would like to create apply a fully developed velocity profile at the inlet to my simulation.

I am currently using OpenFOAM 12 and I have not yet found how to do this.

I have tried several approaches without success.

For comparison, in OpenFOAM 9, applying this inlet condition:

    Inlet
    {
        type                flowRateInletVelocity;
        volumetricFlowRate  3.39e-5;
        extrapolateProfile  yes;
        value               uniform (0 0 0);
    }

would result in this inlet velocity profile (scaled to the velocity profile of the inlet):




This same information in OpenFOAM 12 results in a uniform inlet velocity (scale is from 0 to the average velocity across the inlet):



I have not yet found how to create a fully developed velocity profile at the inlet.

Thank you for any help you can give to me to get a fully developed velocity profile with OpenFOAM 12.

Edited to add: Until I can get a developed velocity profile at the inlet, I will be using an added length of flow with the slip boundary condition. This will deliver a somewhat developed velocity profile and will not result in very high pressures at the outer circumference of the inlet where the flow is in contact with the walls (noSlip) of the simulation.
