In an older openfoam 3 case file, the 'U' file was written as such:

dimensions      [0 1 -1 0 0 0 0];

internalField   uniform (0 0 0);

boundaryField
{
    //- Set patchGroups for constraint patches
    #includeEtc "caseDicts/setConstraintTypes"

    outerCylinder
    {
        type            fixedValue;
        value           uniform (0 0 0);
    }

    walls
    {
        type            fixedValue;
        value           uniform (0 0 0);
    }

    "propeller.*"
    {
        type            movingWallVelocity;
        value           uniform (0 0 0);
    }
}

And the case ran perfectly fine. However, with openfoam 5, this is not working. It is asking for a 'patchField entry for innerCylinderSmall' (innerCylinderSmall is a patch which did not need any entry in openfoam 3)

What changes do I need to make in 'U' to make the case compatible with openfoam5?

Thanks.

No one to answer this query? I urgently need the solution, I would be very grateful for any help in this matter.

As you can see in the case: $FOAM_TUTORIALS/incompressible/pimpleDyMFoam/propeller, there are some scripts to run the case, mainly:

Allrun and Allrun.pre.
The script Allrun calls Allrun.pre before running the solver.

So you have first to run Allrun.pre script before running the solver:

./Allrun.pre

Just if you are curious, take a look to this file [font='Courier New'']Allrun.pre [/font] to see its content.
