i study icoFoam source code.

i want to modify U boundaryPatch value.

i set fixed value at inlet patch.

inlet
{
type fixedValue;
value uniform (0 1 0);
}

then i modify the source code.

/*** source code ****/

label patchID = mesh.boundaryMesh().findPatchID("inlet");
U.boundaryField()[patchID] = U.boundaryField()[patchID]*2;
runTime.write();

/************************/
but it does not work. the boundaryPatch value still is uniform(0 1 0);

please help me to solve the problem. thanks.
