Hi, everyone!

I need to access velocity at boundary. Here is my code:

label patchID = iMesh.boundaryMesh().findPatchID("inlet");
const polyPatch& cPatch = iMesh.boundaryMesh()[patchID];
const fvPatchVectorField& patchU = U.boundaryField()[patchID]
//U is a vector field
forAll(cPatch,facei)
{
//do my things, calculate a vector u_sum
patchU[facei]=patchU[facei]+u_sum;
}

When I tried to compile it, the compiler told me "vectorField has no member named boundaryField"

Could anyone tell me how to access velocity at boundary?

Thank you in advance!

Best regards,

Xiangyu Gao
