pRefCell and pRefValues are no

pRefCell and pRefValues are not used when using a constant pressure outlet boundary condition which is the same as in previous versions.

Generally yes but for some cas

Generally yes but for some cases you might have to make small changes to fvSchemes and/or fvSolution. For various good reasons I have changed the way in which the pressure reference cell and value...

If you are particularly keen o

If you are particularly keen on having the linear upwind scheme implemented as a deferred correction on either upwind (as in commercial CFD codes) or central differencing we would be happy to...

No and I guess nor does any ot

No and I guess nor does any other code because as soon as the mesh is skewed the second order upwind face interpolate is not in the centre of the face, i.e. not at the Gauss point in which case the...

limitedLinearV is TVD limited

limitedLinearV is TVD limited version of central-differencing where the limiter is formulated taking into account the direction of the change in velocity. As with all TVD and NVD schemes the limiter...

The linear upwind scheme is fo

The linear upwind scheme is formally second-order but it is implemented in OpenFOAM via limited weighting factors rather than a deferred correction and it is the application if the limiter that...

I would choose limitedLinearV

I would choose limitedLinearV 1.0 for U and limitedLinear 1.0 for k and epsilon unless you experience further divergence problems in which case I would revert back to upwind on those two.
