwind are bounded. What is different is how the boundness of the scheme is obtained (see table 4.10 of User's guide).
limitedLinear is the linear scheme...
