This will no improve the initial convergence, since the solver will stop when the relTol is 0.05. thus it will not run until 1E-12 but stop at 0.05. And pressure equation will be not converged smoothly, I guess. What are your experience on the subject? What do you mean with not efficient?

Somewhere else it has been suggested to use pressure

but its doesn't work.
First of all I define a ScalarField in my Header,

volScalarField hybrid_;

for the next step I edit the code file with a new Object

hybrid_
(
IOobject
(
"hybrid_",
runTime_.timeName(),

Please note that in my case the inlet pipe centerline run along the y-axis, but it should by easy enough to modify for other cases too. Turbulent velocity profile is calculated

Dear ngj,

Thank you so much. Today I met the pTraits in the turbulentInlet.C again. So I had a look at thread again. The codes are as follows:

As this may also be interesting to other people and I would be interested in feedback, please find the summary below:

Basics:
If the grid near the wall is fine enough (~y+<1 everywhere and at least 4-5 nodes
