CFD Online Discussion Forums - Multiple Inlets Adjoint

Hello everyone,
I'm trying to modify the shapeOptimizationFoam in order to account for multiple inlets. In the original createFields.H file there is a line of code that is used to set a zero alpha at the inlet

Code:

const labelList& inletCells = mesh.boundary()["inlet"].faceCells();

which i changed with

Code:

const labelList& inletCells1 = mesh.boundary()["inletLeft"].faceCells();

const labelList& inletCells2 = mesh.boundary()["inletRight"].faceCells();

and I also added

Code:

zeroCells(alpha, inletCells1);

zeroCells(alpha, inletCells2);

after the definition of alpha. Am i doing it right? The solver complied correctly without any problems.
I run the simulation and at the beginning I had this strange warning line and the simulation stopped at the first iteration of the adjoint problem.

Code:

Reading field pa



--> FOAM Warning : 

    From function const Foam::HashTable<Foam::List<int>, Foam::word>& Foam::polyBoundaryMesh::groupPatchIDs() const

    in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 455

    Removing patchGroup 'wall' which clashes with patch 6 of the same name.

This is strange because, before the simulation, I tested the mesh with simpleFoam to initialize the solution. Any idea of what is this problem?

Thank you for your help
